craftsman 1942 scroll Saw

[sawdust255]

can anyone tell me why my 1942  craftsman scroll Saw keeps braking blades.

 It that old. I’d like to see a picture of it.  Just probably to tight on the blades try easing up a little.

Too much power. I'm so sorry for this answer. I truly thought someone was joking about their "old" saw. So, I was being my stupid self and putting forth a stupid answer. Very sorry for that.

Welcome to the forum Mike.   I hope you stay a while.   I don't think you will find a better bunch of folks.   I hope you like it here.

Welcome to the Village! Chances are you do not have enough tension on the blade. Blades need to have a high tension on them or they will flex when cutting. When they flex they will break. Your saw should have a way to tension the blade, usually with a knob or lever. If not, it will make a nice boat anchor. Can you post a picture of your saw or maybe a model number?

A big WELCOME from me. Don't know that saw but sounds like to much tension or pushing to hard or wrong blade for the job ie: thickness of wood . Roly

Many if not all of the old scroll saws used a spring to tension and pull the blade up, and a reciprocating mechanism to pull the blade down. If the blade jams in the work, the spring isn't sufficient to pull the blade back up. The reciprocating mechanism continues to push the blade up anyway, and buckles the blade, resulting in blade breakage. The newer style scroll saws have two powered arms, one moving each end of the blade, that work together to both pull and push the blade together, reducing the tendency of the blade to  bend or buckle. There is also a blade tension adjustment that truly maintains a constant tension of the blade.  This type of scroll saw was a total game changer over the old spring return type scroll saws. You can use much smaller blades with these newer saws and achieve long blade life with very little blade breakage.

That is a great answer. I think you nailed it
