So we did a little brainstorming to up the ante and came up with a plan to try to pour our own fully urethane wheel (not cut from a root vegetable). In our research, we tried not to rely too much on professional wheel-making videos, which would muddle our creative process, and instead focused on using the cheapest, most accessible methods possible.
After finding a polyurethane mixture of the right hardness (we went with 65D, about as hard as 101A, the hardest hardnesss that skate wheels come in) we got a silicone mold-making kit from our local arts and crafts store and went to work.
Mixing polyurethane turned out to be sketchier than we expected, but no one got poisoned, so peep our supply list below if you want to try our yourself. Just don’t sue us if you use these materials to make a sex toy of your own genitals and something goes wrong.
