Its not bad at all really.
We plan for the 2013 season to just buy .375" plate. Router out the shape and do the bore at the same time (not out the corners of the hex). Create a bolt flange pattern similar to the bolt pattern AM/IFI uses. And just rivet on 1/32 flanges out of polycarb or 1/16" polycarb.
Our biggest gripe is normally just getting the pulleys along with changing ratios down the road with belts. So having the ability to make whatever size pulley we want is awesome. I've contacted the FIRST gates rep about models before and they've been happy to send pdf's or coordinates of the belt/pulley profile. I'd love to just find a generator, but no luck so far.
