I clecoed the leading edge to the right wing today. Before doing that, I upsized the hole that is predrilled in the bottom side of the skin for the tiedown location. After doing that and mounting the leading edge, I realized that apparently the predrilled hole was off. The hole I had drilled with the unibit was off-center by a significant amount. It's an irritation for sure, but thankfully I was able to make the hole line up to the tiedown bracket well enough by increasing the diameter by about 1/16".
Next step was to start on the stiffeners for the ailerons. There are a lot of these things! I'm going to build both ailerons at the same time - things seem to go a lot faster this way. Since I've fabricated stiffeners before. this time it went much, much faster. When I did it before, I was very exacting about marking and cutting the stiffeners to exact sizes. It turns out that exact dimensions for these really don't really matter.
After quite a while behind the bandsaw, belt sander, and scotch brite wheel, I had all of the stiffeners done.
