Just ran across this vendor while searching for alternatives (including DIY) to Campbell's corrugated metal material. They're Rusty Stumps Scale Models. Here's the stuff:For years Campbell's has pretty much had a lock on this product. According to what I've read on-line, Rusty Stumps' stuff is just as good (the Campbell's material really is quite nice) but a lot cheaper. ($10.45 gets you 5-5x7" sheets.)
What really inspired this search is my ongoing quest for a way to make this stuff myself. Up to now the best attempts I found were done by such methods as gluing spaghetti together and using it as a mold to rub aluminum foil over. But today I found a clever new method that just might work:This guy uses the straight-knurled handles of tools (pin vise in his case) as patterns. I tried it with a piece of regular tinfoil, using a small screwdriver handle, and it worked great. Now to get some of that "heavy-duty" foil.
Of course, what I'd really like to have is the machine that Campbell's (and probably Rusty too) uses to make this stuff. I'm guessing that it's probably a pretty simple rolling press, probably hand-cranked that sits on a bench top.
