Notice my rivet orientation on the this (Left) Spar -- The shop head is on the thicker aluminum angle, and the manufactured head is on the thinner, aluminum web. In this pic we are looking at the Aft / Flush side of the spar, and if comparing to the Right Spar, this rivet orientation is different (the web arrangements are different on the Left & Right Spars).
I read that it is "standard practice" to place the manufactured head on the thinner piece when possible. I did not see a reason why I could not go ahead and do this for the middle and outter parts of this spar, so I did. I was not able to completly finish the outer spar because of this... |
