I have a j head clone with a change belt set up. I sometimes get a noise that sounds like a backlash vibration. If I loosen the belt some it goes away, but there is no play in the bearings. The pulley to spindle has a small amount of play, not much but some backlash. I seem to here the noise more when using a heavy tool, large chuck, facing mill ect. I have not heard the noise if I run in low range. If I leave more slack in the belt it runs very quite. Sometimes it makes the noise while cutting sometimes while spinning free. Any ideas?
