Brief Description: Bending the flang ends on PF-183 & PF183
In forming the PF-183 ends you drill through the corners were you are going to make your cuts for the flanges as this will help keep the cuts from continuing to run after you make the bends. Then you leave the top tab extending out and bend the next tab out away from the part 90 deg. The third tab is bend 90 deg up closing the end of the part as seen in the pictures.
