I bought an ancient Skil Saw for a few bucks, thinking that I was going to use it with a metal cutting blade to cut steel plate. (Obligatory metal content).
When I got it home and plugged it in, the blade spun, but slowly and it seemed to pick up speed gradually, kind of like a fan, not like circular saws that I was familiar with. Then I heard and smelled a "pop" in the cord near the saw, complete with a small burn hole in the cracked insulation. It tripped the GFI outlet it was plugged into, so my guess is that there was a short to ground in the cord.
The saw has an AC/DC motor, 12 amps, and is a model 825. My guess is that it is around 50 years old. It is massive and heavy. It has an 8 inch blade, which seemed unusual to me.
My question is what to do with it. If the only problem was the cord, that is not a big deal. I could visit my local repair depot and buy a cord and perhaps brushes. However, the way it wound up slowly made me think that there was another problem with it. I am not real enthused about messing around with it if it is not likely to work more or less right after a little work. What do you think? Should I throw it in the trash or give it away on Craigs list? Or should I invest a few more bucks in a cord and hope that solves the problem? I don't want to throw good money after bad, but perhaps I can get it working right without too much trouble.
I know a moderate amount about electricity, but am not familiar with troubleshooting motors. I do have a VOM, and know how to use it.
