By "forks" I assume the mean the aluminum wheel housings? I don't think bending will be a problem. Maybe its the angle but they're about 6 inches deep. 340 milled it for us out of 1/4 in. aluminum and it all fits together great, plus I stress tested it with my hands lol. Thanks for the kind words though.

Thanks Colin, it works great. It allows very tight turns and high speeds. We're currently working on programming our potentiometer, so everything should be ready to go come March 6.
