Re: make vs. buy wheels
Depending on what equipment you have, it can be very costly and take large amounts of time to machine anything. My team doesn't have a mill or any other type of machining equipment. We either have to have a mentor machine custom things, or hope that a machine shop will donate machining. Thus, we don't have many machined parts on our bots.
If you have anything machined, you have to make spares as well. If you don't and one of your parts breaks, you're not in a good position.
