Rear Chuck For Porper Model B Lathe
- Thread starter brianna187
- Start date
On a Jet lathe as was mentioned, it was made for metal and not cues. So the spindle bore not being perfect is not that big of a deal as they are not usually having to hold short pieces of tapered metal with a internal collet. Cue lathes are another story all together.Michael Webb said:

I made about 30 delrin collets for the butt of a cue. These collets fit into the very end of the spindle bore. They are tapered on the i.d. to fit my butts. These collets will hold any cue from .40 inch up to 1.320 inch. These collets are not split.
For the chuck I made about 10 tapered collets for the joint work. They are split and will fit any joint size I encounter.
Basically the collets get .010 larger with each step up. Once I got the OD correct size, I parted the pieces off at 1 inch increments. Next I drilled them out so my boring bar would fit. Next I tapered each piece to the size I was looking for and then stepped up by .010 each piece thereafter.
Now I have collets that will fit everything and I did it all in 4 hours. Best 4 hours I ever spent.
Good Cuemaking,

Ice cubes in the spindle work just as great
Just be sure to indicate the adaptor before the ice melts.I stated before, when we made the adaptor for my Grizlly, we left the threaded adaptor in the lathe, spun the chuck on and bored the jaws to 1-3/8 to match the od of my tapered id collets.
Another way, much like Arnots, would be to turn a tapered od collet to match the id chamfer in the end of the spindle (if your lathe has one) then split it.
Add that to a tapered id along with split collet, and your in business I believe. As long as the chamfer is long enough.
Kinda like the ER Collet theory...
IMO.

This is what I have been using for my shaft work since day 1. The lathe I
have done this work on does not support any butt-work, but here is some
pics I put on my page some time back :

Do you put threads on your collets or how do you make them stick when you
do joint work on the shafts ?

For the small end of the shaft it goes into a self-centering 3 jaw chuck and is held by friction (this is a split Delrin collet).
The back or large end is held in the spindle by friction. I machine the OD to the proper snug fit size.
Good Cuemaking,
Arnot,
It might be that my english is not up to date and I misunderstand this, but
doing for instance ringwork on a shaft you have the fat end in the chuck and
the small end sticking out in the back of the headstock.
In this situation you have a reverse tapper, which would not hold the collet
as when you do tips.
In my case, I have external threads on the spindle (as you can see on one
of the pics) which fixates the collet and don't spit it out. My new lathe has
internal threads and I have not made any thing to this but the idea was to
test with delrin on this as well, even if I'm getting Chris's chuck.
I guess a split collet in the back of the headstock which has the reverse
tapper might fixate the collet by friction.
Anyway, good to see that two people thinks the same even if we're at
opposite ends
Sorry Lee for high jacking you're thread.

I never taper the OD - just the ID to fit the shaft or Butt section. This way you can use the collet in either direction.
Good Cuemaking,
