Balance of the load (wood) and if it isn't perfect, there will be vibration.
That is why we preform and cut round asap.

Our lathes are also weighted or heavy or both. Some are filled with
sand and others are with metal and stuff.

Take wood out and close the chuck firmly so a single item won't fling apart.
Then turn on the lathe and see if it wobbles.

I see two things to try.

1. take the chuck off and turn it on again - wobble - check bearings / level ...
2. The chuck may not be on square. Sounds strange, but a little bit of
wood in the threads can cant the chuck slightly. Also, if the chuck
does not fit cleanly and firmly against the spindle and fully thread on -
that is another source of wobble.

I just upgraded from a midi to a new Powermatic lathe and would like to hear
anyones recommendations for a chuck. I have heard a lot of good things about
the Oneway Stronghold and SuperNova 2 chucks. Is there any benefit of one
over the other? What about a Vicmarc?
Also, has anyone used the Barracuda chucks from Penn State? Getting a few
extra sets of jaws is nice, but only if the chuck is worth it.
Any advice is appreciated.
Thanks!
I have the Talon and like it. Paid about $50 more than what it is here

seems like a good price but for a limited time.

Best of luck whatever you decide.

I have the Oneway Talon and like it a lot. I use it one a old
shopsmith which is a light weight lathe. I'm not sure if the heavy
oneway stronghold which is twice the weight would help with damping
the vibration in the roughing out phase. I have been looking buying a
second one and wondered if a heavy chuck would help with the
vibration.
