So I am having a lot of the same issues that I see that other builders have had, but I wanted to run by a possible improvement for the way mine is turning out. I have riveted the forward frame hinges and center splice plate already, and it would seem that a hard to avoid error was introduced during that phase. The result is that the left and right sides of the skin are riding up 1/32-1/16" like has happened to many others. If I force the frame to sit lower so that those gaps are non-existent, the center of the frame pulls the skin down ~1/16". So my dilema is where to balance between these two extremes. Here is a picture with the frame pushed low enough to make the sides look good:

Now that I am ready to drill the actual hinge points, I think the best solution is to drill them with things pulled tight, and then add a 1/16" space between the skin and frame once I'm done to fix that. Does this sound like a good enough plan?

First make the frame fit where you want it, then shim the skin as necessary.

Thanks Mel, that is what I will do. I just needed a second opinion on this one.

Frame profile issues

I believe the frame contour is incorrect. Shimming is required in this area.
