New member / shopsmith owner to the board! I've had a MKV 500 for all of about 3 days now To be honest, I had never even heard of shopsmith (or paste wax) until I came across one on craigslist looking for other woodworking tools... and dove in!
Felt like I brought a piece of Americana home with me, and I'm as much excited to restore it as I am to make things with it.
I've been trawling through the helpful stickies / google drive files / whatever I can get my hands on to start it back up on some sort of maintenance track. Thus far I've lightly polished the upper tubes back to mildly acceptable, vacuumed & blown out any sawdust I could find, lubricated and ran the headstock through a few slow low-high cycles, and waxed the heck out of anything that I've busted any rust off of. It lives again!
That being said - I'm stuck. My Lathe Drive Center is darn near welded to the quill spindle. The set screw comes out no problem, and about 24 hours of letting PB Blast sit in the cavity has done nothing but make my hands smell. I used a rubber mallet to lightly tap the center from all directions trying to encourage the penetrant to get in there... I'm not sure the fluid level even changed.
I'm not sure if I should heat it up, soak it in some elaborate bath attachment, wrench on it, destroy the center with a bearing puller, yank the quill, or what. I looked and looked for similar situations, but each time it seemed to be a different attachment (i.e. the sanding disk / drill chuck/ etc.)
So needless to say - I'm stuck! Any suggestions?
