Teams With Mecanum Wheels

However... take a look at this. I think a shop with a nice mill, lathe, and tig welder can pop out four of these in 3 days. Or at least mine can

A short description of fabrication: Have a central hub with bearings that two aluminum plates bolt onto. Have slots milled into the outer parts of the plates. Slide 1/4" aluminum shaft, so it goes at 45 degrees (the milled slots do this automatically) and weld one side. Cut off extra with hack saw, repeat. At the end, mill the whole thing flat. Unbolt the side you didnt weld on, slip on the rollers, bolt back together, and poof! You have a mecanum wheel with very little effort.

Wow sorry for giving life to an old thread, but i saw your cad drawing for your mecanums veselin and was curious...without tons of machine experience are you sure your capable of milling 45degree holes? I've taken 3 yeras worth of machining and its not as easy as it looks. IDK, i dont know your abilities but seems like it would be easier to do it all like the ones which have been mentioned (IE 190's were amazing, they had the rollers supported in 2 spots unlike the conventional ones that only have the center bracket between both rollers) and 190's the only major machining would be to make round stock flat on 8 sides...seems a lot simpler to me
