i. Mount end support A rigidly to bottom plate D.
2. Mount end support B on slide F which moves between guides G-G'.
3. Drill holes C-C' co-linear to fit insert tube (ca 8mm OD). Enlarge
hole C to fit coax plug. Fit each hole with an end plate.
~. Side posts E-E', mounted rigidly to D opposite the coil, serve as
(a) tie points for the coil and (b) terminus points for the
tension springs H-H' which hold the insert assembly in place.
~. Space posts E-E' far enough apart so that a length of wire a' = a
can be secured to each side . Then when the rubber bands are cut
loose the leads will be free of kinks.
6. The scale is about one-half~ the overall length is about i~ cm. and
the dimmensions are not critical. The materigl is wood.
