Drilling left HS

Two nights ago I continued working on the left HS. I clecoed the skin to the skeleton, marked the approximate hole locations on the inner ribs (HS-404 and HS-405) and fluted those two ribs. With the skin it really looks like an airplane part:

Today I drilled the HS-405 rib to the rear spar and then to the skin, and I also drilled the skin to the front spar:

When I prepared the junction of the HS-404 and HS-405 ribs with the front spar and the two front spar angles, I had to trim the HS-404 rib a bit more. Remember that I under-trimmed them to be safe with the edge distance? That was certainly the right decision -- thanks to all the other build log on the web for the heads up!

The two center holes came out fine and edge distance on the HS-404 isn't a problem at all:

I was still in a good mood when I started drilling the third hole, but then the drill wandered and ... I guess I'll support the US economy and get a new HS-405 rib.

The hole is too large to be saved, and I'm below edge distance anyhow. Will contact Van's tomorrow. Fortunately the front spar and the HS-810-1 are not damaged -- the markings on the spar are constrained to the area where the hole will be.
