I used skateboard wheels, screwed into threaded rod coupling nuts that I silver brazed onto 1/2 in. hex bolts, that I screwed into a 1/2 in. threaded rod coupling nut. I cut off the kick stand attachment plate and brazed on a thicker plate and brazed the 1/2 in. threaded rod coupling nut onto that. One skateboard wheel screws into the top of the coupling nut and the other screws into the bottom of the coupling nut allowing me to adjust the height of the rollers.

I turned down the skateboard wheels by mounting them on a drill press and cutting them just like you would on a wood lathe.
