I'm looking to buy a 4 jaw chuck for my lathe.
I have a 10" lathe (Atlas 10X36) and an 8" 3 jaw chuck already

I'm Looking to add a 4 jaw and i'm wondering if there are advantages to
using a bigger chuck over a small one other than the Obvious of being
able to chuck up bigger work. and the Obvious Disadvantage in price.

Assuming i dont need to put anything over 6" in the chuck are there
other advantages to having a bigger chuck over a little one?

And anyone selling a 4 jaw that fits a 1 1/2" x 8 TPI threaded spindle?

Thanks all

Brent
