I have an older Shopsmith as well, [inherited from my grandfather]. I haven't had lots of use with it yet, but I'm a member in a couple forums.
http://groups.yahoo.com/group/SSusers/ For Shopsmith users; When I got the shopsmith I had tons of questions(since it wasn't running, and I wasn't sure what parts were for the shopsmith etc) and all my questions were answered quickly....like this forum.
