Hi Stephen,

this confused a number of people when I first posted the pictures (it is not my gearbox by the way).

Two gears on the set up shown will keep rotation the same, three will reverse it. The key in understanding this is to remember that the cable comes in from one direction and leaves from another - look at it this way and it will all become clear.

If you want to reverse using two gears you need input cable on one side and output cable on the other side of the box.

Thanks Ruairidh,
I will have to have a sleep and then rethink!

In on the left out on the right will reverse direction.

Or if you make the same gearbox with the input fitting on the rear plate and the same size gears (all else the same) then you will have a drive reversing box.
