For O scale (1/43) I got a toothpaste squeezer from Amazon for about $10.00 and cut up beer and soda cans and run through the toothpaste squeezer. It makes perfect corrugated sheets. By the time you made one I will have made 50 or more. Cheers from eastern TN
This is EXACTLY what I need to do for my craft project and you showed me how. And even better you demonstrated how to do it with materials that are readily available to me. Thanks SO much.
I just paid 10 bucks on ebay for some painted cardboard metal roofing and I actually have sheet metal in my stock pile damit wish I saw this sooner it looks good
