The wheel helps keep it from vibrating around the table a top gear
This is my first gear box it was inspired by Halhi 141's version Which is much more compact and better looking, But my most
favourite part of his is that it did not use any official LEGO Clutch gears! Mine is a four speed gear box with no reverse, not much else to say about it.
Please tell me what you think also please rate and comment =D
