Tim,
Thanks for looking and your nice comments. I really appreciate it. I never mind sharing any technique on this board, since I have personally learned so much from here. With what I have learned just from your builds alone, I owe you a few!
John Teresi, a true mentor to me, gave me some really cool data circuit tape a few years back to do some pinstriping. But it also works great for zip ties, etc. I have two thicknesses, and I use the thinner, but I don't recall what the actual thickness is. Being that the other is .040, it's less than that! Here's a pic of the tape:
I was just rolling it around, but I found I had trouble with the stick glue would come undone and it was awkward to try to glue it. So now I just stick it to itself, trim it, then glue the tab down. Here's my best effort at a Ken Hamilton-esque drawing, which should be self explanatory.
