I recently picked up a drill press with a Jacobs chuck which mounts on a 33JT spindle taper. The chuck is in excellent condition other than that is has a raised score / galling about midway into the taper. I was able to dress the taper on the drill press spindle with a stone. Wondering how to go about dressing or recutting the taper socket in the chuck.
I've got a SB H10 lathe and a good 4 jaw chuck. Thinking that I'll need to press the locking collar off, strip the chuck down and rework the taper socket on the lathe, but how?
Lots of options have crossed my mind:
Find a 33JT reamer.
Use the spindle to adjust my taper attachment and re-turn the socket (not likely, as they would be reversed).
Turn and arbor to match spindle taper, and then use it and some grinding compound to dress the chuck.
Or should I just cough up the money and buy a new chuck? (kind of defeats the purpose of having a lathe..)
Any suggestions would be welcome.
Thanks,
John
