Steve Baker articulated the following piece of wisdom in his post at 12:24

The end of the helix on one worm gear lines up exactly with the start
of the helix on a second worm gear.  If the gears were a quarter stud
longer, they wouldn't have this useful property unless Lego also changed
the pitch of the helix.

I'm not sure I agree with that. It seems to me that if you made these worms
from one great long string, all you need to do is cut them wherever you
want a new one. The helii (is that a word?) would still line up. I don't
see why they couldn't just "cut them" an unth longer.

(...) The problem is that you would need a mold for each unique part that is cut. If the number of rotations/divided by the length does not give you length that is repeatable using quarter turns you need more than one mold. This is *not* good (very (...)

(...) Hmm...yes, now I see. Unless you owned sequential worms, it wouldn't fit. Thanks for clarifying. Now I see what Steve was driving at. ~Mike (...) (21 years ago, 10-Oct-03, to lugnet.robotics)

Hello everybody! Does anybody know, where I can get a good manual for the legorobot programming ind assembler? I need to know how to work with the rotating sensor and the IR from the RCX (not the IR sensor). Good would be something with Programming (...) (21 years ago, 10-Oct-03, to lugnet.robotics)
