Now those wheels are pretty cool!
I assume the knurled pieces have pins extending from each side, and fit into grooves (or bearings) in the frame plates somehow, with a cover plate screwed on like a sandwich, right?
What're you using for a spin bearing surface, a bronze sleeve, or commercial roller bearing? Is that a fixed pin with the bearing hidden inside the knurled piece, or a spinning pin with the bearing surface within the plate area?
Gee... It seems like a LOT of force on a LITTLE pin. What are the support pins made of, and how big are they to support that much weight? Did they bend on you?
