the 16t gears meshed in pairs to mechanically connect the two sides of the
diff. The idler was locked to the diff housing using a 1 x 5 liftarm w/ crown
holes. I used bricks and technic plates to form the diff housing. Probably
could get quite a bit smaller using liftarms and various connectors and a more
compact way to lock the idler.

| (...) gears are nifty for things like this. I wish there was a smaller piece that could be used to lock them on... Actually I think there is. did you use a technic triangle in your diff housing? If so, you could stick a couple of the small offset (...) (23 years ago, 7-Sep-01, to lugnet.robotics)
