I am just trying to fold over the edge. The panel is a Brookville that has the 90 degree lip already formed. This lip is 1 3/8" in length on the sides. They leave 3/8" extra to fold over the inner panel a full 180 degrees. As I mentioned in the original post, there is only 1 1/2" of space to work in along the edges of the panel due to the way the inner panel is stamped. I don't know if the tool Brian shows in his post will fit in this space. If this tool will fold the 3/8" of metal over as much as 90 degrees, I think I can hammer and dolly the remaining 90 degree bend as you would on a late style door skin. If someone that has used this tool can make a good guess as to whether there is room to use this tool I would appreciate it. Thanks for the replies
