Building a coker wheel.

With all the advice I received on my last post I was wondering about building my own coker wheel. I’m thinking about the air foil and the unicycle.com cromo hub with a flange of 71mm or the Schwinn with a flange width of 79mm. The Schwinn says it take 35mm bearings instead of the 40mm on the cromo hub. I’m confused. Anybody have any experience building one of these?

If I knew I’d tell you.
