Tonight I bent the close-out tabs on the four elevator skins. Pretty much a no brainer.
I found that I got a better bend if I used the wood block (as the instructions suggest) and then went directly to a hand seamer to finish the bend. If you did that, the bends look awesome.
I tried using the flush rivet set as the instructions suggest, but all that did was create an un-even bend. Fortunately I only used this method on the bottom skins. The top skins look great!
