I was going to say this solution is easy, but then I tried it. There are
only two shaft's in this example. As lego don't make don't make a 'double
width gear' You'd have to use four to make it in lego. All you'd need is
three normal 16 tooth gears and the fourth would have to be the one with the
hole that's free to spin. slip the driving ring piece (I have two from the
space shuttle) into the open side of the free wheeling gear and then attach
the driving ring to it's shaft utilizing a rubber band connected to a part
fixed to the shaft. This will mean the gear with the hole will exert a force
on one of the gears on the opposite shaft, combined with the forces from the
meshing of the third and fourth gears there wil be no play between the two
shaft's.
This only works for two shaft's at a time.

| (...) You can use those half beveled gears(with the recess) back to back as one gear, and one (maybe 2) crown gears as the gear on the other shaft. It depends on what the setup requires as of gear setup to work. Andy (...) (24 years ago, 4-Apr-01, to lugnet.robotics)
