Craftsman 3 Jaw Chuck Problem....

You'd be better off buying a new 3 Jaw like I did.
I use the old one on my wood lathe now.

It was just a cheap import 3 jaw from eBay. $89 with reversible jaws.
Ordered the backing plate from Little Machine Shop for the 1 1/2 x 8 spindle and drilled and tapped it for the bolts.
Bolted it together then trued up the back plate with chuck on at real low speed.
Back plate is Cast iron so it cuts easy.
So far it has worked great with no problems and it is within .001 to .002.
Good enough for what I do on the lathe.
 
I appreciate all the response and advice/help. I guess I will muddle along till I find a set of jaws or a replacement Chuck. Thanks again Gents!
 
Some swarf jammed in the scroll plate? Had that happen on numerous occasions back in the machining days. Could just be something small stuck there or forced into the scroll thread, causes stiffness/complete stop in the jaws movement. Dismantle chuck, close inspection of inside may be all that's needed. DON'T lube with grease, very light oil if nothing at all, the stickier the lube, the more likely to gather more crap! Slippery, not sticky. (works fer change gears and the like too)
