Right-o, Dave. I need to get me to a Michael’s Artsy Craftsy… I think you’re right about this.
Must look up paper crimpers.
John: Have you considered annealing the soup cans before straightening? I’m going to try this as it will soften the steel and fire-blue and warp the steel, which ought to be a great base for making aged roofing. Got a can in the fireplace right now, soaking.
John: My experiment was fruitful, at least to me. While the entire can was softened and the coatings burned off, that section of my can in the fireplace that heated to a dull red (very close to non-magnetic) proved to be very ductile after air cooling. This actually made it more prone to wrinkling when I flattened it (simply by stepping on it) because it was that much softer in comparison to the sections of the can that only got a good scorching. When I can get my forge back up and running, I’ll the whole can to non magnetic and air cool. Should yield a very pliable and responsible corrugated building material. By the way, corrugated galvanized iron was invented in London in the 1820s. Had no idea it goes back so far!
Thanks guys for your compiliments, The roofing is aluminum cans ran through a crimper. Yes cooked in a grill. IMHO the metal cans would be harder to work with
plus I like to have control of the rusting factor. You guys sure brought forth some good ideas though.
Thanks Dennis
