P1 milling machine

00:00:13

since the last video I added a digital

00:00:16

readout linear scales and I put the

00:00:19

machine on proper feet

00:00:21

and also I wanted to address some

00:00:24

some questions or comments in the

00:00:28

that I got under my last video so

00:00:31

who one person mentioned that I'm

00:00:34

that it seems that I'm awfully familiar

00:00:36

with the machine yeah of course

00:00:38

um decal FP FP series Milling machines

00:00:41

are super common here in Germany and

00:00:44

during my entire apprenticeship and my

00:00:46

professional

00:00:47

uh time at work after apprenticeship I

00:00:51

always had fp1 or fp2 Milling machines

00:00:54

at my disposal

00:00:55

we had all fp2 and one fp3 Mills in The

00:01:00

Apprentice shop the first prototype shop

00:01:03

that I was in had a fp1 fp2 and fp2 NC

00:01:10

and where I'm now in the in the Special

00:01:12

Machine building department we have a a

00:01:15

we have two fp2 machines at our disposal

00:01:18

the fp2 is just a little bit stouter

00:01:21

machine larger travels

00:01:23

and the horizontal spindle has a quill

00:01:26

which is really cool it's I think it has

00:01:29

even like 120 millimeters of quilt

00:01:32

travel means you can push the machine

00:01:33

into the role of a horizontal bore if

00:01:36

you need to and we do that from time to

00:01:38

time if we have large parts that need

00:01:40

side holes drilled

00:01:43

so that's the reason why I'm rather

00:01:45

familiar with the machines and it's it's

00:01:47

possibilities

00:01:49

so

00:01:50

one very common comment was

00:01:54

the tapping

00:01:55

if I'm going to either change out the

00:01:58

motor or add a vft to to add tapping

00:02:01

capability to the machine I'm not going

00:02:04

to do either one of them because the

00:02:06

machine has already a three-phase motor

00:02:09

that can and those can run in both

00:02:11

directions by just changing two of the

00:02:15

two of the power wires L1 against the L2

00:02:18

or L1 against L3 or 2 against three then

00:02:22

the motor will just reverse its

00:02:24

direction

00:02:25

that's way easier to handle than adding

00:02:27

a vfd to an existing machine

00:02:30

on a proper vfd installation you cannot

00:02:32

have any switching elements between the

00:02:35

vfd and the motor

00:02:37

some vfds will either burn up explode or

00:02:42

in the best case just fall out if you

00:02:45

disconnect the motor while it's running

00:02:47

from the vfd

00:02:50

you have to rewire all the switches and

00:02:54

switches to be digital signals

00:02:58

for the vfd so you get a 24 volt signal

00:03:02

to the digital input

00:03:04

on the vfd

00:03:07

I'm not going to do that that's a whole

00:03:08

lot of work you have to redo the whole

00:03:10

electric cabinet I'm just going to add a

00:03:12

foot switch to the machine a like a

00:03:15

pedal that will reverse the spindle on a

00:03:18

press of of the foot which we have that

00:03:22

at work on our drill presses and it

00:03:24

makes tapping a breeze and this will be

00:03:27

done here too so another mention was a

00:03:30

crane that's coming too

00:03:34

while the head is fairly easy for me to

00:03:37

lift and to put on the machine because

00:03:39

I'm stupid tall

00:03:42

but the indexing head and the tables

00:03:44

those are bare to lift the indexing has

00:03:47

like 40 kilograms

00:03:48

and it's awkwardly low so I got a a

00:03:54

Siege c-rail which is usually used for

00:03:57

barn doors

00:03:58

they have a load capacity of something

00:04:02

in the realm of 150 kilograms per truck

00:04:05

that runs in the sea rail

00:04:07

and I will just put one piece of rail

00:04:10

above the machine so I can pick pick for

00:04:13

example the head or the indexing head

00:04:15

off the machine move it out put it on a

00:04:18

cart and get it out of the way and move

00:04:20

table in if I need to and with a chain

00:04:23

hoist obviously

00:04:25

or a small Electrical hoist but I don't

00:04:28

like the small electrical hoists the

00:04:30

cheap ones because they are not very

00:04:32

precise in their movement so chain hoist

00:04:35

to this

00:04:37

so that's that then I got a digital

00:04:40

readout for the machine I bought the

00:04:42

digital readout directly in China from

00:04:44

ikron

00:04:45

up there icron

00:04:52

I ordered a digital readout three axis

00:04:56

and three glass scales linear scales one

00:04:59

micron resolution

00:05:02

320 millimeters 370 for the C axis and

00:05:06

174 the y-axis

00:05:10

so let's look at the linear scale

00:05:12

installation and

00:05:14

some things I took into consideration I

00:05:16

didn't film the installation because

00:05:18

it's a whole lot of cussing and drilling

00:05:21

holes with cordless drill so that that's

00:05:24

not too much of a video

00:05:27

so the y-axis is the simple stuff all of

00:05:31

them

00:05:32

the linear scale is mounted up against

00:05:34

the y-axis Ram the traveling part

00:05:43

and the read head

00:05:44

is bolted Against the Machine I used the

00:05:48

delivered Hardware to mount the read

00:05:51

head because in this case it was the

00:05:53

right Dimension and fitted and I also

00:05:56

mounted the cover over the linear scale

00:05:58

this is just an aluminum cover the scale

00:06:00

is below this I still have plenty of

00:06:03

room to operate the y-axis handle which

00:06:05

is funny enough when you stand in front

00:06:07

of the machine on the operating side

00:06:09

which is opposing to this side you just

00:06:11

reach over the back of the machine and

00:06:14

tighten this lever

00:06:16

this is this is still very fine and very

00:06:18

operational I'm I'm

00:06:20

absolutely 100 percent okay with it it's

00:06:23

a fine solution that I can live with so

00:06:26

that's the y-axis and then I just routed

00:06:28

the cable

00:06:29

with a zip tie out to the back not

00:06:32

winning any cable management prices on

00:06:35

this machine so down here we have the

00:06:37

x-axis scale this is the scale without

00:06:40

the aluminum cover that you saw on the

00:06:42

y-axis it's bolted up against the saddle

00:06:45

or the apron of the x-axis two screws

00:06:48

yeah I drilled into the machine and then

00:06:50

I machined a block that fits the angle

00:06:54

the slope on this

00:06:56

on this on this housing that is for the

00:07:01

c-axis screw and the bevel gear that

00:07:04

goes out to the side so when you move

00:07:06

the x-axis

00:07:08

read head is stationary and the scale is

00:07:11

moving along it

00:07:15

then I just drilled on an angle into

00:07:18

this casting and the aluminum Mount here

00:07:21

is bolted against the housing and then

00:07:23

the Reed head is bolted into this

00:07:25

bracket from the front with two and

00:07:27

three screws the important thing on a

00:07:30

deco tool Mill or any of the European

00:07:33

style

00:07:34

tool room meals is that the linear

00:07:37

scales are not protruding Above This

00:07:39

surface here the surface here is your

00:07:42

vertical table you cannot have anything

00:07:44

stick up above the table because what in

00:07:48

this case I have the indexing head it's

00:07:51

hanging over a little bit over the edge

00:07:53

over the edge or if you mount for

00:07:55

example a large plate or a casting

00:07:57

directly against this table to machine

00:07:59

it anything that sticks up will be

00:08:02

constantly in your way and annoy you to

00:08:05

death we have machines that work where

00:08:08

the x-axis scale is mounted up against

00:08:11

the apron and it's it's really it's not

00:08:13

it's not good don't don't do that so

00:08:17

this is this was already rather annoying

00:08:19

to mount

00:08:21

but still fine a little bit of Machining

00:08:24

on an angle but the c-axis is probably

00:08:26

the hardest on this machine

00:08:29

yeah here is my great cable routing to

00:08:31

the back master of zip ties here

00:08:34

so I have the linear scale mounted

00:08:37

against the column of the machine it's

00:08:39

bolted in with two screws again with the

00:08:42

lip seals pointing towards the back

00:08:45

means I have this weird bracket here

00:08:48

that reaches from the c-axis saddle

00:08:52

out here it clears these stocks here

00:08:56

these are the trip docks for the power

00:08:58

of pizza the power feed stops when you

00:09:00

run the machine into its extreme end of

00:09:03

the travel then it reaches around

00:09:05

reaches around and goes to the Reed hat

00:09:08

back here

00:09:10

this allows me to have the

00:09:12

the c-axis scale very protected against

00:09:16

chips and probably coolant speaking of

00:09:19

coolant I decided to not run the machine

00:09:21

with coolant because let's have a look

00:09:24

down here

00:09:25

this is the foot of the machine and this

