I had problems with a tubeless tire leaking around the rim. I sealed it with Marprox Sealer 1000 (AKA Scotch Grip 847). A couple years later I tried to replaced it with a new tire. The tire company (Goodyear) ripped it to shreds and finally used a disk sander to get the shreds loose. The new tire wouldn’t seal, so I ended up buying a used rim from them. . . 😆
I have had good luck making motor mounts out of the black urethane and elevator bolts. Elevator bolts are like carriage bolts only the heads are wider and flatter. . . 😉
