David,
I have been using the plastic coated wire since I got back into building around five or six years ago.
I believe it is only available in two diameters, 3/64th 1.2MM and 1/16th 1.6MM
I use some of this plastic coated wire on almost every build. I use it mostly for roll cages and nerf bars.
I use CA glue BSI Insta Cure on all the builds with no problem or failures. I've seen the same glue I use, on your work bench, on some of your photo's.
Feel free to correct me if I'm wrong on any of this.
Bob