00:09:28

is just a piece of sheet metal that's

00:09:29

sitting here and

00:09:32

this is the pickup for the coolant it

00:09:34

sits in this cast tank here and as you

00:09:37

can see I get all the

00:09:40

all the oil from the saddle lubrication

00:09:43

the saddle is lubricated via a reservoir

00:09:46

you fill it up with oil then there are

00:09:49

oil Wicks that

00:09:51

distribute the oil to all the sliding

00:09:54

surfaces and so on

00:09:56

and eventually all the oil will make it

00:09:59

into the coolant sump and anybody who

00:10:01

had to do with coolant in a machine

00:10:03

knows that this is a problem this

00:10:08

will form a seal layer on top of your

00:10:11

coolant

00:10:12

and a coolant below the oil will start

00:10:15

to get rancid all sorts of

00:10:19

life forms will start to exist in there

00:10:22

and I don't want the blob to be living

00:10:24

in here so I'm either filling the

00:10:27

machine with cutting oil which is a

00:10:30

whole other sort of mess I know people

00:10:32

who run white white oil mineral oil in

00:10:37

their fp1 and that's a nice solution it

00:10:41

also gets

00:10:43

mixed with the with the sump let's move

00:10:46

to some oil in here but well uh it's oil

00:10:52

and oil so it doesn't get bad or go bad

00:10:56

but coolant in the oil is always a

00:10:58

problem you would need either a skimmer

00:11:00

to pull off the oil from the top or you

00:11:02

add a aquarium bubbler a small diaphragm

00:11:06

pump which constantly puts air through

00:11:09

the coolant and this prevents

00:11:13

microorganism to grow in the coolant if

00:11:16

you ever had to change out coolant that

00:11:18

has gone bad you know how ugly that can

00:11:21

get so

00:11:24

no coolant for now just wipe it down

00:11:33

so no coolant for now just oil thump the

00:11:38

machine came sitting on 100 millimeter

00:11:41

square

00:11:42

wooden boards or wooden blocks

00:11:45

so you can't pellet jacket around and I

00:11:48

like the height of the machine so when I

00:11:50

got proper machine feet

00:11:52

for it I added a 60 millimeter riser

00:11:57

in combination with the adjustment nut

00:11:59

and the foot I'm again I think I'm 110

00:12:02

millimeters away from the ground now and

00:12:06

this is a good height I can operate the

00:12:08

machine sitting or standing which is

00:12:11

very nice sometimes when you work on

00:12:13

very small parts it's nice to be able to

00:12:16

sit down steady your hands Against the

00:12:19

Machine and work like that or work up

00:12:21

standing

00:12:23

just nice M60 leveling bolts

00:12:27

the machine is now leveled and sitting

00:12:30

in position after a few days I will

00:12:32

check the level and play with the bolts

00:12:34

again

00:12:35

and back there is the electrical cabinet

00:12:38

I will hate myself when when I need to

00:12:41

to work on it but for now it's just out

00:12:43

of the way and not

00:12:45

not concerning me that's a problem for a

00:12:48

future Chef on not current Stefan it's

00:12:51

time to have a look at the slotting head

00:12:54

or shaping head I had it on the machine

00:12:56

I test run it but I noticed that it's

00:12:59

really really dirty and I'm not

00:13:02

confident of running it over extended

00:13:04

period of time without having a look

00:13:06

into it

00:13:08

so I brought this over

00:13:11

and we're most likely first going to

00:13:13

pull off these four screws here so we

00:13:16

can take this Ram adapter off the actual

00:13:21

slotting head so let's get it vertical

00:13:28

here you can see the drivetrain

00:13:31

this is the gear that intersects with

00:13:33

the gear on the horizontal spindle of

00:13:35

the fp1 and this is driving the ram in

00:13:39

and out

00:13:45

oh interesting that's not a screw

00:13:48

that's a hollow knot that's a nut with

00:13:51

an internal hex

00:13:57

okay these are the four nuts now we

00:14:00

should be able to pull this off

00:14:06

or maybe I should take a look into the

00:14:09

drawing first

00:14:10

I went on the internet and I had a look

00:14:12

and I found a manual that explains how

00:14:15

to take it apart and first of all you

00:14:18

set the stroke to zero for whatever

00:14:20

reason

00:14:23

and then you loosen the stroke adjust

00:14:26

your screw in front here

00:14:40

like this and then you should be able to

00:14:42

pull it off

00:14:44

that's a whole lot of things more than I

00:14:47

expected to be honest

00:14:50

and one of the screws fell in there so

00:14:56

normally the heads have a t-nut running

00:14:59

in the slot and a screw and this head

00:15:02

here appears to be using a t-slot screw

00:15:08

and a nut with an internal hex which is

00:15:12

kind of an interesting solution

00:15:14

this is the slotting head itself

00:15:17

with the RAM and it looks really really

00:15:19

good when I look in there and we have

00:15:21

the yoke

00:15:25

with with the stone here and the screw

00:15:27

which intersects in this adjuster this

00:15:31

this thing here

00:15:33

is adjustable for the stroke

00:15:36

Moves In and Out And to be honest

00:15:38

looking at it I'm not

00:15:40

I'm not going to take it apart very far

00:15:43

because wow this looks really really

00:15:46

good

00:15:52

I know that there is a planetary gear in

00:15:55

there or a internal gear more not a

00:15:58

planetary

00:15:59

I'm not too keen on taking all of this

00:16:02

apart

00:16:03

I was expecting it to to look awful on

00:16:06

the inside and the waist to be like

00:16:07

threaded up

00:16:09

I might pull the ram here

00:16:12

I'm surprised to see a Gib made of brass

00:16:14

or bronze

00:16:16

didn't expect that

00:16:24

foreign

00:16:29

but I would like to clean up the ram

00:16:34

this whole thing looks like it was

00:16:36

sitting in the corner of a shop never be

00:16:38

used

00:16:40

and just getting dirty which is nice

00:16:42

that means

00:16:44

that this thing is in excellent

00:16:46

condition

00:16:48

probably

00:16:49

most likely Maybe

00:16:52

let's see how we can get the Ram out of

00:16:55

there

00:17:01

so first we remove these cover plates

00:17:05

there are slotted head screws so I'm

00:17:07

really bearing down on the screwdriver

00:17:09

and I choose a screwdriver that's very

00:17:12

exactly fitting because I don't want to

00:17:15

strip out the screws or the the slots in

00:17:19

the screws that looks super amateur

00:17:31

uh the the first plate doesn't come off

00:17:33

yet because the small

00:17:35

scale that

00:17:38

shows the stroke is still screwed on

00:18:02

first plate this off it was just stuck

00:18:05

by the by the oil a little bit

00:18:09

okay removing the scale different

00:18:12

screwdriver smaller screw

00:18:16

and with the scale removed

00:18:20

I can also pull off the cover plate

00:18:26

loosening those set screws these hold or

00:18:30

secure the set screws that press the

00:18:33

give against the ram

00:18:35

backing off the Gibb screws somebody

00:18:37

painted over them

00:18:47

with this design you cannot slide out

00:18:49

the Gip

00:18:50

uh the Gibb is held in place with two

00:18:53

dowel pins

00:18:55

removing this top cover this has a felt

00:18:59

liner in it to

00:19:02

first of all be a wiper to to pull off

00:19:05

the

00:19:06

pull off any dirt off the ram before it

00:19:08

goes into the slideway and also it has

00:19:11

is a oil reservoir and helps the

00:19:14

lubrication

00:19:16

cover-up comes up pretty hard because

00:19:18

there is sealing paper in it that got

00:19:22

stuck to the other part very very firmly

00:19:27

so a ram can be moved by hand now very

00:19:29

easily but it doesn't come out because

00:19:32

the

00:19:36

the connection Rod is still in there

00:19:40

so I need to find out how to remove the

00:19:42

crank pin

00:19:43

removing the

00:19:45

Circ fitting that's for lubricating the

00:19:48

slotting head by the way the entire

00:19:50

slotting head is oiled it doesn't get

00:19:51

any grease on it for lubrication that's

00:19:54

important

00:19:56

so a quick research on the internet told

00:19:58

me that after you remove the

00:20:01

lubrication fitting in front of the ram

00:20:04

you take a copper drift and you can

00:20:06

Hammer the crank pin out to the back

00:20:10

it's it's a it's a decent press fit but

00:20:14

it's as you saw that was maybe a six

00:20:16

millimeter piece of round copper

00:20:19

and there is a connection route with the

00:20:21

PIN

00:20:24

now we can finally pull the ram

00:20:27

the screws that have been painted over

00:20:31

I want to remove the paint of course I

00:20:33

put them in some acetone in a Petri dish

00:20:37

and just wait for the paint to loosen up

00:20:39

and then I will use

00:20:42

gloves tweezers and a wire brush to

00:20:45

remove the remaining paint from these

