Adam,

Thanks for mentioning this. You got me interested in designing gearboxes, and I'm pleased at how accessible it is to create a gearbox design that only calls for custom side plates and COTS gears and shafts. I've spent a bunch of time playing with various gearbox designs this summer, and I also showed some students how to design gearboxes. It's really fun stuff. I'm also pleased at how easy it is to come up with a gearbox that's lighter than the standard Toughbox or Super Shifter. It's really cool that AndyMark sells their gearbox components individually to make this possible.

I think I also read a post that Art Dutra (Team 228) wrote about the same general concept, so thanks go out to him as well.

I noticed that the AndyMark gearboxes are designed with an extra 0.003" added to the center distances between gears. I'm curious whether teams typically add that extra clearance when designing custom gearboxes.
