 Conclusion: even though it cracked, it did not fail catastrophically, and this is with a stress much higher than it should see in the proposed setup. Even assuming a ton on each side, and if only 1 square inch of the wedge takes all of the weight, I feel it would still be lower stress than the test by at least a factor of four.\\ Conclusion: even though it cracked, it did not fail catastrophically, and this is with a stress much higher than it should see in the proposed setup.

-The UHMW is probably more likely to fail, though even if it smooshes or splits a bit it might still let us do what we want. But, is there another option that we could look at? If we have to use something a little thicker (say, 1/8" fiber-reinforced UHMW such as the "high-strength UHMW" on https://www.mcmaster.com/#uhmw-polyethylene-sheets/=1bttgqn) we might need to raise it up a fraction of an inche, which should not be a problem.+The UHMW is probably more likely to fail, though even if it smooshes or splits a bit it might still let us do what we want.