00:20:47

screws looks looks super amateur like if

00:20:51

you when you have over painted screws or

00:20:53

set screws on a machine

00:20:56

for the remainder of the of the machine

00:20:59

I'm using this stuff

00:21:01

uh Grand Green Plus

00:21:06

Flex cleaner I think this is a rebranded

00:21:09

bio Circle

00:21:11

as far as I can tell it's

00:21:14

um since I don't use brake cleaner in

00:21:16

the shop because I don't like it I I

00:21:18

dislike the smell I like how it behaves

00:21:21

and it's expensive well this stuff is

00:21:24

expensive too and yeah I just don't like

00:21:27

it I this is a watery cleaner a it's

00:21:31

fancy dish soap

00:21:33

but it works extremely well and doesn't

00:21:35

attack most machine paints

00:21:38

as far as I can tell this shaping or

00:21:40

slotting head was never really used

00:21:42

maybe for a few

00:21:44

few hours but it's basically new

00:21:48

the scraping in here is in absolute

00:21:51

perfect condition the sliding surface

00:21:53

here is in perfect condition apart from

00:21:56

one or two spots in fact where we have a

00:22:00

storage damage and I will zoom in a

00:22:01

second and you will see what I mean

00:22:05

it's all nothing is beat up nothing is

00:22:08

damaged

00:22:10

there are no wear marks on the sliding

00:22:12

surfaces the Gibb looks in perfect

00:22:14

condition

00:22:15

the the mechanics the gearing here feels

00:22:20

silk smooth

00:22:21

if I had to guess

00:22:23

because it's painted over somebody

00:22:25

purchased the fp1 mill

00:22:28

with the complete accessory cabinet

00:22:32

in Gray

00:22:33

and at some point in time the company

00:22:36

that purchased this machine decided that

00:22:39

gray is not a modern color anymore and

00:22:41

had everything repainted probably the

00:22:44

mill and everything in the accessory

00:22:46

cabinet too and most of the time when

00:22:48

that happens I have seen that off net

00:22:52

um in the industrial environments when

00:22:53

machines get repainted the people who

00:22:56

come in and do the repainting well there

00:22:57

are painters not machine Builders they

00:23:00

paint the machine with everything

00:23:04

so that's the reason why screw heads and

00:23:06

something like that is often over

00:23:07

painted

00:23:09

but in general it's not a terrible paint

00:23:11

job it's just they painted over

00:23:14

everything

00:23:15

so I cleaned everything

00:23:18

stoned all the sliding surfaces

00:23:21

the small parts are here in a

00:23:25

for cleaning

00:23:27

just to get the the old oil off

00:23:31

I'm definitely not going to take apart

00:23:34

the

00:23:35

the final drive here

00:23:38

it feels very good there is literally

00:23:45

close to no backlash feels silk smooth

00:23:50

not going to touch it I just wanted to

00:23:52

have this apart because I wasn't sure if

00:23:55

there is any seizing on the waves or

00:23:58

something like that but that was

00:24:01

that concern

00:24:03

wasn't a real issue

00:24:07

so here's the crane so the crank has a

00:24:10

needle bearing up here where it rides on

00:24:12

the on the crank pin and the lower pin

00:24:15

that runs in the ram has a bronze

00:24:17

bushing

00:24:19

with a spiral oil Groove in there and

00:24:23

also

00:24:25

oil holes in the PIN

00:24:28

so that's done properly you might be

00:24:32

disappointed that I'm not going to take

00:24:34

this apart

00:24:36

but what it is is there is a internal

00:24:40

gear a gear where the teeth showed to

00:24:43

the inside and a small pinion running on

00:24:45

the inside not more

00:24:47

and the adjustment for the crank for the

00:24:50

stroke is just a screw here that's this

00:24:53

one here

00:24:58

and this is just moving

00:25:01

in and out like this really no rocket

00:25:05

science here

00:25:07

so I'm going to put this back together

00:25:09

this is the aluminum casting on top this

00:25:12

holds a piece of felt I washed and

00:25:15

cleaned and oiled the felt should be

00:25:17

clean enough

00:25:18

or should be clean

00:25:20

and this is just going back on top

00:25:24

also the the scale that shows the stroke

00:25:27

cleaned up extremely nice

00:25:30

interestingly enough the Gib

00:25:32

is made out of brass

00:25:36

I'm I'm really curious either decal

00:25:41

ditch brass gifts at some point on the

00:25:43

slotting head or this is an extremely

00:25:45

clean rebuild and the Rebuilder choose

00:25:48

to use a brass skip but to be honest

00:25:51

it doesn't look like a rebuild it's

00:25:56

it's all just it

00:25:59

when you when you get a rebuilt machine

00:26:01

usually you can't tell it's rebuilt

00:26:04

it's just little things but this doesn't

00:26:06

feel like a rebuild it's almost like

00:26:09

like this thing

00:26:11

is like it came from the factory never

00:26:14

used

00:26:16

so and here is the damage I was talking

00:26:18

of at first I was thinking that the ram

00:26:19

is broken in two spots and welded back

00:26:21

together but it isn't what this is is

00:26:26

this line here describes the point where

00:26:28

it

00:26:29

where the ram was sticking out the

00:26:32

slotting head and over the years crud

00:26:35

and Gunk and coolant and water was

00:26:38

collecting on this line and that created

00:26:41

a rust line and it has eaten away

00:26:44

material this is not just discoloration

00:26:47

this is material missing

00:26:50

and at some point in time somebody moved

00:26:52

the RAM and the same thing happened here

00:26:54

again thank you

00:26:58

um I stoned it cleaned it up as good as

00:27:01

possible it's all the way around it's

00:27:02

here too of course

00:27:05

um shouldn't be a major problem

00:27:07

I will I will

00:27:10

have an eye on it make sure there is no

00:27:12

dirt moving inside the RAM and

00:27:15

making creating a real problem on this

00:27:18

in this two spots

00:27:21

but yeah that's annoying

00:27:26

but that's that's used machine that's

00:27:29

used machine risk

00:27:31

it's not terrible

00:27:32

could be worse could be a large chunk of

00:27:36

ceased material on the waist too so

00:27:39

that's fine while we're here we can look

00:27:41

at the gorgeous grinding on on this on

00:27:45

the surface here it's really

00:27:49

excellent condition

00:27:51

if we don't look at this

00:27:55

same out here we have all the oil

00:27:57

channels properly done in a thick sack

00:27:59

no straight lines

00:28:02

hey shoveling

00:28:04

no straight lines because that will

00:28:07

create a wear Mark or a non-wear Mark

00:28:10

that can interfere with the

00:28:13

with the way where the oil Groove stops

00:28:16

and the slotting head itself has some

00:28:19

gorgeous scraping in here

00:28:24

completely Mint Condition this this is

00:28:27

really this is an odd thing to see these

00:28:31

slotting heads often when you see see

00:28:34

them disassembled are beaten to hell and

00:28:36

this one

00:28:38

really is not it's it's good it's I'm

00:28:43

I'm very pleased to see that

00:28:46

so after inspecting everything

00:28:48

giving a wipe down and it's time to

00:28:51

reassemble the slotting head

00:28:55

the Gibb final cleaning

00:28:58

goes back in place it's aligned with two

00:29:01

dowel pins so it doesn't

00:29:03

slide in the axial Direction

00:29:07

between the set screws that are just the

00:29:10

side play of the Gibb

00:29:12

and the kip itself are

00:29:16

push-up pieces that have the angle of

00:29:19

the Gip cut onto their end that's a very

00:29:23

neat solution and way better than pointy

00:29:26

set screws against the Gibb

00:29:29

adding the set screws

00:29:31

as I said these press against The Pusher

00:29:33

pieces and Pusher pieces press against

00:29:35

the Gib

00:29:37

this makes adjusting knee give way nicer

00:29:44

next are the set screws that lock

00:29:47

the adjuster set screws for the Gib in

00:29:50

place

00:29:51

these were later only tightened

00:29:55

very very lightly you don't want to

00:29:58

squish the thread of the adjuster set

00:30:01

screws with those

00:30:04

before we put the RAM and we add a

00:30:06

little bit of oil just so we don't do a

00:30:09

dry assembly

00:30:17

and inserting the ram that's why we let

00:30:19

the set screws for the Gib adjustment

00:30:21

relatively loose otherwise this is a

00:30:24

bear to get in

00:30:28

and a Peak from the back

00:30:32

we add a little bit of whale just to

00:30:36

so we don't move it dry

00:30:42

next part is the connection rod with the

00:30:46

crank pin this goes

00:30:49

inside the ram there is bore in the RAM

00:30:53

and it gets pressed back in or in this

00:30:55

case hammered in with copper drift

00:31:03

when hammering the pin back in place

00:31:07

I stop every few hits and check if

00:31:11

if the connection Rod is moving freely

00:31:14

