After getting confirmation from Vans that there were no issues with the relief holes I started in the forward spar, I cut out the edge of the web with a band saw to open up the notch and smoothed and rounded out the edges with a file and sandpaper. I then trimmed the inboard ends of the front spar flanges per the drawings and flattened the remainder of the bend. It took me a while to figure out how much of the flange to remove because the drawing and instructions reference a rivet hole that is not already drilled in the spar. I ended up measuring the length of the cut on the plans and using that to make the cut. I bent the spar tabs to match the angle on the spar reinforcement and splice angles and then countersank the angles and dimpled the spar where they meet in the middle. I finished up by notching the HS-00006 ribs to fit around the angles. I attached the skin to see how everything fit together.
