Default Tablesaw problems again

My patch job on my Craftsman 113.298762 let loose. The pulleys started slipping again (maybe a little more than started) on both the motor and arbor. I've heard that machined pulleys are better than the stamped ones. Seems the screws and keys keep letting loose on me.

I like this saw, plus it's a bear to move out of the basement. Should I try it again or bite the bullet and go for a new one?

Is In Line Industries the place to go for these parts, or are there others??

I took the tests and retirement is the best job I'm suited for.

Now I know why old guys wear suspenders.

if its just the grub screws loosening, use some blue loctite on the thread and tighten a little bit harder.

install one screw on top of the other as lockdown......

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

If the motor has a lot of starting torque then that might be the problem. If the arbor doesn't have a keyway and the pulleys are gripping with only grub screws then I would drill a shallow hole where the grub screw goes on the shaft. Browning sheaves are much better than the cast potmetal ones and aren't that expensive in the sizes you need and single groove. https://motorsandcontrol.com/brands/...lleys-sheaves/

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

what is silcon?

Just looking at the In-Line site. According to them the motor has a 2 1/2" pulley and the arbor is a 2 1/4". The ones that failed were both 2 1/2". Does that make a difference?

Graingers has the good pulleys, Also don't use plated keys. If your pulley doesn't have a keyway...File a flat on the shaft for the set screw to set against. Using double set screws can lead to more problems than it solves.

Lots of cures suggested to try. If they don't work, get a new, better saw. I can imagne how frustrating an unreliable tool can be. Of course, what you get will depend a lot on your budget.

It's not so much the budget as the weight, Tom. I have to get it down the stairs into the basement.

Think I'll try one more fix. Then, it's time to "explore" alternatives. I got a portable contractor saw as a back up. Still got 25 custom orders to get out and a whole lot of squaring up and gluing to do, since Menards doesn't have any of my blanks in stock.