and not binding up somewhere

00:31:18

just to make sure that it has clearance

00:31:19

when I

00:31:21

Hammer the pinhole you could do this in

00:31:23

a press too but the Press fit on this

00:31:26

pin is not crazy tight so using copper

00:31:29

drift works perfectly fine

00:31:45

and then it's time to put the ram

00:31:48

assembly back onto the slotting head

00:31:51

this is kind of tricky to line up all

00:31:53

the four

00:31:55

bolts

00:31:57

and The Eccentric crank pin

00:32:01

and the crank pin also has a key to it

00:32:04

so that's need to be keyed into the

00:32:07

other part too and that's a lot of

00:32:09

cussing and trying to move stuff around

00:32:13

then finally you can put on the four

00:32:15

Hollow knots the internal hex nut these

00:32:19

are really weird

00:32:22

and tighten them down and you're good to

00:32:24

go

00:32:32

and then you take the whole darn thing

00:32:34

apart again because you forgot this one

00:32:36

single screw

00:32:40

this goes into the

00:32:42

upper bore of the connection rod and

00:32:45

screws into The Eccentric pin thing is

00:32:48

bare to put back together you have to

00:32:51

line up the four bolts with with the

00:32:53

holes and you have to line up the crank

00:32:56

pin

00:32:58

with the crank disc and also there is a

00:33:02

key in the crank pin that needs to be

00:33:04

lined up with the crank disc and then

00:33:07

you have to screw it all together from

00:33:10

the front with the screw that I showed

00:33:12

you that I forgot

00:33:13

so that's annoying so but it's back

00:33:16

together

00:33:18

it's all oiled up

00:33:21

and next I'm going to put it back on the

00:33:23

machine and we will have it run and then

00:33:26

I will adjust the side play on the ram

00:33:28

because right now the Gibb is just

00:33:31

snucked down a little bit oh and I

00:33:34

realized that I need to remove this

00:33:36

cover plate again because

00:33:38

under this cover plate there are the

00:33:40

screws that lock the Gibb screws in

00:33:42

place

00:33:44

but that's only four screws I also took

00:33:47

a furniture dolly and

00:33:51

narrows it down a little bit with the

00:33:53

circular saw and just some scrap wood to

00:33:55

build a dolly for the slotting head

00:33:59

slowing here just

00:34:01

sits

00:34:03

in and these two blocks and back here I

00:34:06

have two two keeper plates that

00:34:08

interface with the dovetail of the

00:34:11

slotting head and to get it out

00:34:14

just pull it forward a little bit and

00:34:16

then you lift it which I'm not going to

00:34:18

do right now because it's heavy

00:34:21

but that will be

00:34:25

way easier once I have a crane in place

00:34:28

and why do I have it on a rolling cart

00:34:30

because it can go back there and out of

00:34:33

the way and I'm just going to put a rag

00:34:35

over it so I don't get another situation

00:34:39

where dirt accumulates on top of the RAM

00:34:42

and spoils the sliding surfaces again

00:34:49

this is probably not the permanent

00:34:51

solution that I'm going to use but for

00:34:53

now it's a solution that's out of the

00:34:54

way and I can

00:34:56

continue on working

00:34:59

with all organizations shop organization

00:35:01

there is never the best solution in fact

00:35:05

with all of shop work there is not the

00:35:07

perfect machine there is not a perfect

00:35:09

tool there is not the perfect surface

00:35:12

finish

00:35:13

there is not the perfect organization

00:35:15

system and there is not the perfect

00:35:17

storage so

00:35:19

say goodbye to perfect amounted the

00:35:23

slotting head back on the machine

00:35:25

and now it's time to set the gear right

00:35:27

because I just put it in there and made

00:35:30

it very loose so I had some chance to

00:35:34

actually put it back together so putting

00:35:37

it on the machine is is nice because

00:35:39

then it's rigidly mounted and I can yank

00:35:41

on it and check for side play in the the

00:35:45

dovetail I have my indicator stand set

00:35:47

against the RAM and the indicator

00:35:49

against the housing of the

00:35:52

slotting head so I have the shortest

00:35:54

possible measuring loop back against a

00:35:57

rigid

00:35:59

so if you put the indicator stand for

00:36:02

example here on the rotary table and

00:36:04

measured against the ram you add all the

00:36:06

other elements for example the y-axis

00:36:09

Ram into the equation and you don't want

00:36:12

that you want just to measure

00:36:14

the play between those two parts

00:36:18

so you zero your indicator well you

00:36:22

don't need to zero it to be honest I

00:36:24

barely zero dial test stickers I just

00:36:27

look at the movement of the needle then

00:36:29

You Yank on it and that's a solid

00:36:34

0.09 millimeters

00:36:37

that's a little bit much and the idea is

00:36:40

we start in the center let's move the

00:36:42

indicator to the center

00:36:43

make sure we have some range

00:36:51

then we start in the center and we just

00:36:54

set this screw here a little bit tighter

00:37:13

that's that's a little bit over

00:37:16

0.02 millimeters gonna leave it like

00:37:19

that for now

00:37:21

just move

00:37:23

a little bit further down

00:37:25

whoever in the world invented magnetic

00:37:29

screwdrivers never needed to work in a

00:37:32

machine shop it seems

00:37:47

you don't want to set it to zero

00:37:49

otherwise there is a serious chance of

00:37:54

galling the way

00:38:06

and all honestly the way I set Gibbs

00:38:09

most of the time is I screw the screw in

00:38:11

completely then I just back it off a

00:38:14

little bit

00:38:18

that was a little bit much

00:38:22

and honestly

00:38:24

um

00:38:26

tipped Gibbs are nice teapot gives a

00:38:29

really nice to set but a good and

00:38:31

well-designed

00:38:33

straight give like on this head here

00:38:36

is perfectly fine

00:38:37

just a little bit more adjustment

00:38:47

I wish the import machines had more

00:38:50

straight Gibbs instead of tapered dips

00:38:53

because it's easier to make a

00:38:57

straight give

00:38:59

if you're not down to perfect precision

00:39:03

because the you can dial it in for

00:39:08

non-parallelism in the male part of the

00:39:11

dovetail

00:39:14

now I know that all screws are are set

00:39:17

and now I can start to tighten these

00:39:20

these radial screws that press against

00:39:23

the set screws to lock them

00:39:25

you don't really need to tighten them a

00:39:27

lot it's just

00:39:29

so the screws don't move out on the on

00:39:32

their own

00:39:37

it's in my opinion better than the hex

00:39:40

nut on the outside because when you

00:39:41

tighten the hex nut

00:39:43

to lock the set screw like many lathes

00:39:46

have this

00:39:47

you always move the set screw a little

00:39:49

bit even if you use a wrench and a

00:39:51

screwdriver or a wrench in in

00:39:54

combination against each other

00:39:56

when I go back to both extreme ends of

00:39:58

the ram

00:40:00

and check if I have

00:40:03

any signs of life left and the answer is

00:40:07

no

00:40:12

and that's to expect when you tighten

00:40:15

the

00:40:17

the safety screws out here

00:40:20

that's a little bit of back and forth

00:40:22

then

00:40:24

you just do what's necessary to get

00:40:29

to get your give set right

00:40:32

yeah that feels way better that's like

00:40:35

10 microns

00:40:51

okay

00:40:55

I'm gonna leave it like that for now now

00:40:58

I will set a little bit of a larger

00:41:00

travel and see how it behaves when I

00:41:02

hand crank it I set it to 40 millimeters

00:41:04

of stroke and I'm running it at

00:41:07

16 Strokes per minute that right yeah

00:41:26

and I'm just listening to it and seeing

00:41:29

how it behaves

00:41:31

also I'm going to hand crank it

00:41:35

just a few times up and down and

00:41:40

see how it behaves looking at the oil

00:41:43

film that forms on the on the dovetail

00:41:48

so

00:41:50

when I Yank on the ram now you will see

00:41:53

something interesting

00:41:56

it moves by 10 microns

00:41:58

then it goes back

00:42:04

and I get the same in the other

00:42:06

direction if I could exceed some force

00:42:08

on here and what you saw here is the oil

00:42:11

film that's the oil the Whey oil 68

00:42:16

ISO whey oil

00:42:20

that's why it's moving

00:42:23

so I'm going to leave it like that

00:42:25

it's fairly tight but if I use the the

00:42:29

shaper for a very long time with a very

00:42:31

long stroke I can always loosen up the

00:42:33

give a little bit but I'm mostly doing

00:42:36

very small stuff and I need a tight RAM

00:42:38

for this

00:42:40

slotting tools for the slotting head The

00:42:43

Tackle head uses 16 by 16 millimeter

00:42:46

square shanked tooling and that's huge

00:42:49

that's about the size this is 16 by 16.

