Finished matchdrilling the firewall - 2 hours

So now that I have the word from Van’s that the edge distance at the top of the fire wall is not an issue. I was ready to start match drilling the firewall to the fuselage. I started drilling all the holes along the bottom of the fuse (top from my perspective). Then I started drilling the sides starting at the longerons as per the plans.

The edge distance at the top most hole ends up super close to the edge of the relief in the flange. Eeesh!


 The edge distance on the corner weldments are really good. The blue line represents minimum edge distance (to center of the hole) so lots of room to work with here.
