Hi all,
I just completed my (first) tank and I'm moving on the upper wing skin(s). I have still not installed the tank because I'm waiting for the proseal to dry before testing the tank for leak, but I clecoed the top skins for a test.
Well, all the hole on skins and structure lines up perfectly, double checked the structure on the jig and it looks straigh... but I noticed a certain amount of oil canning on the 2 most outer bays.
I contacted Van's and Gus told me that is not uncommon... sometimes it looks better when riveted, sometimes changing the bend in the rib flange slightly make the skin tighter but that is only a cosmetic problem and I can leave it as is or, if I prefer, I can rivet or bond a few stiffeneres between the ribs.
Someone else experienced the same problem? How do you fix it?
Is possible that, even if everything looks square and straight, not installing the tank can cause this problem?
Thank you for your help.
