The infamous 4 hole drilling exercise - this time on the right side of the HS. This one turned out pretty good as well. I don't think I mentioned previously that these 4 holes are predrilled to 3/32" or a #40 drill bit first, and then enlargened with a 1/8" or a #30 drill bit after that. So, between the the two sides, I had to drill these holes a total of 16 times before they were done.
THis pic is taken from the rear of the HS looking forward, which is exactly how I drilled the holes. Note the reference lines showing where the trimmed flange of the nose rib on the other side of the forward spar. Used the same process as in earlier posts working on the left side in order to ensure that holes were in the proper position to ensure correct edge distance.
