in the pic above you can see the table top for my newly acquired Craigslist find.
the problem is the the table hinges are froze in place .I used penetrating oil on the hinge and got it to move a little but it is still very hard to move and getting worse .I am scared the aluminum will brake if I continue working it back and forth .I also tried heat but no help there
any ideas ?
my next thing I am trying to do if find out how old the shopsmith is
here is a pic of the only number I can find

and my other question is do I have all that I need to do MORTISING ?
thanks for helping out the new guy
