Re: Frame Perimeter Tolerance

I hope it never comes to this, but remember that the pits (especially the ones at Championship) can be rather toasty. Aluminum expands 12.3E-6 inches for every extra degree Fahrenheit. If your build space is rather cold like ours is (~60° F), and the pits are ~76° F, a 28x28 inch robot could gain 0.0220416 inches in its perimeter. That could cause you to fail inspection. Build smaller on purpose!
