| | | | Restating for clarity, (I hope) I think the issue is the + shaped central hole. If you mounted these worm gears on an axle which requires them to be mounted at 0 (180), 45, 90, and 135, then of course you can't turn the gears anywhich way to line up (...)

| | | | | I have given this question some thought in the past and I came up with a theory. First of all some gear geometry background. Lego gears have 8 teeth per Lego unit (aka stud) of pitch diameter, the effective diameter to where the gears mesh. Using (...) (21 years ago, 12-Oct-03, to lugnet.robotics)

| | | | | | (...) Very nice analysis! All seems perfectly logical to me! (...) The other problem is not having an axle long enough to put them on. So I connected them together with axles butting each other about halfway through each worm gear. And with 14 worm (...) (21 years ago, 12-Oct-03, to lugnet.robotics)

However, you could get away with eight if you have one side of the worm gear at 0, 90, 180 and 270 and the other at 45, 135, 225 and 315, you'd just need to turn around every other gear (...)
