Hi, I am searching a 3 inch chuck with an 1 1/2-8tpi tread for my South Bend 9.
Under 100.-.
Would anyone know?
Where can I buy a 3inch chuck for SB
Re: Where can I buy a 3inch chuck for SB
If you can't find a chuck with a backplate, then find a 3" chuck with a flat back and get an adapter plate.
Best price on a backplate is going to be this one:

It's 4", but hey, it's going on a lathe that takes 4" stuff and turns it into 3" stuff, so that should be no problem.
Search the forum for threads on making backplates, study them before you start so you don't make the same mistake I made. My backplate thread is here:

I think you're going to have to go the plain back route. That's a pretty small chuck for a large with that spindle.

Too many things going on to bother listing them.
