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.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
