I did what you recommended and here is the result: no chatter. To be more detailed, the motor is NOT completely silent but the noise do not feel too bad, rather smooth. In any case I did not have a Teflon based lubricant and used a spray lubricant for electric motors and also rotated the copper/diamond tip. Then I used the truing tool and got a chatter free result. Tomorrow I'll do a more extensive testing. I did not do things in stages so I do not know if it is was the lubricant or the diamond tip to fix the problem. I sense that it was the lubricant since this morning I lubricated the shaft with Vaseline (did not know what else to use) and the chatter remained only in the 20% external part of the stone. The external part of the wheel is where the chatter marks where always more evident.
PS: You think I should ask for a new motor for the low noise? Furthermore, could you tell me which is a "Teflon based lubricant" that I should use? I also feel that the Nylon bushing are not too appropriate for a machine that all said and done cost $1000 and Tormek should think abouth an upgrade.
