Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Page 19. There's Benesh but I need more exact info about the shapes and dimensions!!! How big should be gap and overlap in Benesh. Also bending radius of the blade is changing. But HOW!!?? There has to be exact formulas or something so I can make blades for Benesh. Or should I just scale the pic, print it, bend sheet metal and be happy and shouldn't worry about numbers.Edited by MakeeK 2009-11-25
