Thanks John. Chris, I did try what you suggested with the folds, but the sections are too small to fold without the polybacker breaking. I can’t cut metals, non-ferrous or other on my CO2 laser. Fiber lasers can cut steel and other metals. After I posted this last night, I assembled a new version of the ladders, using acrylic, styrene, and brass wire. It’s the winner - easier to assemble, and sturdier. I have to dial in some of the measurements for the cut files still, and will post when I have these ladders on the car.
