Puzzled - Scroll Saw Woodworking & Crafts Message Board

jockellis · 10-31-2009, 03:18 PM

Hi, I am not an expert woodworker nor do I play one on TV. But I inherited a green crinkle finish 15" Sears/Craftsman hobby scroll saw eight years ago and never had use for it until today. So I buy blades, get home, turn on saw...and nothing happens except motor hums. I Google scroll saws and see how one works. But this ancient beast seems to have no moving parts except the nylon connecting arm attached to the motor and it only rocks back and forth when the motor was taken off to test.

Me, again. I've partially taken this thing apart. There are two pressed metal shafts, one on the top arm and one along the lower part of the frame. They are connected by a spring at the far end from the blade. The top shaft is hinged so that the blade holder can go up and down. the bottom shaft is bolted to the frame at either end and has the motor with the offset connecting rod bearing between them. I don't see how it is supposed to move anything with both ends bolted securely.
Also, it appears that the blade should be about 3 inches in length instead of the 5" of the newer models. This thing doesn't tell where it was made so I'm guessing it was America in a time when everything was made here and products didn't need to have the country of manufacture listed on them.

There are some older saws that used 3" blades. Someone had a url where you can still get the 3" blades...
