[Al Skierkiewicz]

This material is aluminum with 1/4" holes. You can buy it from McMaster but look at the catalog closely to purchase holes the way you want them spaced. The material is not strong in and of itself, but when it is stretched across the sqaure tube chassis parts and riveted in place, it is like an aircraft skin. As Karl pointed out, zip ties make an excellent, cheap and light, mounting for electronic parts. Replacement of bad parts is easily accomplished in a few seconds. Not to mention that light can enter throught the material for working inside. Although the holes will never line up for all the parts, you can't beat this as a base as it makes a perfect way to tie wires and PWM cables down so they won't pull out/off connectors and push ons.
