bending angled pieces

[e_mike]

I am starting to do a 5 sided light. I know all the inside angles are 72 deg. each vertical piece will we bent to this angle to form the corners then swaged out to meat the bottom frame (i want the inside of the verticals flush with the bottom frame.

my question is how do i bend the curl at the bottom across the 72deg angle and still keep the angle (think curling angle iron along the corner)

I would split the middle of the curve curl to the desired point and remove the excess material that will be at the split.

I would think that if you make a jig where you could slip the end of the angle in and wrap it around.. Like a typical scrolling jig but the contact edge would have that 72 deg angle on it. Just bend and hammer it to hold the angle? (Beware, I have not done any scrolling so this is just off the top of my head.. or perhaps near the middle.. somewhere in there.)
