useful contraction, it must be stretched. Loop a rubber band
through the air muscle. Then remove the first of the four 1"-long
screws securing the top plate. Place the looped ends of the rubber
band where the screw passes through the top plate. Replace the
screw, threading it through the looped ends and through the top
plate holes, and then secure it with a nut (see Figs. 16.23 and 16.24).

Pull back the air muscle until it’s fully extended. Mark the end of
the air muscle. Drill a hole on the mark, and place the machine
screw and nut there. Place the end loop of the air muscle over the
machine screw to hold the air muscle in an extended position (see
Fig. 16.25).
Now drill a small hole in the plastic section of the finger pull. The
small hole should line up with the front loop of the air muscle.
The hole must just be large enough to allow a double strand of
magnetic wire to pass through it. You can substitute bare 22-gauge
solid copper wire for magnetic wire.
