Hi John, I am curious as to why you want to cut the bottom out of the tank? If I had to make a decision there, I would cut the top off if I was going to cut one or the other off. Your plane is sitting upright most of the time I would presume, so it makes more sense to me if you are going to cover a top and sides inside the tank that it would be smarter to cover the bottom and sides to form a bowl to hold your fuel and then hope you get the top sealed back on properly. It would be better to loose some of your fuel out of a leaky top than all of your fuel out of a leaky bottom !! Maybe you have a simple leak around the drain tube or the fuel supply line coming out of the tank. I think I would investigate the fuel line coming out of the tank first, then start chopping the tank apart second. Larry H.

My engine and panel for N611GB are complete enough to start work on the 20 years of hangar rash and airframe issues. I have a few wing tank questions.. The notes that came with my plane indicate one wing tank leaks. I don't know what material was used to make them, epoxy, vinylester, etc. The tanks were abandonded by previous owners as the plumbing is missing. At least one threaded wing fuel cap is missing. I was thinking of cutting open the bottom of the wing and taking the tank bottom out. Then laying up 1 or two layers of light glass and vinyl ester resin inside the existing tank top and sides. At the same time replacing the filler necks, caps, vents, etc. Then laying up a vinylester flat sheet, again 2 layers of bid on something it can be removed from (suggestions? wax paper??) and later attaching the cured flat to the tank as a bottom plate (with flox?). Then foaming into place a bottom sheet of foam, sand to the shape of the wing then glass over and refinish the bottom of the wings. Can anyone point to a site outlining a re-work of wing tanks? Modern material on old glass?
