We recently ran across this article from Make Magazine about a Florida man who created his very own drill powered mini electric bike to help make ice and beer runs from his tugboat to the marina.
His search for a right-angle gearbox to allow the center-mounted drill to drive the rear wheel eventually led him to Torque Transmission. To read more about the drill-powered bike, and to get the instructions for building your own, click here.
The right- angle gearbox used in the project was the Torque Transmission RAB-1 right angle miter gearbox. The RAB-1 offer customers a couple of great benefits. First, the RAB-1 has a longer service life with less wear. Second, the RAB-1 has greater tooth-to-tooth contact and quieter operation.
