Brief Description: match drill rib attach angles for center spar
I match-drilled and bolted on the first two rib attach angles on the center section spar carry-through. This was kind of a hassle, made unnecessarily difficult because I decided to drill the bolt holes during the rivet hole drilling step. I thought this would be a good Idea because I could use the bolts as additional clamps to hold the spar caps in place for rivet hole drilling. But now I have to take some extra pains to get the rib attach angles lined up on the holes and match drilled. The lesson learned is that anything that needs to be assemled together needs to be drilled together. So on the wing spars I will wait to drill the rib angle holes until they can be drilled with the angles clamped in place.
