The R-HYBRID series are variable-geometry plate rolls, which really operates more like a press brake than a traditional plate roll, making such extreme rolling possible. There is a wealth of information on this site and I can honestly say that this is a great site with a wealth of information on it. 39/64 = 0.609375 radius Luckily I was at the end where the switch was. I still cringe when I think of that and that was back in the 70s. 13/16 = 0.8125 metal sheet formulas template formula math cone volume calculator bucket physics conical tube development flat drawing mathematics templates fabrication making
