2:1 Gearbox PLANS (11-Speeds) {COMING THIS SPRING}

PLANS are for a 2:1 gearbox, but after we thought about it, why not make it 11 speeds AND driven by a servo motor.  Obviously only one mechanical speed at a time, but still capable of 11 different mechanical speeds.  The original need was for a 2:1 reduction to lower the speed on a NEMA 17 electic servo motor.  Most gearboxes have a fixed Pinion and Gear and have been designed to only hold those two gears.  Ours has room for tooth counts from 40 to 20.  Combining them on the same center distance gives 10 different speeds.  The 30:30 ratio is 1.000 which is useful as the shaft rotation will be reversed. THIS KIT REQUIRES MACHINING ALUMINUM AND STEEL - If you can mill, drill, bore and tap on a mill, and turn and groove on a lathe you can do this. THIS KIT includes a build sheet including specifications for all of the component parts The kit calls for 6061 Aluminum for the gearbox, 4 ball bearings help the 8mm shafts spin the gears with very little friction.  Two spur gears a 40T and a 2
