Cutting sheetmetal roofing material
I have about 250 sheets of used (in good condition) 26 gage roofing
material. They are all 16ft long and I will need to cut many to other lengths while adding a shop extention. I have tried tin snips and these cause distortion of the ridges and spreading of the ridge pattern, hence sheet width. Not much, but enough that I get a "fan-out" effect in the width. Also unable to fit tightly to the next upper sheets. I also tried cutting with an hand operated electric sheer as well and got similar results. Abrasive cut-off leaves a burr on the edges and I can to a lot using a hand grinder. Recipricating saw produces similar results. I'm told the "pros" use a sheer with a die that matches the corrigations. The best I could afford would be a treddle opportated squaring sheer and with our a die, I would get poor results due to flattening by the sheer blade. Are there any other methods that I should try.? Perhaps a saw blade for my skil saw?? Thanks, Steve |
