More Drilling; Forward Side Stiffener Brackets
Today I had only a couple of hours to work on the project. I went out and drilled the right side forward skin bend....I think it came out pretty well.
Then I decided that I really couldn't procrastinate any more on drilling the foward side-skin stiffener-to-firewall tabs. So, I made up new brackets and only drilled the holes that attach to the stiffener (drilled 'em to #40 as pilot holes then later drilled them to #30). I then clamped them in place and eyeballed the hole in the firewall and drilled from the inside out.
I still had no idea how I was going to drill the bracket to the stiffeners...
...but the answer was much, much simpler than I thought. I ended up unclecoing the forward skin along the longeron and the top-must (but on the bottom here since everything is upside down) clecoes on the firewall. I was able to peel the skin back and get a pretty much direct shot on the brackets. This picture looks like the long bit is going through the longeron, but it's actually passing between the longeron and the skin. Finding a simple solution to an interesting problem like this is satisfying, even if the workaround should've been obvious.
