I could be wrong but I thought that when you ground the jaws you used a ring that sat on the outside, not the inside - like you would when gripping a section of pipe from the inside. This way, the pressure from grinding is pushing against the ring and not the scroll.
I checked the results on my 3 jaw and found best results when tightening using the #2 pinion. On my friends lathe it is #1.
