Jig for overhead wire poles

I've been reviewing the state of the layout, and realized that I've more-or-less got what I need to have a finished section of street-corner and a stretch along Ocean Boulevard - well, at least finished enough for some basic photos to see if the modules are developing the look I'm after. 

I want to have some overhead wire strung so any streetcar photos appear plausible. I've started work on the poles. I haven't got this down to a science yet, and I'm trying to pre-assemble as much as I can before installing components on the layout. 

The overhead wires aren't powered and are for decoration only. Each pole is made from 1/8" diameter styrene tube with a light cut from a Model Power highway light standard. The light brace is a slice of thin styrene. How the overhead wiring will be made hasn't been settled on yet, but I'll post notes here as things develop.
