With all of the skin holes match drilled to the skeleton and the vinyl removed from the rivet lines, it was time to dimple all of the skins. I attached a small shelf between my two work tables, which allowed me to set my DRDT dimpler at just the right height between them. I dimpled all of the holes in the upper and lower skins, and deburred all of the edges. I also cut the two wing walk doublers, and back drilled them using the top inboard skin as a template. Vinyl was then removed from the doubler plates, edges were deburred, and holes were dimpled. I then test fit the leading edge and the fuel tank on each spar. Moving closer to riveting the skins to the skeleton!
