No Doubt Matty is Top shelf ...

Always time to work on sumthin else ... well all my collets now fit after speeding another hour or so polishing out burs/ rechasing threads . Now you are able to thread in w/ draw bar and thumb... and push collet up in spindle with ease . I still have to put back keyway and adjust tho... hopefully that's not another round of fixin the collet set.

Next thing to figure out is Spindle stroke dial calibrate / readjust (off by +.100) this is for setting an exact stop for z depth on quill.for some reason using the scale at zero its ahead +.100
perhaps if I take apart I can adjust that . anyone know on the 932 Pdf model if that can be done ?

whats id really like is to use gauge blocks with a quill stop however not going to be able to do with this design. maybe ill add a small one for 1" and less .

Also id like some ideas and or comments . . As there is no dial on the Z column depth. First anyone know the pitch of lead screw /? and if anyone had made a dial for it . Or is everyone a get a DRO for the Z column . I do plan on putting one on all axis . but still nice to have a manual dial as well. Thanks for any ideas.

Thanks Guys . Update worked on Collets and fit ect... smoothe as butter now you can slide collet up in spindle with 2 fingers and tighten draw bar with thumb and index finger . than precede to torque nut. Works like its supposed to .,.a little TLC needed to get there.
On to next issue my start capacitor for motor crapped out Matt sent a new oneout right away as soon as we verified that was issue . All is well should be up and running soon.
In near future i will be getting a DRO for at least 2 axes maybe add the z > however that does not give me a quill stop that can be set to a desired increment . What im looking to do is 3 fold ill explain as i modiphy figure out the machines limitations with power feed quill and z axis stop. I think the new Dro's are 2 months out so for now ill use indicator and make a temp DRO than decide from there if im going with 3rd axis DRO or not .
little mill/ shop update :
All in all with a few adjustments will have a functional shop in garage. Because of powered feed and total X travel on Mill had to move the fridge over yet another 5 inches . Just enough room behind door for some storage and too be able to open garage door. No worries still have the beer bait fridge. ;)

here is Pic of Mill in its new place standing tall . Nice machine I am glad I opted on The PM932 PDF w/ 220V 1..5 HP mill . I know once I work out a few bugs she will serve me well . Thanks again for all your help and support . Still have not a clue what my hobby may be but I do know my Next project. Making new Gib locks for all axes and perhaps working out a quill depth gauge for the PDF Model.

Not sure if it would fit, but a travel indicator and magnetic base might help. You can use it to find the pitch and make that dial.

Thanks for idea yes dont i just need to find out pitch than divide diam of dial to add # of divisions? I can prob add a dial to manual Z column crank anyone do this ?
it says lead screws are Acme thread 10TPI not sure if its including the Z but IMO most likely they are all the same

As far as quill z stop i will use indicator and or DRO for now than in time i am going to add a BP style Quil stop for use of gauge blocks. prob for less than 1" set up .
also going to take apart the power down feed depth see if i can calibrate it correctly with dial/ depth any one have luck with this to use as an accurate quill depth stop?
thanks :)

Mount your indicator, zero it, turn the crank exactly one turn and see how far it moves then divide that number into 1. Let's say it moved .100, so your dial would have 100 marks representing .001 each, and 1/.100 = 10 TPI.

It's good to double check. Imported machines have a tendency to use metric screws with a yankee dial and they'll be off a tad.

lead screw is it is 10PI however that is the constant that we do know now my dum Q is doesnt the amount/ divisions on the dial have to do with Diam of dial and or lead screw?
I dunno from what I see is one full rev is about .120 now what id like to know or see is the math that proves it cant seem to get ratio ?
is it the diam of lead screw yea that's it no?
Btw im just curious if I was gona make a dial for Z column crank last night I looked at set up best for me to make a tab and use a basic mag / indicator I can easily use up to 1" travel for column all I need if I decide to add DRO than maybe ill add the 3rd axis otherwise its not really needed as far as im concern 1" is plenty for face mill ops

Diameter has nothing to do with the count, other than determining how far apart the graduations are. But you don't need to know that, or even the TPI. If your indicator said .120, then divide the dial-to-be into 120 divisions.

Appears to be a metric screw, btw. 1/.120 = 8.3 TPI
Real close to a 3mm pitch (.118").

8 TPI is .125

[Kennyv]

lead screw is it is 10TPI

He said, she said. They're not telling the same story.

10 TPI has a .100" lead, of course. One full turn moves the nut .100"
That's what She Said, but He Said it moved .120".
