Don (or anyone else),

Have you done this before (i.e. turned down the BB output shaft to the diameter of the CIM pinion bore, and then milled the keyway in)? I was discussing a BaneBots to Toughbox last night, and wasn't sure what teams have done before. I imagine turning down the hardened shaft would be a royal pain.
