So I tried to follow Van?s instructions on fitting the fuel tanks and ran into some issues with alignment on the Z brackets. I guess I need to figure out how to drill an ?exact? hole Now I am trying a different method.
I manufactured a small plate with the same hole locations as the outboard aft corner of the fuel tank skin by back drilling the fuel tank skin. I bolted the Z brackets to the spar, clecoed the plate to the baffle and screwed the plate to the spar. You can see this in the picture. Things seem to align pretty well.
I will now use the baffle to back drill the 1/8? holes into the brackets. I hope this works better than relying on my measuring and drilling skills
