Can someone please explain what it takes to add reverse to a 3 speed gearbox. What I mean is, what does it take to make it's output change to reverse. An extension is usually used, please  tell me why. I realise that two gears meshed together spin in opposite directions. Somehow when I try to design one, it doesn't always change direction. What could I be doing wrong?
