As an offseason project I bought a few DeWalts and have been working on an updated NBD type transmission. My goal is to take the original idea but morph it into a direct drive system (similar to
this 1213 setup, but without removing the first stage of the DeWalt transmission). Long story short, I'm looking for a 15T spur gear/pinion with an 8mm bore and 2mm keyway so it can be mounted to the CIM shaft and plugged directly into the DeWalt tranny without modification.
Has anyone done this? If so, any suggestions, and in particular, who sells gears like this? SDP-SI seems to have the best selection, but they don't have exactly what I'm looking for. Also already checked: McMaster, Boston Gear, Small Parts, Martin Sprocket, Google, etc.
