The wheels are a sandwich of aluminum and delrin plastic that I designed, while the rollers are 1.25" diameter EPDM rubber available for $.25 ea. from AndyMark. They roll on 1/8" diameter steel pins.
We cut the aluminum "bread" on a Haas 3-axis CNC mill and the delrin "meat" on our carbon-dioxide laser cutter.
There was no fantastic reason for us to build our own wheels aside from deciding to use an odd diameter for the wheels -- 5.75". I prefer to take the tread on the Skyway wheels down to a flat, 'slick' profile and, as a result, they're smaller than the nominal 6" original diameter.
Also, Akshay -- can you upload the pictures you took?
I think I have a warning label saved somewhere on my computer that says "Warning: All photos taken with this camera may be photoshopped" but I keep forgetting to put it on my camera. - MissInformation [more]
