(...) Hi Brian, If you're struggling with worm gaps for your leadscrew, this pic of my crane worm gearbox might help: (URL) worm is two worms long, plus two pairs of old type (crennellated) half bushes (small pulleys) and an old type 14-tooth bevel (...)

(...) That would make sense, but for the fact that the worm gear is ten years older than the gearbox that you cited. The only reason that the worm gear had to be made a tiny bit less than 2 studs long was so that when you put it between two TECHNIC (...)

Another way of putting it is that if you want to multiply align (stack) worm gears, the number of times the thread goes around the worm gear has to be an integer (or since (...)
