A sample shot from the Pole-cam. Actually, it's not at all easy to visualize framing and focus when you're waving a camera around 12 feet above you. This is the only shot that's even remotely like what I was trying for. But I think it has some potential...
And yes, Vox was waving a metal pole next to power lines. Don't worry, I was well aware of the goofiness of that idea.
Example of a vintage asbestos-cement electrical insulator shield, labeled with stamped product part number. Why was asbestos used in such a material?
Asbestos was found to exhibit a wide range of physical properties and was naturally abundant, where it once gained increasing popularity and became known as the "magic mineral" in the world of industrial & manufacturing materials.
Certain types of asbestos minerals were found to possess tensile strength beyond that of steel, as well as having remarkable thermal stability, extraordinary thermal and electrical resistance, is chemically inert, and is non-flammable. It can be subdivided into countless fine fibers that are strong enough and flexible enough to be spun into materials that are a flame retardant and can be readily bound together with other superior insulating materials to create an enormous variety of "super-materials".

Cleaning glass insulators can be a challenge. We soak each insulator in a solution for 30 days before we hand wash each one. The extended soak time allows us to remove all dirt, rust, train smoke, & mineral deposits. After cleaning we hand polish each.
Ceramic insulators on a tree near the Cooper fountain. Overhead wires were removed years ago, but no one ever took the insulators down.
This was shot in mostly-foggy conditions (a little bit of sun breaking through), at full zoom, hand-held. I have never gotten this kind of sharpness in these conditions (or, indeed, in *any* conditions) with any other long zoom camera.
To get an impression of the quality, view the full-size image, at full resolution, and look at (a) the grain on the power pole, (b) the detail of the insulators.
I'm quite impressed!
Taken with an Argus SLR camera in week 493 of my 52 film cameras in 52 weeks project:

The film is expired Fuji Neopan 1600 (with the meter set to 800) developed in Rodinal 1:50 for 8 mins at 20 degrees.
This is a "Type A" ceramic insulator pot, as used extensively on UK railways. The photo was taken inside a blackout tent with the main light source (a studio flash) at the top. Strips of white fabric were placed just out of view in front to fill in the detail, and on both sides at the back to create the highlights.
