I'm setting up my 1st wood shop (electric, acoustic and cabinet building) and looking to invest in quality tools on a shoestring budget. I'm going to check out this band saw tomorrow. I've heard that certain old tools were built better than new ones, but I'm not sure what to look for when evaluating a band saw of this vintage. "12 inch, newer tires, working well." What should I check for? I've heard a 14" is preferred, is a 12" too small for guitar building?
