For me at least, the answer is emphatically none.

I never said this was a particularly efficient way of making a gearbox. It does involve a lot of cutting and drilling and clamping. If you want easy, buy something off the shelf - there is a lot of good stuff out there. I have a lot of younger students who LOVE clamping and drilling with the drill press.
The intention is for teams without access to a CNC to be able to make "custom" gearboxes. This is primarily an idea for my team - we used to have access to a CNC mill via a local makerspace, but it went out of business. Students used to enjoy designing and fabricating the gearboxes themselves. By "custom" I mean that the students can design the gearbox and select from more gear ratios than what Vexpro, AM and WCP offer as COTS. And if they make a mistake or are unhappy with the first iterations, the gears can be swapped.
The way things generally work in cases like this is simple: if you know something, you can't say it. So keep in mind that if someone does say something, it usually means they don't know. - Alan Anderson [more]
