I've been doing a fair bit of drilling on the lathe lately and have run into some issues with the tailstock. Tonight I figured out what the issue is. When drilling the quill wants to turn in the tailstock but that is prevented by the set screw that rides in a slot cut into the top of the quill. However when using larger size drill bits, like 1/2" and bigger, there is a lot of torque and that causes the sides of the quill groove to distort where it contacts the set screw. Then it becomes almost impossible to get the quill to move because the distorted edge rubs against the tailstock housing. Today's project involved making a 1" diameter hole in some mild steel. I center drilled, then used 1/4" bit, then 1/2" bit then 7/8" bit and the rest was done by boring. The 7/8" bit really aggravated this matter and it was sharp.
This lathe is a King KC1022ML (identical to a Grizzly G0602).
Anyone have any ideas on how to fix this issue?
