On my initial bending brake set up, I had set the nos block to allow the bending angle to come just to 90 degrees before it bottomed out. The reason was that I wanted the bend to be forced against the nose block, and I assumed pushing the nose block out would control the bend the best. I knew this would mean I have to use an additional wedge to get the final 10 degress or so to account for spring back. Tonight I experimented with moving the nose block back far enough to allow the bending angle to over rotate enough to account for spring back without need for a wedge block. This meant drilling a bunch of new holes through 2 pieces of .25 thick steel (and wood) I ran a test part after completion and noted that the bend radius was unaffected by the set back and I was able to complete a full 90 degree bend in one operation. The radius checks at 0.156 which should be fine
