Anyway, the link belt is helped. And I guess for the price I paid, it's already pretty good.

Simon,

when you touch the top of the pulley with a bit of timber, while the DP is on ( be careful ), if there is a chatter sound, it's more likely the pulley itself is not machined or fitted properly. The chatter is no doubt worse when checked furthest from the center of the pulley.

I don't think a well machined pulley will cause any major problems if it is not perfectly in line with the other pulleys. The same could be said for the idler pulley if it is not securely mounted to the head of the DP.

Just the other day my new DP was replaced because of vibration, it was only a few weeks old. The company rep was surprised to see the vibration, I demanded a new DP as it should have been good from the start. I worked out that it had two problems, one belt was faulty and the motor pulley had a wobble. When I ran the DP without any belts attcahed, there was no vibration, it then occurred to me that whilst there is no load on the motor pulley , there is no vibration.
