Not a shop tool but it is a tool of sorts. I built the chute controls from a wiper motor and a generic actuator. Spent under $100 on EBAY. The dealer wanted about $1000 for these options. I used an 18 mm socket with the square drive cut off, and drilled out to 3/4" (after heating to de-temper) to couple the wiper motor. The rotator teeth did not go all the way around. I cut an extra nine teeth so it can rotate 360 to prevent damage. It was a fun project. Snow is forecasted for tomorrow. :D
