Also, if you'd send your gearbox CAD file to mglucido@charter.net, it would be supremely appreciated!

All the best,

973 and many other teams vary their ream based on the fit they want. If they want a slip fit they will go with the exact bearing OD ream, if they want a press fit they will ream .001 under the OD. Reamers are a very worthwhile investment. The main bearing sizes used for FRC are R6 and R8, so you would want to get .874", .875", 1.124", and 1.125" reamers(we got from maritool, and maritool doesn't sell 1.124" reamers. Does anyone have a good source for reamers this size?)
