I'm trying to help my cousin out via phone and email with his Shopsmith circa 1960. I really know nothing about these machines except what I've "googled." He is telling me that his "chuck is stuck." He's removed the set screw involved and has had no luck removing the chuck rendering it useless for other tasks. I'm waiting for some pics but I thought I'd ask the experts here on GTTalk to see if anyone has run into this issue and if anyone has some ideas on how to remove it.
