Got inspired while on a hike and decided to make a wagon wheel like they are actually built. 

Insert spokes (12) into the center hub then attach the outer wheel (6 pieces) to the spokes.

Slide on the “metal” ring to hold the outer wheel together. This should be snug.

Screw in the center shaft to the hub and leave equal amounts sticking out each side.

Then screw on the “metal” hubs.

Slide in the axle through the hub and screw on the hubcab.