00:42:53

so I made this adapter out of two locks

00:42:57

33 which it pre-hardened

00:42:59

or pre-treated tool steel which machines

00:43:03

very nicely and grinds very nicely and

00:43:06

gave it a 16 by 16 millimeter shank and

00:43:10

a slightly larger head and you will see

00:43:12

in a second why

00:43:14

with an M6 screw and an eight millimeter

00:43:17

Precision bore here so I can use my

00:43:20

regular eight millimeter shanked

00:43:24

slotting tools I used to use these in

00:43:26

the quill of my Optimum milling machine

00:43:29

and I want to continue to use them

00:43:31

because they work great

00:43:33

and I can just put them in here lock

00:43:36

them with screw I'm not using a set

00:43:38

screw for a reason the this is a great

00:43:41

10.9 second head cap screw and it uses

00:43:46

full size regular sized five millimeter

00:43:49

key

00:43:51

so I can tighten it properly if I use a

00:43:54

set screw I have to go one size lower

00:43:57

with the hex key and those are prone to

00:44:00

strip

00:44:02

even if you buy a hardened one

00:44:04

45h

00:44:07

set screw

00:44:08

this is still nicer

00:44:11

and this just goes in it rests against

00:44:13

the bottom of the board this is 25

00:44:15

millimeter deep board or reamed a flat

00:44:18

hole on the ground

00:44:20

or flat bottom and this will do very

00:44:22

nicely

00:44:24

a four millimeter tool

00:44:29

lock it in and you're good to go

00:44:31

it's mounted in the

00:44:33

slotting head so you're looking onto the

00:44:36

underside of the slotting head if you

00:44:38

look up here you see a moving part that

00:44:40

has a square broached into it and that's

00:44:43

when it's not outside here it tightens

00:44:47

against

00:44:49

another part that it's writing in

00:44:52

with also a square approach into it and

00:44:54

tightens the tool that way or holds it

00:44:57

that way and now for this shoulder the

00:45:00

answer is very easy why I did this

00:45:03

this is so the shoulder rests on the

00:45:06

underside of the ram which is machined

00:45:09

and aligns my holder automatically

00:45:12

straight

00:45:18

which is very nice because I don't have

00:45:21

to do any alignment now I just

00:45:24

put

00:45:26

one of my eight millimeter shank

00:45:28

slotting Tools in here if I yeah

00:45:33

a little bit of alignment is needed

00:45:37

a little bit of alignment is needed to

00:45:40

get The Cutting Edge Square to the

00:45:42

travel of the machine

00:45:44

and this is honestly

00:45:46

simplest to be done with a pair of

00:45:49

parallel pliers and an indicator no

00:45:52

signs here

00:45:57

foreign

00:46:09

okay that's good enough that's within 10

00:46:12

microns

00:46:14

well it's probably better because the

00:46:16

indicator doesn't show it anymore

00:46:18

so

00:46:20

I have either to consider this good

00:46:22

enough or take use a more precise

00:46:25

indicator

00:46:55

I'm using the indexing head on the fp1

00:46:59

now for quite some time with the

00:47:02

self-centering voice on top of it or

00:47:04

with the collets directly in the spindle

00:47:07

and the 40 taper of the spindle

00:47:09

but sometimes I also need a

00:47:12

three child check just to hold parts

00:47:14

that are slightly bigger in diameter and

00:47:16

round and first I was thinking about

00:47:20

making or getting a 40 taper shank for a

00:47:24

something like 100 millimeter three

00:47:26

charge check and put it directly in the

00:47:28

spindle but I already have this nice

00:47:30

flange which sits on top of the spindle

00:47:34

and I can just pull off The

00:47:36

self-centering Voice here

00:47:38

it's fairly easy you could just take off

00:47:40

the two jars

00:47:43

and you close it all the way

00:47:53

then there are four socket hat cap

00:47:56

screws M6

00:47:58

I drilled and kind of board the holes in

00:48:00

the body of device myself the but the

00:48:03

body is hardened

00:48:05

but with a

00:48:09

carbide drill and a carbide end you know

00:48:11

for kind of boring it wasn't a big deal

00:48:14

I did this still when I had the optimum

00:48:17

fmb4

00:48:18

the Optima before is perfectly capable

00:48:21

of heart Drilling

00:48:23

materials like that too so then we can

00:48:25

pull off the arise here

00:48:33

so some might recognize this Chuck I

00:48:36

bought this years and years ago it's

00:48:38

very it's sub 100 euros when I got it I

00:48:42

think it's 100

00:48:44

100 millimeter body diameter

00:48:47

yeah 100 millimeter

00:48:50

I reground the top of the Jaws because I

00:48:52

needed it to be able to rest Parts flat

00:48:55

on it and run through

00:48:58

and also took it apart and cleaned it

00:49:00

showed all that on video got a lot of

00:49:02

flack for buying either a cheap truck or

00:49:04

not giving a cheap check enough credit

00:49:07

or whatever people

00:49:10

were in the mood to complain about

00:49:13

also I made this flange here so I can

00:49:15

put it on my vertex 150 millimeter

00:49:18

rotary table I was thinking I I could

00:49:21

either drill the four holes of this

00:49:23

flange into my adapter plate here or I

00:49:27

ditched the adapter plate and drill

00:49:29

straight through the Chuck cut aboard

00:49:32

the holes and then drill that whole

00:49:34

pattern into my face plate here

00:49:37

and that's most likely what I'm going to

00:49:39

do because that spares me off another

00:49:42

layer of inaccuracy

00:49:45

so let's let's take this apart and drill

00:49:48

the holes through and

00:49:52

be done

00:49:55

first we remove the jaw so we can handle

00:49:58

this a little bit better

00:50:02

oh this is this is super useful took a

00:50:06

I think this is 3 8 inch

00:50:11

uh socket extension welded a piece on

00:50:14

and milled a

00:50:16

a square for the for my checks on here

00:50:20

and this goes in a small fine-tooth

00:50:22

ratchet

00:50:26

and this is very nice when you have the

00:50:28

Chuck mounted for example directly on a

00:50:30

table and you

00:50:32

can't do a full rotation with a regular

00:50:34

uh Chuck wrench

00:50:37

or you can put this in a drill chuck in

00:50:39

a cordless drill

00:50:43

to quickly change the charts if you want

00:50:46

to

00:50:47

I do that on my 5c collect Chuck so

00:50:51

let's remove the back plate

