Thought that might pique some interest. It's not really that difficult, but it takes a little planning and a lot of time and patience. Gil's right - the jig is essential. It's really just a circle of card with another circle cut out of the middle of it and slits made around the perimeter. Monofilament is strung across the jig from one slit to the one directly opposite it for the spokes, capturing the hub in the center. The rim is made in two halves and they are glued to the spokes, then it's cut free from the jig and the tire added. There's one very important trick to doing it . . . . . As soon as I'm finished with this build - and the two wheels to go with it - I'm going to write up a step-by-step tutorial with pictures and diagrams. It'll be a few weeks, but I'll post it here when I get it all together.
