Virginia got her hair cut today. If you keep up with this blog, you should see the results in a few days.
We started and completed the second, and last, interconnecting crossover of the antenna switches. It seemed to take a long time, but, in retrospect, we spent at least two days on the first crossover because a lot of the preliminary work was done under shelter during a rainy day.
Here are some photos of today’s work, of an unusual TP holder and of a butterfly that landed by the antenna switches pad:
Paul is cutting one of the aluminum posts to support the crossover.
Jim welds an aluminum base on one of several posts.
Joel cut caps for Jim to weld onto the top of the posts.
Joel taps a mounting hole in each posts’ cap. Meanwhile, I am making the standoff insulator assemblies that are attached using the tapped holes.
Using the posts with insulators, the crossover is in its final position and Jim is silver soldering all the joints.
In a mens’ room hidden behind one of the transmitters resides this unique TP holder. Only a creative engineer would come up with something like this!!
This butterfly briefly landed near where we were working. I took this photo especially for our 11 year old granddaughter, Audrey, who raises butterflies and gives talks to the Nature Sleuths groups at Oxbow Park. It looks like it might be some kind of swallowtail — maybe Audrey knows? The plant that it has landed on is a pesky weed we called ‘black-jack’ in Swaziland. The flowers are pretty and belong to the aster family, but the seeds cling to your clothing and are tedious to remove — see http://en.wikipedia.org/wiki/Bidens_pilosa
