Cut it on a 45 (so the top down view is pointy), use a heat gun to get it nice and gooey, and then smush it together using a piece of angle to keep it straight. We spun it up irresponsibly fast (tachometer said 3000 RPM on 8" diameter wheels), and never had a failure. Urethane belting does make some really interesting shapes when centripetal acceleration starts pushing it away from the pulleys though.
