We have been implementing the shifting transmissions described in the seemingly very popular "Nothing But DeWalt's" whitepaper. While some of the instructions are a bit ambiguous (I'm a programmer, so I'm just passing this on), we've had no issues until now. Following the instructions to increase the bore size of the "carrier sun gear" (the one which attaches to the output shaft of the CIM) we sent said part to a machine shop (we didn't trust ourselves to do it, as the metal is so thin after this operation is completed). One of them came back just fine, but on the other the small portion of the sun carrier gear (what I suppose is the "sun") came clean off when the machinists tried to machine it. We're going to run the other one some time this week and see if it too fails, and we've ordered replacement parts to give it another go.

Has anyone else had this issue?
