This is a first for team 1726; never before have we fabricated a custom gearbox. This one was made by several students today using some 1/8" aluminum (holes punched with a Rotex Punch) and 3/4" birch plywood as a standoff.
The FP motor has a stock pinion, and the other gear is the first stage reduction out of the plastic gearbox. Since this gear comes with a hex bore, we just had to turn down a hex shaft in the lathe to make it work. Total reduction is 4.5:1, so whatever it’s turning will be going pretty fast.
(By the way, if Andy Baker is reading this… when are you going to come out with some sort of fisher price spur gear box? A kit that came with just the sideplates, standoffs, bearings, and output shaft would be incredibly useful! If made right, it could interface with a stackerbox, too… and it would save us all this pesky manual labor )
