what id suggest is this if i were doing it again.
Make a 6 degree ali template with a 1/8" radius or put the 6 degree lines on your bench. bolt a block to the bench on one line...clamp another block to it...sit the L shape of the 710/714 on the bench...bend it to the 6 degree line...(have to go just a little past for spring back)
definitely dont use anything other than hardwood or aluminium to clamp the parts while bending and the main thing is get the bend in the right place...so the middle of the radius need to be in the middle of the bend.
The check those striffener parts as mine were over 6 degrees from the factory.
when you fabricate the 702 parts and you flatten the flange out it leaves those bits not perfectly flat....so work on that area....i found they will hold up the stiffeners slightly....I filed a few small areas flat but not near the rivet hole.
good luck i have spent far too much time on this part because my bends were not perfect at the start and i think needed to be very slightly further inboard. i bent in the right place but the wood i used was pine and i think crushed slightly leaving more of a curve than a nice 1/8" radius.
If it were not all match drilled id be replacing the parts and trying again. I figure I have not work hardened the 710/714 parts as i have not bent and re bent them...just a little tweaking....and a lot of HS's out there wont even have the stiffeners so i imagine strong enough.
