While all of this was going on I have been busy with the left wing skins, deburring, dimpling, re-dimpling, and prepping for final riveting. As of tonight all I have left to do is the leading edge skin dimples and I can start the process of riveting the left wing together. Finally.
Oh, one more thing. The instructions call for me to "bevel" the joint where the two upper wing skins overlap at the point where they butt up against the fuel tank. I kept looking at this wondering how I was going to get this to look decent using a hand file. So I decided to see how other builders had done it and I found a few people who had actually trimmed the inner skin a little and then beveled the aft part of the rest of the overlap area. I did that and you can see the result in the pictures below.

|The pencil marks are last nights marks for the same temperature. Tonight when I made the call that the test was completed with no leaks the temperature was 81 degrees and the level in my manometer was at the 81 degree mark from last night.|
