The 3-jaw chuck has been on for at least a year.
I need to change chucks. It mounts on a taper
and is drawn in and pushed off with a threaded
collar. The taper is holding tight after beating
the spanner wrench for an hour with a BFH. I
even heated the collar. I'll try to get some
Kroil in there but it looks like a tough road.
Any ideas from someone familiar with a RP?

Here's a pix of one like mine.

I don't have a RP but why not pass a large bar in
from the
tailstock and clamp on it with the chuck. Then try
the bfh
that way? maybe..... :)
