delta table saw12/5/15
I recently purchased a delta unisaw and it has a slight vibration and can't for the life of me find where it's coming from.to make matters worse it doesn't do it all the time either.It's a 2002 year model and I bought it from a widow woman who's husband only used it occasionally and has set in her garage for1 1/2 or 2 yrs without no use Is there a chance I need new belts?
I have had the same problem at a Unisaw.. But always with the same combo blade and never with a plywood or Melamine or rip blade ;^)
Take the blade off. Run the saw. Does it vibrate? If no, it's possible it's the blade. If it does then loosen the belts and move them around. My saw seems to stop in the same area most of the time. So it's a good assumption the belts could have a worn in kink on all three in the same spot. Moving them around should reduce or eliminate the kink showing up at the same spot on all three belts at the same time.
Or just change the belts. Pretty simple and not that expensive.
Thanks for the input guys.I found the problem. Turns out the pulley on the motor was so loose that after I took the belts off the pulley slid off in my hand. I tightened up motor pulley and quite as a whisper now
That'll do it.
It would be a good idea to either put Loctite on the set screw or install another set screw on top of the first to prevent it from loosening again.
Good idea John .thanks
