something tells me that teams are more likely to have a punch then a waterjet... :rolleyes:

Good point. But 1/8 sheet metal bends really nice in a vise. You can also mill holes in it, thats if you now to do it right. So you do need a punch.

There's absolutely no way you can fabricate a swerve module out of sheetmetal by bending it in a vise--it needs to be very precise, far more than you can ever be by using such a method.

If you want to make some thing works. You can do. It may not look pretty, but it would work.

Just in case people are wondering why we would go with 1/4" plate rather than sheet metal, here are our reason: it's light enough, we get mass amounts of it for free, our CNC sponsor prefers doing machining on this plate, and it's quite strong for its use.
