Figure 3 is a side view, showing the attachment of the elastic band. The
bolts, nuts and washers used are size 4-40 American National/UNC (similar
to 6 BA or M3 - approx. 3mm).

This is my first attempt, and other variations are possible. The actuator
bar could be triangular or T-shaped, allowing the device to be attached
parallel to the track rather than at right angles. It could alternatively
be installed the other way up, attached directly to the baseboard, as long
as clearance is provided for the 2 bolts passing through the base.
I would welcome any comments or suggestions on how this turnout actuator
might be further improved.
