How much does it weigh? Not really sure, it is waterjet cut from 1/4" 6061. The bearing holes were reamed after the waterjet to get them to the final tolerance, however the real version is laser cut an right on the money. The intent with the box above was to have the capability of the drill spinning the same direction in both gearbox (One side had an additional reversing gear as you can see from the bearing cutouts) then through the shifter and into a hex bore. The drive module then has a telescoping hex shaft that slides in. The encoder is mounted in the gearbox and picks up the output of the 60tooth gear on the output. A servo lays flat above the CIM motor and manipulates the paddle shift. The final version is lighter in the plates with the same weight in the gears (which are all lightened) Pics next week.
