Gene, Unfortunately my fathers log books (which
included photos of nearly
every harness (type) he ever built as well as an 8mm movie showing
construction of one over time, were lost/destroyed about 15 years ago
[apparently "climate controlled" on a storage unit does not exclude over 2
feet of water on the floor during spring melt....
Damn. I would've loved to have seen that.
The typical method was to design the harness
(schematically) and then create
a blue print [I love the smell of ammonia!] at 1-1 size. This print would
then be adfixed to a board (typically plywood). "Nails" would be driven
through the blueprint into the board at all corners, angles, junctions, etc.
I might be able to do something similar by drawing the wiring layout on
some kraft paper taped to a plywood base. What kind of spring would be
used? I suspect you'd go after one with enough turns to hold all the
wire, but at some point you'd end up with a huge "fan" of wires if the
spring wire diameter were too great.