00:50:55

so these are M8

00:51:04

and what I'm expecting down here is a

00:51:06

lot of you from

00:51:08

eternity

00:51:15

there we go

00:51:16

and here's a surprise

00:51:18

no

00:51:19

no rust just mild discoloration

00:51:28

and

00:51:30

the usual old oil smell

00:51:33

but that's fine

00:51:35

note that this adapter is ground

00:51:39

because I had a good day

00:51:42

I even engraved it February 2021 I

00:51:46

surfaced ground this adapter

00:51:48

funny

00:51:49

I made this long ago but then I decided

00:51:53

to grind it

00:51:57

okay

00:51:59

but when you look at this Chuck we have

00:52:01

to hold from the back

00:52:02

but

00:52:04

there is nothing on the front so

00:52:06

yeah we're just going to drill through

00:52:08

usually you can drill through on the

00:52:10

drill chuck on a

00:52:12

on a scroll Chuck like that if you could

00:52:16

take a look here the scroll doesn't go

00:52:19

very far to the outside

00:52:22

and that means that we have enough room

00:52:23

to drill through there

00:52:27

so we're over at the drill press because

00:52:29

it's very easy to align this piece here

00:52:31

on the table of the drill press for

00:52:34

drilling

00:52:36

for recalling we have a t-nut

00:52:39

a single stud

00:52:45

we put the drill chuck over here

00:52:49

add a strap clamp

00:52:52

heavy washer and a nut

00:52:56

and stuff is way too long

00:53:03

whoop

00:53:06

this is an M8 thread on the back side of

00:53:08

this Chuck which has a tap drill of 6.8

00:53:12

millimeters which is also a very nice

00:53:14

through hole for M6 screw so I'm using a

00:53:17

6.8 millimeter drill

00:53:21

to pick up my location or to align the

00:53:23

part with the drill

00:53:26

okay

00:53:28

now we get the drill in and this tapped

00:53:32

hole

00:53:34

lock the quill now we can

00:53:38

very nicely set this up and clamp it in

00:53:40

position

00:53:43

okay there we go

00:53:45

tighten it down [Music]

00:54:03

I'm not sure what's going on with this

00:54:05

drill bit this is an atrocity of drill

00:54:09

bits

00:54:10

and the industry we call that Dole

00:54:26

[Music]

00:54:35

foreign

00:55:02

and to the front

00:55:08

foreign

00:55:09

[Music]

00:55:14

just align it with drill bit as I said

00:55:17

this is just a clearance hole not a

00:55:21

Precision hole

00:55:23

so drill press

00:55:26

accuracy and best practices will do just

00:55:28

fine

00:55:30

I have a pilot as a counter bore

00:55:35

which is very nice for this purpose

00:55:40

so

00:55:41

we basically go down

00:55:44

the height of the head on a metric

00:55:47

socket hack cap screw the height of the

00:55:49

head is always the nominal diameter of

00:55:51

the thread so on an M6 screw the head

00:55:54

height is six millimeters on a three

00:55:56

millimeter or M3 screw the head height

00:56:00

is three millimeters on a M12 screw the

00:56:04

head height is 12 millimeters so easy so

00:56:08

nice so let's go into a slower speed

00:56:17

okay there we go first one

00:56:33

I'm using the drill bit to align the

00:56:36

part because the pilot the pilot on this

00:56:39

countersink is only 6.4 and not 6.8

00:56:41

millimeters

00:56:46

foreign

00:56:50

[Music]

00:57:23

foreign

00:57:38

there we go

00:57:40

[Music]

00:57:52

okay that's all the drilling and kind of

00:57:54

boring now we need a set of

00:57:58

counter sinks

00:58:02

and we

00:58:04

chamfer both the outer edge of the

00:58:07

counterbore and you know edge of the

00:58:10

screw hole

00:58:38

and then for the

00:58:42

for the outer edge

00:59:05

and it's that easy to convert a back

00:59:08

mounting Chuck into a front mounting

00:59:12

Chuck

00:59:15

no harm done to the Chuck

00:59:17

it still has the M8 threads from the

00:59:21

back that were originally in there to

00:59:23

mount it from the back side against the

00:59:25

Chuck adapter but we also have screw

00:59:29

holes for six millimeters socket hat cap

00:59:32

screws to mount it

00:59:34

on top of something that's what we

00:59:36

wanted

00:59:38

I really like this humongous drill press

00:59:40

at least a humongous for my purposes for

00:59:43

other shops it's the small drill press

00:59:45

but one thing I dislike is this huge

00:59:49

hole in the center of the table I was

00:59:52

thinking about

00:59:53

boring out the recess either here on the

00:59:56

drill press with boring head or putting

00:59:58

it on the on the fp1 and put a nice

01:00:02

large cutter board in here with the

01:00:04

horizontal spindle and

01:00:07

make an insert

01:00:10

a replaceable insert so

01:00:13

because for when you want to drill small

01:00:17

stuff on here which you totally can

01:00:19

because this drill press goes up to 3200

01:00:21

RPM which is fairly quick for the size

01:00:23

of machine you always have to have a

01:00:26

piece of aluminum or steel here on the

01:00:28

table to support the part in the center

01:00:29

so that's the only gripe I have with

01:00:32

this machine apart from that it has been

01:00:33

very good to me

01:00:35

I'm using dial test indicator render

01:00:37

spindle

01:00:39

to Center on my face plate

01:00:43

and this is dialed in pretty good this

01:00:47

is basically zero in all directions

01:00:50

I aligned I turned it to zero degrees

01:00:53

which means that all my whole patterns

01:00:56

that I drilled so far are aligned in X

01:00:59

and Y as far as

01:01:02

the whole patterns are concerned

01:01:05

foreign

01:01:09

to change to a spot drill

01:01:12

set up to drill the whole pattern and

01:01:15

then tap

01:01:17

for the chuck

01:01:19

so here's our spot Grill six millimeter

01:01:24

okay let's see we want a whole pattern

01:01:27

um down here circular hole pattern

01:01:31

X Y plane

01:01:35

zero is on X Y we have a pitch Circle

01:01:39

diameter of 84 millimeters

01:01:45

and we have three holes

01:01:49

there we go and now we can select

01:01:54

holes one two and three

01:01:57

by moving through and the red Point here

01:02:00

indicates our current position where we

01:02:03

are in in the space of this machine

01:02:25

okay spot drilling now we change to a

01:02:28

five millimeter drill since it's a even

01:02:32

diameter shank we can hold it in a

01:02:34

collet

01:02:40

there we go five millimeter collet

01:02:43

[Music]

