Good luck I'd love to see the finished product hopefully you'll post some pictures. I don't have any pictures of our modified wheels or our finished product but omni directional is deffinately a lot of fun.

Thanks for reviving the thread, Stud Man Dan.

I had been meaning to post some pictures. We did complete a holonomic drive train demonstrator, and used it as part of tutorials at St. Louis FRC Regional Fall Training Camp about a month ago. Total weight as driven was about 69 lb. Controllability on linoleum or carpet is excellent. Traction is not great, but may be adequate for a flat surface, offense-oriented game, and it should improve somewhat when weight is added.

I'll post some more pictures tonight. One shows the anti-binding washers (ersatz thrust bearings) that you described above -- we added them after I posted the picture that started this thread.
