end of an S-shaped crank, made from 0.015 inch brass or steel
wire (3-4)..
To make construction, adjustment, and mounting easy, I
screwed a strip of black styrene onto a small wood block to
hold the assembly. Take the trimmed and shaped plastic fig-
ure, and cut its head off(!) using the thinnest saw blade you
can get. Otherwise a thick kerf will remove too much material.
The cut needs to be flat and level. I had to practice this a few
times before I got it right. Drill down from the center of the
neck through the torso with a #77 bit. This hole should exit the
bottom of the torso the same distance as the motor shaft cen-
ter to the outer can of the motor. Next, drill a #79 hole in the
center of the neck into the head. Then glue the torso onto the
top of the block-mounted plastic strip, which should protrude
above the wood just a tiny bit. I angled the torso so it would
“lean” towards the outside of the window (5-8).