01:02:58

foreign

01:03:39

foreign

01:04:25

got all my holes drilled and tapped got

01:04:28

the Chuck ready

01:04:29

and I even managed to find some

01:04:33

6 by 70 millimeter screws despite being

01:04:37

extremely

01:04:39

bad assorted in those large screw sizes

01:04:43

I have a full assortment from M3 up to

01:04:47

M8 but only to 40 millimeters

01:04:50

above that length I have to order them

01:04:53

or find something that I have in storage

01:04:55

like these these happen to be stainless

01:04:58

I will get some 10.9 grade screws

01:05:04

that I might not drop

01:05:06

to mount it because stainless Hardware

01:05:09

is soft as cheese

01:05:11

and one

01:05:15

two three

01:05:19

you might notice there that there is no

01:05:22

centering feature for this Chuck

01:05:25

and just as on my rotary table I prefer

01:05:28

to dial

01:05:30

either the Chuck or the work that I'm

01:05:32

chucking on

01:05:34

in with an indicator on a rotary table

01:05:37

because usually when I use part do Parts

01:05:39

on a rotary table Precision is kind of

01:05:41

important

01:05:43

then I want the part to be indicated and

01:05:46

I don't want to rely on a centering

01:05:48

feature for the chuck

01:05:50

indicating

01:05:52

the chuck on the rotary table is fairly

01:05:54

quick let's load the Jaws back in here

01:05:58

that's number three

01:06:01

two and one

01:06:12

okay there we

01:06:13

okay for indicating we just want to

01:06:17

to very lightly

01:06:19

tighten those three screws really really

01:06:22

light we still want to be able

01:06:25

to shift the Chuck body around on the

01:06:28

face plate and I'm using a rawhide

01:06:31

Mallet here

01:06:33

so we are raising

01:06:37

oh it could be nice if the indicator

01:06:40

wouldn't run into

01:06:44

the item we're indicating

01:06:50

and then we find the high spot like here

01:06:57

and we continue this is the low spot

01:07:00

zero

01:07:04

oh this is very low because we're not

01:07:07

touching

01:07:09

I used to be good at indicating

01:07:17

okay here's the high spot

01:07:42

foreign

01:07:48

get an actual reading

01:07:56

okay zero

01:08:03

that's plus 10 micron

01:08:09

then it drops back to zero very slowly

01:08:13

okay that's pretty good

01:08:16

now we can finally tighten it down to a

01:08:19

defined

01:08:21

torque

01:08:31

or to a solid yoink on the

01:08:36

on the hex wrench

01:08:39

and since this is stainless Hardware I

01:08:42

don't want to overdo it

01:08:45

so

01:08:59

okay that's pretty good

01:09:01

that's pretty darn good

01:09:06

so and this would give me if this was a

01:09:09

work piece this would give me the

01:09:11

confidence

01:09:12

that my run out is on this part very

01:09:15

good

01:09:16

and also when I reclamp apart with the

01:09:19

same diameter

01:09:25

I could also be

01:09:27

sure

01:09:28

that my run out would be good

01:09:30

and even if I clamped something with a

01:09:32

different diameter

01:09:34

wouldn't be too far off and probably

01:09:35

good enough for most work

01:09:38

but still I think this is

01:09:41

in the long term this is better than a

01:09:43

rich registration diameter

01:09:54

thank you

01:10:19

a last thing that I added is a chain

01:10:21

hoist and a piece of rail up there to be

01:10:25

able to move it

01:10:28

back and forth and have to hook hit the

01:10:32

machine of course

01:10:34

as you can see this is the c-rail for

01:10:39

for carrying the chain hoist there is a

01:10:42

stop screw on both end so I don't run

01:10:43

the truck out of the rail which would be

01:10:45

bad under load well would be bad anyways

01:10:48

and I have a piece of c channel have a c

01:10:52

channel that I have welded the

01:10:56

The Barn Door rail too I used the the c

01:11:00

channel profile because the Barn Door

01:11:03

rail I got from a friend it's two

01:11:05

shorter pieces and I wanted one long one

01:11:07

and the C channel is a nice

01:11:12

nice stable ground for that here in the

01:11:14

center of the picture you can see the

01:11:16

seam between those two pieces of of

01:11:19

c-rail and here is the truck it runs on

01:11:22

four ball bearings has a

01:11:25

a eye hook to it and this this truck the

01:11:29

single track can is rated to 200

01:11:32

kilograms

01:11:33

the

01:11:36

the c-rail itself or the c-channel

01:11:39

profile

01:11:40

with the the rail is bolted to the

01:11:44

ceiling with all thread M12 all threaded

01:11:48

and it's screwed through the ceiling and

01:11:50

there's a large stiff in the plate on

01:11:52

top of the

01:11:53

the floor on the other side

01:11:56

with the all threat going through it so

01:11:58

I have a very large

01:12:00

area of where I spread out the load so

01:12:04

that's very that's a very solid solution

01:12:06

and currently I have a ratcheting chain

01:12:08

hoist on there this is not going to stay

01:12:10

because

01:12:12

this is fairly inconvenient with the

01:12:14

ratcheting handle up there I am going to

01:12:18

get one with a drive chain so and for

01:12:21

example to change out the head on the

01:12:23

mill all I have to do now is take a

01:12:26

short sling load sling this is rated a

01:12:30

thousand kilograms way overkill for this

01:12:32

purpose but since I don't have any

01:12:35

anything else

01:12:37

that's what I'm using

01:12:39

it could be a tiny bit longer

01:12:43

to be honest

01:12:45

so that's going in here

01:12:47

chain hoist comes over

01:12:50

I can hook it

01:12:52

pull it tight

01:13:00

get those two locking screws undone

01:13:07

get some pull on here

01:13:10

oh that's a little bit much

01:13:17

there we go oh it's

01:13:19

out of the engagement of the dovetail

01:13:27

and I can just move it out of of range

01:13:30

of the machine and drop it onto a cart

01:13:35

to get out of three and just can see

01:13:37

this head is very well balanced if if

01:13:39

you put the sling right in the spot here

01:13:42

so that's working out perfectly fine and

01:13:45

to get it back on the machine

01:13:47

it's basically the same

01:13:48

got get it into the dovetail

01:13:51

drop it on here

01:14:04

push it back onto the onto the drive

01:14:06

gear back here make sure it's meshing

01:14:16

and lock it

01:14:22

foreign

01:14:43

hook goes out of the way

01:14:45

and we can operate the mill as usual

01:14:49

and we don't have to take the the chain

01:14:51

hoist off the ceiling

01:14:55

I can move mildly behind the center of

01:14:59

Mass on the mill heads with the with the

01:15:01

chain hoist so that does perfectly fine

01:15:03

the heads are not a real big problem

01:15:06

especially the vertical Milling head

01:15:08

here this is not very heavy but it's

01:15:10

very convenient not to have it to lift

01:15:12

the slotting head is way heavier and

01:15:15

from there on it's only heavier heads no

01:15:18

not a lighter one

01:15:20

the only thing that's lighter is the

01:15:22

overarm support for horizontal Milling

01:15:24

so let's change the indexing head

01:15:27

against against the rigid table I never

01:15:30

had the rigid table on this machine

01:15:31

since I got it it was only on the

01:15:34

machine when I it arrived on the truck

01:15:36

but I removed the rigid table when I

01:15:38

pulled the machine in here because it

01:15:40

didn't fit through the door so let's see

01:15:43

how we can

01:15:45

uh Rick this up to the to a hoist and

01:15:48

move it I have never lifted one of these

01:15:51

with a crane

01:15:54

so sling goes through there to the back

01:16:00

up here through this hole in the casting

01:16:24

[Music]

