Yesterday I tapered the ends of HS-81-1 and HS-814-1 reinforcement angles. It took a while, but I first ground them down, then took the scotchbrite wheel to them for the finer details and getting that 1/4" radius. The bending process the pretty easy. I used a cardboard template for the 6 degrees, and placed them one at a time in the vise between a couple 2X4's. There was no mallet needed as I just pushed them by hand. Voila! Not so bad
Today I bent the HS-702 tabs between 2X4's aswell. I found the handseamer wouldnt quite work in this situation. After sitter there thinking, why the hell can't I figure out why the reinforcement platees are not seating nicely with the spar tabs....... OOPS! I bent them the wrong way! ... First mistake and luckly is wasn't a bad one. I simply straightened the tab out and bent it at the appropriate angle the correct way. Build on! I dimpled and countersunk the required flush rivet positions on the front spar and reinforcement angles. I notched out the nose ribs using snips, scotchbrite wheel,, and files. I also prepped the ribs and fluted the flanges.
I'm leaving some deburring and tight places on the entire structure until I get some smaller files and I'm ready to dissassemble for priming, if I'm going that route.
