Hello all,


    I am trying to build bend tables for the sheet metal (typ. .059" Stainless Measured) we bend. Our tables are accurate for angles 90 degrees and more but fail at acute angles. I have pressed 5" test pieces at 135 (so a 45 deg acute bend), 145, 100, and 90. We may have had bottoming trying to press the 145 but the 135 completely airbent. I have been using the bend works PDF to assist me but while it works wonders with 90 deg bends I'm having a real hard time with figuring out acute angles. I set up a sketch jig if you will to help me interpret the dimensions. Has anyone had any luck with this or know any good calcs that work on non 90 degree bends?


Thank you all so muchsketch jig.JPG
