Matt,
Looking forward to this.....an additional excuse to make something I can really use, and see some other niffty "devices."
I'm personally liking your second and third ribbon design...the coloring being different from most of what is seen.
My project will be a little device (kind of no-nonsense) that will allow me to quickly and (I'm hoping) accurately make multiples of the same size vehicle grab handles. The design should allow one to be able to slide wire through holes in the template, pull it taught (creating tight right angles), rough trim the length from the underside, and then finish trim with a "gauge" scribed on the tool's top or bottom.
I'll probably do the prototype (neat word huh?) out of plexiglass and perhaps the final out of aluminum or cold rolled steel (for longevity). And guessing I will have between 15 to 20 "sizes" that can be made; allowing most, if not all, common 1/35 sized handles to be made (I'll use measurements from my various kits [Artillery, tanks, wheeled-vehicles] to hopefully cover the basics).
Mike
