@sheetmetalsamurai: This Old Sheet Metal Ruler Was a Calculator Before smartphones and calculators, sheet metal workers carried tools like this. This vintage Malco tinner’s rule, made back when Malco was in Minneapolis, has a circumference scale that lets you quickly convert diameter to circumference for laying out pipe and round fittings. Most people think it’s just a ruler—but it’s actually a trade-specific calculator that’s been helping sheet metal workers for generations. And that’s only the front side. The back has even more layout charts and formulas. That’s coming in Part 2. #fabrication #sheetmetal #hvac #tools #metalfabrication
Please do a video on the back of you haven't already. I so desperately need to learn this!

I got a question so I got a fence panel that has a slope at the top so right and left hight are different. And there are pickets running horizontal but at a 45° angle and I need to find how to cut the top picket hitting the slope angle and keeping the same spacing from the other pickets
