Nice!

Are those arms 3D printed?  If yes, you could print them in transparent green (or clear) resin, then paint just the arm brown, leaving the insulators transparent for very realistic look.  Back few years when 3D printing was new, we had someone do that, and it looked very good.

@rodsup9000 . It was just the crossarms. Artwork was drawn by @Mark W . Rodney gave me a set of the crossarms to try, and once painted like you said, they looked great on the round toothpicks I used for poles. Problem was they were incredibly brittle. Breath on 'em wrong and they broke. Well, not really, but brush against them even lightly in normal layout maintenance and, yeah, then.

My roundtuit is drawing my own version and printing them in one of the newer resins that are a little more robust.

Modular Railroading on YOU TUBE says that in this video, tried them and they were too brittle.

More work on Shaw's Cove.  The center pedestal was too short by .060", so I modified the digital model and reprinted.  The center pier also is too tall by .185", so I will be mounting a dental cutting disk in the milling machine tomorrow to shave off the excess height.

I am impressed with this model. I can't think of anywhere in the Great Southland where we have anything like this so I am watching with interest. To get close and find one part is too short and the other too tall would be a real PITA. But it seems to be all in hand to rectify. Will look forward to seeing this completed.

JohnB:  Such pictures of giant produce/fish/etc used to be common advertising, usually done with Lionel or American Flyer cars, some of the later ones on HO.

tried them and they were too brittle.
I have been mixing Voxelab Clear with Onyx Impact Plus (80-20) for a smokey clear color, and it's quite robust--flexible.  This mix would probably work with Voxelab green which is translucent and be the perfect color for insulators.

I did a bunch of prints of T-scale PRR Parlor Cars this week putting together kits and instruction sheets since a few will be on consignment at Fusion Scale Hobbies soon.

Finished model.  I have T scale Commonwealth trucks, but this kit is designed to be easy and just fit on the adjustable chassis.

Working on a more realistic coal silo for the Green Goblin mine.  I'm using elastic thread, sort of like clear vinyl, for the seams.  I was able to cut evenly spaced kerfs using 1x2 Legos as stops, but I wish the Chopper table was a lot longer.  Still have to figure out a way to get the bands on the front of the silo as evenly spaced as they are on the back.  Then dullcoat to glue them in place and hope the paint will stick.

Yeah, I initially measured for the center pier off the bottom of the bridge deck girders, forgetting that the side girders of the eventual truss bridge cage extend below the deck girders. The center column height was just a careless error.

If that is self adhesive vinyl tape, I like to warn you about possible material shrinking and/or adhesive getting gooey and possibly oozing out of the edges.  It could take several years for this to happen, but you might also get lucky.  I would not use  soft vinyl for any type of permanent construction.  Then as you mentioned, there is the paint adhesion problem.  IMO, you are still not too far into the construction to possible change the materials you use.

For example, I have experienced shrinkage of the vinyl Contac Paper, and even some electrical tapes.
