What qualities does the wheel you linked have that the AndyMark mecanum wheels Eric linked to do not? The Andymark wheels are designed a bit differently with a single roller supported by plates on both ends instead of a two piece roller supported in the middle, but is there a specific reason this would affect your design?
Yeah, we were talking with AndyMark about producing our wheels from last year with them, but we didn’t really follow up after Atlanta. Not an easy process, but for the students it is a manufacturing process that many engineering students aren’t exposed to in college programs. This took weeks of our build season.

There are pictures of the process, we haven’t written up a process guide. We used Smooth-On urethane products and the customer support was terrific helping us through the process.
The binder clips held the wax models down while the mold cured. They wanted to float.
Thanks.
You’ve got the steps pretty well down. With the wax models be careful about temperature…we were really hot, which added air bubbles into the wax…and they took forever to cool off even with ice and a deep freezer handy.
