I've been messing around with the rims for a couple of years now, looking for ways to reuse them.
I think they would make nice smoke holes, and they are strong enough to be through bolted.
Yea, bike rims work for a center hub. This is my hub on a 15 foot yurt. I wanted to mount a small wind turbine on the shaft but never got around to it. I built it to take to festivals. It's been to Bonnaroo, Burning Man and a bunch of other festivals. My son commandeered the yurt and has been living in it off and on for the last 16 years.
