I bent the right longeron, match-drilled the F-721B aft decks, and made the downward bend in both longerons. Again, not a big deal--longerons are done.
 | The left longeron was done last night, waiting on his buddy. |
 | There, both longerons are bent, except for the downward bend. |
 | Line up the left F-721B to the 28 14" mark, and make sure that it sticks out by the thickness of a piece of .032", then drill it. |
 | Left is done. |
 | Both are done. |
 | Just a few wacks, and the downward bend is done on the left longeron. |
 | Bad view from the other side. |
 | The right longeron is done, also, except for the twist. |
 | Now, the twist. This is what you are trying to match on the fire wall. |
 | The bigger picture. |
 | One way to measure the twist--ruler on the right, behind the level. |
 | Here's another, the angle should be 17°. |
