General Signals - an excellent
source for replacement signal lenses. Online Metals - an excellent
source for sheet aluminum for backgrounds and visors. Call to place an order, as the online
prices are far too high for larger sheets.
Rayvern Lighting Supply- an excellent
source for color light signal bulbs.
I ordered a couple of dozen for about $1.50 each and they work great
even though they are not official signal bulbs and a bit smaller in
diameter. Ask for bulb SR 93. These are single contact bayonet S-8 shape
with a C-6 filament. They are 12.8
volt, 1.04 amp bulbs. Safetran Systems - check out their rear
serviceable color light signal and their state of the art fiber optic
searchlight signal located on their products pages. Union Switch and Signal - some information
on signals. Also could be source for
small replacement parts. Trans-Lite, Inc. Other Interesting
Signal Sites Special thanks to
Brian McMahon for photographs of US&S H-5 signal and stacked ground
mounted signal. |
Photos below. Color light signal background and searchlight visor I fabricated from sheet aluminum. For the background I used .090 inch thickness temper 5052. Because this is very difficult to bend, I used .065 inch thickness temper 5052 for the visor. Avoid temper 6061 as it is a harder grade which makes cutting difficult and bending probably impossible without machinery. To cut, I use a nail to scratch an outline of the final shape, then, with a saber saw equipped with a metal cutting blade, I cut as close as possible to the outside of the line. To obtain the final shape, I use a file to remove the excess metal down to the scratched line. To finish, I sand the edges with 400 grit sand paper, remove scratches with 0000 grade steel wool and prime and paint with Krylon gray primer and black semi-flat spray paints.
