Then don't answer!

The see Andy's anwser -- I have not yet read it, but I know Andy and I suppose you will be fine with what he recommends.

P.S. The addendum and dedendum of standard (i.e. off the shelf) gears is typically 1/DP and 1.2-1.25/DP This means the standard pitch dia is NOT the average of the Root Dia and the O.D. For the record, In FIRST, I almost always add a few thousandths to the theoretical center distance. extra backlash will almost never kill you in FIRST. Jamming the gears together because the gears are a bit out of round will eat up your power like opening the frig on a hot summer day.
