Distractions
We would have riveted more last night, but Adam wanted to cruise the airport a little in our vintage golf cart (73 Harley model D gas). We came upon a couple avengers in the neighborhood, wings folded and engines running. Waited to see them depart. The local RV squadron did a formation departure too.

Re: Heat and aluminum
One chart I looked up says that either the tensile ultimate or yield strength does not change at 350F for less than 6 minutes on temperature, or for 300F at less than 30 minutes. Ageing temperature for bringing the material to the T6 condition is 320F. I have belt sanded a lot of edges, and I don't ...

Re: Heat and aluminum
Tony,
Either annealing or changing temper of aluminum generally requires temps in excess of 500F. I have friends at work who can more definitively answer the question for 6061-T6. I will get back to you. I think you are fine however.

Re: Cotton Waiex 191 - N191YX
I assembled the left hand side with similar results. This time I was careful to take the springback out of the flanges, so the bottoms were 90 and the tops matched the angle of the front spar in the plans. I did not think that would make a difference for a dry fit, as on the right side the clecoes w...

Re: Cotton Waiex 191 - N191YX
Trial assembly of right stab. Root rib seems too short though it measures up right.

Re: Left & right, plus hole alignment
All, A happy ending. Clecoing in from the root to tip, I realized it was only the last 4 or 5 holes that were poorly aligned. I clamped the hockey stick in a vise (between two pieces of pine) and gave it a tweak, and the holes lined up well at #40 and cleaned up at #30. I clamped the hockey stick fl...
