Here are the pictures I promised, all the gusseting was very necessary due to the massive torque of the drill + CIM motor. It had a tendency to pull the worm away from the gear and de-mesh the two. This had the cute effect of turning the worm into a downright end mill and shaving the teeth off the brass gear quite nicely. Also the center gear was made out of soft brass to be a sacrificial gear of sorts. This allowed the worm to mate itself very nicely with the gear, albeit, with a few chips in the bottom of the chassis after the first few runs with a fresh gear. With this setup we had to change the center gear about every competition and a half.
