I am looking to replace a Talon chuck. (on a Jet 1236, with 1" X 8TPI threads) I get a good 30 thousanths of wobble with the chuck. I have removed, and reinstalled the adaptor a couple of times, and tried out different orientations, but it still wobbles. The adaptor spins true, so the problem is probably the interface between the adaptor and chuck. I bought the chuck about two years ago, and used it a couple of times for non critical spindle turning, and set it aside while I had some surgery. Now that I want to use it for accurate turning, I find that I am out of luck. (Should have stuck a dial indicator on it while it was still under warranty) It appears as though the threads on the adaptor are not indexed with the threads on the chuck.

I will go to a brand other than Oneway, and E-bay off all of the special jaws, but I won't stick somebody with the bum chuck. I will keep it around for turning "close enough" projects. I am looking for either a chuck that doesn't rely on an adaptor, or else a four jaw independent chuck. (Like a machinist's chuck) That way, I could adjust my piece to center. (Although it might be hard to setup an inside piece to center with that setup) Anybody make one of these for the Jet threads, or do I have to do major conversion work on a machinist's chuck to make it fit my Jet? (It might be worth the effort, as it would also work well as an offset chuck)

I appreciate any ideas on how to solve my wobbles. If somebody knows of a scroll chuck brand that really does run true, and has a good selection of jaws, I am interested in hearing about it. I can't afford to repeat an expensive mistake though. The next one has to work!

Thanks,

Dave

Have you tried putting a washer on the spindle before installing your Talon.

Several turners catalogs sell them Craft Supply has them on page 44 of their catalog.
They call them no-lock spindle washer.

I made my own out of wood, also some plastic had laying around.
 
I do use a washer, but the chuck is not exactly in line with the insert. The insert is true on the spindle.

I will try their service. Better to make the one I have already paid for work. Besides, I have a lot of jaws for it.

Thank you for the ideas,
Dave
 
I'm surprised you've got a problem with a oneway chuck. Could the jaws be mis-set? Does the chuck istelf wobble or is it just from the jaws out? I love my Oneways (I like my Nova's too). Anyway, the only chucks that are consistently better than oneway's are vicmarcs. Everything else is luck of the draw.

Now that I think of it, how much would you sell that old, wobbling chuck for? PM me if you're interested.

A different perspective

Maybe the chuck is good and the lathe is bad. Sounds like a reason to get a new lathe. (My wife wouldn't go for that logic either)
 
While waiting for help from OneWay, would try adding another washer, try running with two.

If that didn't work, would try removing the insert and install it again. Would make sure both hex bolts tighten down equally. You've probably done that the first time, still worth a shot.
 
The adaptor runs true on the lathe. The chuck body has a little wobble. I think it's where the body and adaptor meet. (Just my uneducated guess)

I would try to talk Cathie into a new lathe, but she'd want me to get rid of the old one first. Then we would have a well timed "household emergency" that would prevent me from buying a new one for a long time... I have her figured out almost as much as she has me figured out.

Thanks again for all of the help,
Dave
 
Yeah, I took the insert out again, and cleaned it out really well. I wiped out the pocket it fits into, and reinstalled it again. I was careful to get all three bolts the same. Not sure what's going on. with it.

It works fine for basic spindle turning, and for making lace bobbins, drop spindles and the like. It just gets bad when I reverse chuck something, and I need the outside to be concentric with the inside. All of my turkey call pots have one thick side and one thin side!

Thanks again,
Dave
 
Now that I think of it, most (if not all) the wobble problems I've had with chucks comes from not getting the jaws to sit absolutely flush. I'd make sure they were seated and if that doesn't solve the problem then turn the jaws flush. And try not to forget to mark the jaws so I put them back in the same places next time.

Are you sure it's not your jaws that are slightly misaligned to the chuck? Maybe that would result in the slight 'out of true'-ness you're experiencing...

Aside from all the advice mentioned , Woodcraft has the SuperNova 2 on sale this month for $145.95 .
 
You would chuck a chuck without calling them?

Have you tried the chuck on another lathe? I'd be very surprised if it was the chuck itself. I'd try a new adapter, then try 2 of the plastic washer spoken of (I use 2) then try it on another lathe. Oneway stuff is among the best made. I use Nova, but Oneway is hard to beat, and the factory wants people to keep saying that, so I'd give them a try before flying into a whole new system. You could just as easily have the same problems all over again.

Keep us posted,
Dale
 
Thanks everybody,

The jaws seem to be centered on the chuck, but I can't tell for sure until the chuck body spins true. I might go ahead and shell out the coin for another adaptor, just to see what happens. I really think it's the fit between the chuck and the adaptor. I took it off and cleaned things up again, and it still has just enough of a wobble to render it useless for precision work. I will probably keep it for holding stuff that doesn't really need to be that close, as it is a handy tool for that.

Still waiting for a reply from Oneway. I posted on their customer service.

Thanks agian,
Dave
 
Dave ..... just a friendly suggestion, CALL Oneway. They're tech support people are really helpful. As a matter of fact, I remember calling them once on a Friday afternoon and all the tech support people were gone. The lady answering the phone ended up telling me how to fix the problem I was having.

The jaws are numbered, right? I'm really with Andrew on this one. Call Oneway and talk with them. I'd be really interested in hearing what they say.

The talon jaws aren't numbered , at least not on my talon . They are grooved on two of the jaws , the groove limits the outward movement so they don't run off the chuck .

Another vote for calling them an speaking with CS .
