Laied out top fuel tank skin and drilled the spar section 32mm, I think it should have been 64mm but it was too late by the time I relized it so 32mm will have to do. After that, I removed the skin and positioned the fuel tank and marked some lines where it should go. Removed the tank and placed it on a make shift table, placed the skin on top and mached up the lines. Then I marked perimiter lines around the tank on the skin, flipped the skin over and drew more lines 10mm inside the perimeter lines and marked location of holes 32mm apart. Drilled the holes in the skin and flipped it back over and placed it on the tank, lined it up and drilled the tank, it fits perfict. Located fuel line ports, marked and drilled. It was a productive day.
