I still hadn't heard back from Vans re- tooling holes in the wrong spot on H-00005 ribs on the h/s, so I called as soon as they opened up.

Talked to Kevin in Builder Support and he told me basically that all I needed to do was position it with the .125 shims under the front spar and the 3/16" spacers (drill bits) under the rear spar and drill it. He said I could also find the chord line of the h/s and measure from that. He went on to say that I could check for for twist with a digital level etc, which I has already done. Basically the objective is just to make sure the chord of the h/s is parallel to the longerons

Also, he mentioned that later on if I didn't like where the incidence was set, I could easily change it by changing the thickness of the fwd shims.

While I had him on the phone, I verified that it didn't matter what I made those shims out of, because yesterday I discovered I only had enough AB-4 bar scraps to make one side, so I had made the other one out of a chunk of AA-6 that I had in my scrap bin. He confirmed that the alloy material is completely irrelevant as long as it was the right thickness.

I told him to please delete my email from the day before, or check it as responded to or whatever, but later on Gary emailed me back anyway and said that the H-00005 had been redesigned since that instruction was written, and that the tooling hole location had changed, and to just put the shims in and don't worry about it.

In the meantime, I couldn't let well enough alone, so I had spent a couple of hours crawling around this thing measuring from about a dozen different points, including marking a center line on the ribs with a micrometer to find the chord so I could confirm parallel to the aft deck/longerons and measuring from the bottom of the lightening holes to the deck.

With all this measuring, I was able to confirm the angle of incidence, and to make sure that it was level side to size etc.

Ultimately, I made myself feel a lot better with all this monkey motion, but it didn't really accomplish anything else, because they were right, I didn't need to do anything other than make sure it was positioned correctly with respect to the shims and it was spot on.

Back drilled though the vertical bars and aft spar to #30. after each hole, I sucked it down with a draw cleco. Once that was done, I up drilled to #21 from the aft side, using a drill cup to make sure the holes were perpendicular.

After each hole was brought up to #21, I reamed it to final size with a piloted reamer from the aft side, and snugged down a bolt before moving on to the next one.
