I recently picked up a Craftsman 150 drill press and overall its in great condition and works wonderfully. The belt it came with though was pretty rough, so I picked up a replacemement 44" kevlar belt. It has the swivel motor mount and a 1/2hp motor.
My problem is that the motor bounces like crazy. Check out the video to see what I mean. I read the manual and it doesn't say anything about a clip to hold it or any way to hold the plate in place after you tension it. I see that some of the later versions have a clip to prevent exactly this. Mine isn't missing any parts, according to the manual.
Any tips on how to prevent this? Right now I just use a ratchet strap to keep everything in place, but it's not a long term solution.
