I finally had some time today for more work. Got the rest of the HS-405 and -702 match-drilled, and clecoed the HS-710 and -714 in preparation for drilling all these parts, plus the HS-404 nose ribs, in assembly. I don’t have an angle drill, and was in a quandry about how best to drill these parts. Even though I measured everything precisely, I was also concerned about having the proper edge distance on all these parts when drilled together. Thanks to some advice from Jim Smith, I managed to get the job done with a 12-inch #30 bit – thanks, Jim!
Drilling is done – and the edge distances look ok. Closest margin is the HS-710 to -405 hole, where the edge distance is just slightly over 1/4″ from the hole center to the edge. The technique I used to lay out the center HS-404 and -405 holes seems to have worked well.
The goal for tomorrow is to finish match-drilling the entire HS left side, then fit the right HS frame to its skin.
