For those of you that use one of these, tell me what is wrong. I just got a Tru center taper tool, and it does not cut true. It takes more off one side of the shaft than the other. I am using the bushing that the shaft just fits in. Why is it doing this? I have tried blade adjustments, and it still does the same thing. Whats the secret? I knew I should have just spend the money and got a woodchuck.
