*NOTE: If end-flare is a concern and a "finish pass" is desired, consider adding two more passes to this ten pass example. Pass #11 would unfold Bend #1 to approximately 86 degrees and pass #12 would re-form Bend #1 to the finished angle of 90 degrees. The use of this unfolding/re-forming method would improve angle and flare control.
