Nope.  Worm gears are not an integral number of studs long.  They are • about 1/4
of a stud short.  Not enough for a small pulley (1/2 bushing).

I'd be very interested to know the reason why LEGO chose to make the worm gear
so short :-(

Yes, it seems rather odd. It really wouldn't have affected the design of
the gear at all. Just extend the spiral another fraction of an inch.
Simple, really.

If it's right that they're about 1/4 or 1/8 stud short, you ought to be
able to line up 4 of them and stick in a half bush.

(...) 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. (...) (21 years ago, 10-Oct-03, to lugnet.robotics)
