How about a piece of brass tubing round or square with a small hole drilled in it where air could blow out and wig the wag. A small aquarium pump could provide the blow. If the wig-wag was on a fine piece of wire it would wag quite easily.
After FINALLY getting all the stuff necessary to build the lamps over the doorways, I fabricated the first one and installed it today. It came out pretty good!
Only five more to make!
This only took about three different orders to NGineering, plus three ebay orders for various LED packages. Once I finally had all the right parts, it only took a couple hours to make this first light.
Thanks to all for the various suggestions and links to supplies. They were essential to my success in getting this first lamp built and installed.
Once the other lights are done (and maybe one or two inside the building as well) you’ll be able to see the results in my layout build thread.
Nicely done, Mark!
