I just got a "free" South Bend 9A. "Free" because it needs a tailstock, a toolpost, and some serious work in the quick-change gearbox. Luckily, my brother is a machinist and can make me new gears. The problem is that I cannot get the cross-slide free. It's a non-taper-attachment model, so the lead-screw nut is made such that I can't just take the screw out of it and try to slide it out. So I have to unscrew it or slide it out by taking off the dial and bushing. Unfortunately, the lead-screw is solid stuck. Like it's welded! I did manage to get the crank and dial off, and the cross-slide itself is loose on the saddle, but I haven't managed to get the bushing off of the cross-slide casting. It is very solid in there. I think that's where the lead-screw is stuck; maybe corroded in there. Any suggestions on ways to loosen up the lead-screw in the bushing and cross-slide casting? I've been putting Liquid Wrench in it, so I'll see what happens tomorrow, and if that doesn't work, is a torch a good idea?
