Why not cast them in aluminum and drill/ream the holes? Ditch the bearings as they make the thing over-engineered and heavy.

Requires a bit of machine shop work, but with so much gear on ebay and craigslist, maybe a sponsor would donate cash or equipment. Go to them with a workable plan and lots of shops, because they need these skills, will help you teach and learn the skills.

It's truly the journey and the learning, not the cost.

Uhhh, bearings are important, don't ditch your bearings.

What keeps the tread on the wheel? Commercial wheels have a lip that captures the tread when two halves are brought together. (No bad feature for molded wheels, but requires lot more machining otherwise.) I assume you are thinking rivets at several places around the perimeter?

Exactly that, multiple rivets