01:16:29

so this will very likely not be

01:16:33

in a

01:16:35

balanced on the crate

01:16:39

let's undo these screws

01:16:53

okay it's hanging only on one screw and

01:16:56

uh

01:16:57

the lifting sling here so

01:17:01

let's see what happens

01:17:04

okay that's not too bad

01:17:06

that's very controllable

01:17:09

and I think I can get get it back on the

01:17:12

same way

01:17:13

just move it up here

01:17:21

and get it back at the teeth lot

01:17:25

presses Up Against the Machine and get

01:17:26

one bolt engaged and then we're golden

01:17:28

okay that's not terrible that's doable

01:17:32

okay let's get it off the machine and

01:17:34

put the rigid table on here

01:17:37

later I found out that lifting the

01:17:39

indexing head with a long piece of all

01:17:42

thread through the spindle of the

01:17:44

indexing head balances it very well so

01:17:48

that's probably the correct way to do it

01:17:52

and that's the mill without anything on

01:17:54

the vertical table or the apron depends

01:17:57

on who you talk to and this would either

01:18:00

be good to mount something very large

01:18:02

against it

01:18:03

or a very long workpiece that we want to

01:18:06

work with the vertical spindle on

01:18:08

or to bolt the regular rigid 90 degree

01:18:12

table on it which we're going to do now

01:18:13

because

01:18:14

without having to lift it that's a

01:18:17

breeze I hope

01:18:18

this is not the recommended way to lift

01:18:20

something like this with one eye a bolt

01:18:23

of the Tesla but the table is 30

01:18:25

kilograms and 30 kilograms of one t-bolt

01:18:29

um yeah that's not going to damage

01:18:31

anything if you tighten a M8 screw fully

01:18:35

that's several

01:18:38

several hundreds of Newtons thousands of

01:18:40

Newtons of force pulling on on a t-slot

01:18:43

so

01:18:44

don't don't even try to say that it's

01:18:47

damaging the t-slot

01:18:54

[Music]

01:19:07

so under Richard table you need to

01:19:09

remove the nuts of two of the bolts and

01:19:12

go there are only holes no sideways

01:19:14

slots in the the table so you need to to

01:19:18

line it up and move it in

01:19:21

foreign

01:19:24

just like this

01:19:27

that's it that's it

01:19:30

get it have decent centered on the

01:19:32

machine

01:19:36

get a

01:19:38

washer and a nut on there

01:19:55

foreign

01:20:00

and that was

01:20:02

that's the first time this Mill sees its

01:20:04

rigid table couldn't yeah

01:20:08

I haven't even cleaned it so far because

01:20:11

I haven't used it yet

01:20:13

um that's something we could do

01:20:15

that's the more Road or a table

01:20:18

on The Deco fp1 on the rigid table and

01:20:21

this would not really be possible

01:20:22

without the crane I could lift it on

01:20:24

here but it's really a bear to get it up

01:20:27

here Moore delivers the rotary table

01:20:29

with a very handy handle to lift it but

01:20:33

this is more kind of a practical joke

01:20:35

it's it's very deceiving it looks like

01:20:38

you can lift it but this thing is made

01:20:40

out of a lot of gravity so

01:20:43

you can lift it but you shouldn't

01:20:46

maybe with two persons it's a little bit

01:20:48

more reasonable but not really don't

01:20:50

don't

01:20:52

if you have the choice

01:20:53

so

01:20:55

um

01:20:56

yeah this is a good size originally

01:20:58

decal made a rotary table pretty much

01:21:01

the same size as the more one the decal

01:21:04

one is not as tall and the accuracy

01:21:07

rating on the moon rotary table is

01:21:11

way higher The Tackle one is plus minus

01:21:14

90 Arc seconds accuracy and this one is

01:21:17

plus minus

01:21:18

6 Arc seconds some ridiculous low number

01:21:23

at least and it's in perfect condition

01:21:25

the goo you see on here on the on the

01:21:27

surface of the table this is lps3 that

01:21:30

has dried and that's a rust preventive

01:21:32

because I use it so really I keep it

01:21:35

covered in this wax like substance it's

01:21:38

a little bit like cosmoline when it's

01:21:40

dried and it protects the rotary table

01:21:42

from from rust very very well and this

01:21:46

rotary tip literally doubles the y-axis

01:21:50

travel of the machine you can reach from

01:21:52

here to here then you can just spin the

01:21:55

work 180 degrees and move your the other

01:21:59

half of the part if it's a very large

01:22:00

part back here and you can do work there

01:22:03

too also if you only work with polar

01:22:06

coordinates this increases the accuracy

01:22:09

of the machine too because the polar

01:22:11

interpolation with this rotary table is

01:22:14

extremely accurate and you're only

01:22:16

relying on one additional axis for your

01:22:19

position so a rotary table is a good

01:22:22

option to make a machine a little bit

01:22:23

more precise if you need to so let's get

01:22:26

all this stuff back off here get the

01:22:28

rigid table back off I need I need the

01:22:30

indexing head to do some actual work and

01:22:32

not just film things here on on the

01:22:35

crane before we leave one last thing

01:22:38

that I wanted to show you this is the

01:22:40

overarm support for the horizontal

01:22:42

Milling Arbors when you lose you use a

01:22:44

long Milling Arbor with staggered

01:22:46

Cutters on them and support the moves of

01:22:49

bearing on the outboard end

01:22:51

I got this off

01:22:53

of eBay for very little money literally

01:22:57

less than 100 bucks in very good

01:23:00

condition still had the original Grease

01:23:02

on it as it seemed

01:23:04

even with the bearing block I don't have

01:23:06

the long Arbors I'm not very interested

01:23:08

in having those uh I don't expect any

01:23:11

any work

01:23:13

that requires this but this overarm

01:23:17

support has a dovetail and the dovetail

01:23:19

is very convenient way to mount

01:23:21

accessories decal used this

01:23:24

overarm support to mount the Milling

01:23:27

head that's used to pick out internal

01:23:29

corners for example when you have to

01:23:32

machine a pocket with square internal

01:23:34

Corners that's what the Milling head was

01:23:36

used for and it's pushed

01:23:38

onto the the dovetail of the overarm

01:23:41

support so that's a very good mounting

01:23:43

solution

01:23:44

and also you have the option two

01:23:47

to to extend the Wide Travel of the

01:23:50

machine this way

01:23:51

far out

01:23:55

and what I want to use it for I have

01:23:57

this precise super 65 it's a milling and

01:24:02

grinding spindle with a universal motor

01:24:04

made by precise it's a 45 000 RPM

01:24:08

spindle with

01:24:10

something something around 500 watts

01:24:13

and I was thinking that this might be a

01:24:16

good fit for a high speed Solution on

01:24:18

this machine the original high speed

01:24:19

head for this Mill runs only 6000 RPM

01:24:22

this 45

01:24:24

000. so this spans away this gives away

01:24:29

larger chump on the high speed side than

01:24:32

the high speed head

01:24:34

the high speed head was of course fully

01:24:36

taper so very heavy duty this is only

01:24:39

six millimeter collet maximum uh not

01:24:43

very heavy duty but when you look at the

01:24:46

work examples for these spindles they

01:24:48

were used for grinding milling and even

01:24:51

hard Milling hardened Steels and what

01:24:54

that's what I want to use it for

01:24:57

it can be run or directly off Mains

01:25:00

power or with the original precise

01:25:05

variac

01:25:06

adjustable Transformer it has a plug

01:25:10

outlet on the side for the spindle

01:25:13

a big knob here to change the RPM and

01:25:17

buttons to turn it on and off

01:25:19

it even shows the speed on here

01:25:32

so this is of course not the final

01:25:33

solution to mount the spindle this is

01:25:37

not a solution at all for this mock-up

01:25:39

picture I just bolted this block with

01:25:42

the spindle against the the overall

01:25:45

bearing here with one bolt just to show

01:25:48

you what it might look if I build it

01:25:51

and I want to build it in a way so I can

01:25:54

not only mount it vertically

01:25:57

but also put it at an angle for whatever

01:26:00

reason primarily for Milling with

01:26:02

extremely small Cutters and for probably

01:26:05

grinding

01:26:06

so yeah that's the super 65 spindle

01:26:10

the viewers from the US probably are

01:26:14

familiar with these I have seen them

01:26:16

numerous times

01:26:18

on on Practical Machinist and

01:26:23

lives.co.uk has a very large and very

01:26:26

comprehensive article about those

01:26:28

spindles

01:26:29

and the accessories they made for them

01:26:31

very interesting piece of industrial

01:26:33

history so that's it that's the update

01:26:37

on the deklift P1 milling machine thank

01:26:39

you all for watching and I'll be back
