This weekend I worked on the right main 198 Liter wing tank. A lot of prep work went into it. Last week I sealed the internal fuel tank structure and this weekend I installed and sealed the internal structure to the tank skin. Even with everything test fit, reamed, scuffed up, cleaned, test fir etc. I used almost every minute of the two hour working time of the B2 sealant. This includes a lot of help from my wife, I literally could not have done it without her. I let the tank cure one day while clecoed to the wing spar. Inspecting everything afterwords it looks great and I am very happy with how everything came out. I still need to seal and rivet the two end ribs and am going to add a little extra sealant in some of the corners and also encapsulate the backs of all the rivets for insurance. The tanks are taking a lot more time than I thought. But, I am hopeful that I wont have to be chasing down leaks later.
