Total cost not including the metal for the plates, is $101.8 all from Vex. Thats enough for 2 gearboxes. The only thing that doesnt include is the sprockets, which the WCP doesnt include either so its moot.

As for machining, at our school we have 9 lathes, 3 mills, a CNC, and students who know how to use all of them. During week 1, we have kids that are much more interested in machining then designing, so we can make these during down time, when we don't have a full robot designed yet.

I'm not writing them out, and if we run into trouble that will be option 1. But I think we could do it more efficiently, cheaper and more focused to our needs by doing it manually. Plus it will keep the students occupied week 1.

Also what 4 inch wheels actually fit the 1.25 inch output shaft? I'd love to know, so we could make ours even shorter if needed.
