Holy bucking Broncos Batman...!
I was using the tablesaw yesterday with a dado blade installed and a cradle attached to the mitre slide when all of a sudden the whole thing started jumping around like a rodeo event! I didn't want to let go of the part cut workpiece so I found the big red button with my knee and every thing calmed down pretty quickly. My first thought was that the dado stack had come loose but a quick check showed that one of the drive belts had failed and the second was already partly shredded!
I got 2 replacement belts from from auto cheap and I couldn't believe how much smoother and quieter the saw was after fitting them! Obviously the saw had been trying to tell me but I hadn't been listening.
Fletty
