Has anyone found a good source for quality metal corrugated roofing?
Use copper sheeting. Cut it into strips about 2 inches wide (widths that will fit your gizmo) Clean the strips with wet/dry sandpaper, about 400 grit. Crank the strips through your gizmo, then turn them over and crank them through again. They will come out nice and flat and ready for the blackening chemical or you can leave them natural and they will turn blueish green. You can glue them down with silicon. Ralph Merrill
