6-Speed and Reverse Gearbox

My attempt at a better gearbox than the Andreas Konkoly 9-speed and reverse gearbox.

The gear ratios are more useful at 12:1, 6:1, 4:1, 3:1, 2:1 and 1:1 in forwards and 12:1, 6:1 and 3:1 in reverse.

It also runs fairly freely.


I see you combined a small-ratio 3-speed-transmission with a 2+reverse range group.

My intention is to replace an existing 5+r by a 8+r, probably a 8+(4r) without producing more length. Of course not only as a Meccano model.
