The cutter on my neck turning setup seems to cut with about 1/3 of the cutter edge. Kinda like the cutter shaft is off-center. I have taken it apart, cleaned it and looked at it very closely. It does the job but, I feel it should cut with the entire edge of the cutter not just a portion of it. With the cutter on the neck of a piece of brass I can lift it up to a light and I can clearly see light between the cutter edge and the brass except at one small area. Is they normal?
