I finished drilling all the holes for the left side of the HS. Feels like an accomplishment because now all the parts are located and all holes are drilled. Only thing left is dimple, prime, and rivet together. And, I can repeat this for the right side. I trimmed flange off the front mid spar to clear the front spar supports. I removed the skin and drilled the final holes for the supports to the front spar. The left half of the frame and skin are done for now.
