Wrappers Delight

Wire wrapping - got to love it!

This cross span on 1890s street consists of four wire wrappings. One at each pole and two more at the hanger. The wheelsets with the pointer help me locate the hanger position to the correct height and centering over the track.

The technique I'm using to install the overhead for my layout pretty much follows the technique detailed at the Trolleyville site: Hanging Simple Overhead Wire For Trolley Pole Use. I deviated a bit with the type of wire though:

Phosphor Bronze is a very good conductor of electrisicles, but there are some drawbacks with using this wire. Its more difficult to work with compared to magnet wire. Magnet wire is more flexible while the Phosphor Bronze is pretty stiff and easily penetrates the skin (my layout has literally been built with my sweat and blood!). Its tiny diameter looks real good, but hopefully this won't be an issue with carrying the DCC signals.

Nickel silver wire will be used for the contact wire since nickel silver is a very good material for transferring the electrisicles (just like nickel silver rails!).

I have also foregone the insulators for now, I have an innovative idea that I want to try out for that in the near future.

Alright, well... that's enough bloggerin' for now, I have a lot of wire wrapping to do. Yes sir! I have a LOT of wire wrapping to do.
