AndyMark Nano Break In

To the inside of the casing on the output shaft, correct? We have the hex output shafts, and I'm thinking that we will wind up doing this. Finding spacers for a hex shaft is a pain; the closest one I can find is on sdp-si.com and it's $13.00 for a 3" length. We could go with oversided fender washers, but I'm afraid that they'll rub the outside of the bearing, thus making the whole thing inefficient. So Andy, when you read this, perhaps that's a viable part for next year (Aluminum spacer for 1/2" and 3/8" hex shafts, either a rod stock or individual spacers).

As for the variable burn-in issue, I would presume that it's the CIM gear that's the issue. We found that 2 of the 4 CIM pinions in this year's KOP do not mesh well with the other gears; one downright gets stuck if you let it free-roll. Thus we swapped to a previous year's pinion for the burn in. In the offseason we may experiment with fixing the gears by filing them down a hair.

If you make 10,000 parts, some of them are bound to be bad
