Stupid lathe question #3 What the chuck!?
Stupid lathe question #3 What the chuck!?
So I finally got off the semi fossilized chuck off today so I could measure my spindle. Aside from a mountain of metal, plastic shavings, and sludge that came off with the chuck, I was slightly disappointed with what I discovered.
My spindle is 2"x 8 tpi. The largest adapter made by the Oneway folks is 1 1/2". What's my next option? Theoretically I can attach the chuck to the faceplate, right? How do I know if it will fit? Are there any standards to faceplates? What are my options here?
On a side note, I started dismantling the compound to clean it and found some fierce looking buildup. Is a wire brush something I should use to remove that or would I damage something?
Also is there anything in particular I should use to lightly lubricate the bed and the lead screw? Silicon? WD-40?
What the chuck, man. What the chuck...

The first cleaning on an old lathe is always fun
alright, so just a quick check...
Is your spindle 2" or 2-1/4"? Are you measuring from the top of thread to top of thread?
You probably will be into a face plate. Not super expensive. You're in luck, you already have a lathe so you can trim it for your chuck! You'll just need a plain back chuck if you want another chuck. So what kind of chuck came on it?

From the top of thread to top of thread it actually measured 1 15/16", granted, my calipers are not the best, no dial. A three jaw chuck came with it fastened on a back plate of the same diameter held on by three screws.
Re: Stupid lathe question #3 What the chuck!?
Since you have a metal lathe, and a nice looking one at that, you could make your own thread adaptor. You have 2 choices really, either a collar/stub that screws onto your current spindle nose and has a smaller suiatable thread on the other end, or (the option I would probably chose) get a blank end arbor of the same taper size as your headstock and cut the thread on that. Making either of these in situ on your lathe would provide a very accurate fitment for your chuck.

Did your chuck come off easily? My 3 jaw is stuck on like a beast.
Re: Stupid lathe question #3 What the chuck!?
How about a chuck with an adapter that simply chucks up in your existing chuck?

@ Chris: I have no clue really how to operate the more complex aspects of the lathe at this point. I think your suggestions, while completely logical and excellent solutions, are like asking a first grader (me) to paint the Mona Lisa.
@ UberHuberManBroDude: Yeah, it came off easily enough when I started turning it the right direction.
@Wayne: I have no clue what you mean. Are you saying mount the chuck onto the back plate, or mount a chuck in a chuck...seems a bit excessive.

Good thing is, you keep your 3-jaw chuck - which is perfect for stem work - and can simply chuck up a specialized chuck for briar blocks in that, and you can change between these with no effort.

Sure, why not ? The smaller chuck has a steel rod at its back side, which is chucked up perfectly tight in the bigger one ...

Unless I'm mistaken that pic is of Jeff Gracik's rig, which should lend some credibility to the idea.

It's as safe as anything else you will do on a lathe. The setup Jos posted is a Trent Rudat chuck on a Precision Matthews metal lathe. Nate King has the exact same setup. I've used it and it works beautifully. The added benefit is that the chuck can be used on pretty much any lathe as long as you have a decent existing chuck.Ocelot55 wrote:Wow, is that safe?

Re: Stupid lathe question #3 What the chuck!?
How hard can you clamp down on a piece of briar with this kind of chuck? THe thing that worries me when I see one is how far away the clamp point is from the scroll of the chuck which is doing all the work. Seems like it would bow out at the end of the jaws or put a lot of pressure on the chuck jaw slides.
