Brief Description:  The strake cleanup and right wing woes

The left wing was removed after properly contouring the micro down just under flush with the wing. I spent another 2 hours finessing the micro borders and getting a real nice even gap line sanded down. Next step will be to add a ply of glass on the inside of the flox bead to strengthen the lip edges.
After hanging up the left wing I installed the right wing and encountered two big problems. First being that the aluminum C-Channel was distorted by the bolt heads far before proper torque was applied. I spent a good hour removed the C-Channel and making a new one that was braced by 2 L brackets rivetted in place. This however did NOT solve the problem so I performed a small test. I used a torque wrench and set it to 150 In lbs and still could not reach torque without distorting the channel. Now I don't know how Redmon and the other guys are doing this but I'm assuming it's a much more stout C-Channel. I'm tempted at this point to make one out of steal but I'll have to come back to this issue later.
Next I noticed that my wing/strake intersection was WAY off. Either the wing was built bad, the strakes were built bad or all my efforts to set the correct incidence were not done correctly. I didn't build the wings and have a chance to setup the board so I'm being creative in finding the correct setting. Finally, I decided to go ahead and set the washers for both wings to be identical and when I did the wing and strake was almost PERFECT. I've decided that I will fly the airplane with this setting and deal with changes of incidence after that. who knows, I may have it perfect.
