I have an up coming project that would be easier done on a band saw. So I am in the process of looking for a used band saw. I have found a 12" Craftsman tilting head unit on Craigslist. I would like to know what I should check for when inspecting the unit. I know that many people do not like Craftsman machinery, but I don't want to discuss the merits of any particular unit, but rather things that would make or break the sale. For example I have head that the wheels should be checked for vertical alignment using a long straight edge.
