2022-10-27 (Th) PoweredInlineSkatesRev2 Adding pulley to inline wheel

I bought a kit to upgrade a longboard to electric, but the designer made the parts for particular wheels, not inline skates. The kit included a pulley with a convex face to fit into the cavity of longboard wheels, but mine have a different geometry. It would be nearly impossible to align the pulley and wheel by hand, so I drafted a bushing that slotted into the matching washer (25.5 mm) and accepted a 5/16" (8 mm) bolt going through the wheel and bearings.

I produced a couple of the bushings on my laser cutter with 3 mm thick basswood sheets. I added bearings to the wheels, pushed a bolt through the center, stacked the bushings, and put the black metal washer over them. Everything fit snuggly.

I used the holey metal ring as a guide to drill a 5 mm hole, then installed a nut and bolt to hold it in place. I repeated this for the opposite side, then went around until I drilled all six holes. I tested the holes by placing the wheel on a drill and spinning it to see if there was a visible wobble between the edge of the wheel and the edge of the washer, but they seemed concentric!
