// What I'm building
A Technic gearbox with six speeds. You shift through the gears to go from slow-and-strong to fast.
The instructions from my earlier version got lost, so I'm rebuilding it and figuring out the tricky parts myself.
Big decision coming up: stick shifter or sequential shifter?
Stick (H-pattern)
Move the stick to any gear you want, like a car.

Sequential
Click up or down one gear at a time, like a race bike.
