Not to be nit-picky or even discriminatory, but I'd imagine a team like your's would be able to machine that a lot better. Personally, to me, it looks like the edges could of been done a lot better, but I don't know if you intended it to be like that.

I'm sure a lot of teams thought about doing this at one point or another, I know my team did in particular. But we realized that you can get up the stairs perfectly fine with 6 12" pnuematic tires (each at a different height to compensate each other of course).
