Why is my tablesaw whining?
My son had a Craftsman 10” saw that the shiv or pulley connection to the shaft was loose. It would spin up but was noisy and when he tried to cut the blade stopped. I checked it out and the set screw had backed off a bit and it did damage the shaft because he had tightened the belt and it worked for a while before he called. I tightened the set screw on the shaft the shaft to pulley or shiv is not perfect because of the spinning damage but with the screw tight it works fine.
