Saws - Recent Questions, Troubleshooting & Support
When I start up my Craftsman 16 in variable speed scroll saw, it makes a noise/surges momentarily. Then it settles into the correct speed. Is this OK?
It would take an owner to confirm if your unit is normal. I say run it until it dies. Here is some background (but I can't explain the noise.)
The inernal device allowing the variable speed is a varrister (sp?) and may go bad, though totally broken is more likely as in any/many electrical things. The initial full-speed could help prevent a burnout, as my friend recommends for ceiling fans because of the 'strain' starting the fan at low speed (truth or fiction?) I have destroyed one sabar saw by depressing the switch slightly and hold it there while the blade was not moving. Lesson learned.
Actually, a varister has only 2 leads and therefor your speed controller must surely be a little squear block with several wires. Replaceable but I'd wait until it dies.

I cant get the blade to go in on craftsman reciprocating saw model 315.114270
Could be as simple as the blade is the wrong blade for the saw.
Naturally, compare the old and new blades. If you got the unit at a yard sale, the blades included may be the wrong type.
I am aware of 3 types. One has a L shape. One has a narrow top with kind of a collar/bulge near the top. The third has the same shape throughout like a popsicle-stick.
If your blade is type 3, you can file down or grind off part which gets inserted into the saw. This would be the middle of three dimensions meaning the side where the teeth are.
Option number 4; there is a stub stuck in the saw shaft. Can't put two objects in the same space, so you have a challage to get the old stub out. Pounding might work but maybe sawdust has semi-cemented it up there.
