 If you never reach out and experiment with different things, you will never have the courage to reach out again. It's only through experiments and experiences where we get to understand ourselves better. - Ken Leung [more] |

Re: Trouble: AndyMark Mecanum wheels
No I am suggesting just the hubs like Andy Mark supplies. I should mention we used 8 inch wheels which were the only ones available last year. No the hubs are not for use as side bolsters for strengthening but for alignment. Without the hub on one side you are relying the torque of the bolts to hold the wheels square and that when you assemble the rollers they will be equal length. What happens is as the wheels are used you get a racking motion as that non hub side floats back and forth (not supported by the shaft) and soon the nuts loosen and when you do a quick reversal of direction the inertia can twist the plates.
