One at a time, ten pieces, twenty-four bends per sheet. Hold the piece in a vise, bend, check angle, adjust. Mildly time consuming, to say the least. Still gotta make a spare for the right side...

Well, we're from Brazil, so shipping five or six of those from Indiana would be outrageous. Anyway, we're on a really tight budget this year and those wheels were practically free:

Aluminum sheet and laser cutting - free
Rollers - $ 0.80/pc
PVC bushings - free
Aluminum axle for the rollers - $ 5.34, enough for about twenty wheels
Bolts and nuts - $ 0.34/pair
Machining time - free; lots of students and mentors put lots of hours making the rollers, cutting and bending everything.

So, those four wheels in the pictures cost us around $60 dollars, less than one mecanum from AndyMark (and don't take me wrong, they're great).
