Brief Description: Wing spar counter-sinking continued #8
Slept in this Saturday morning, but I managed to get some more counter-sinking done. I finished the #6 nut plate screw hole and now I am on to counter-sinking the actual rivet holes (1 on each side of the screw hole) for each nut plate (AD-3). I had to drill the rivet holes out to #40 first and then started counter-sinking. Also I had to the pleasure of having Curt Jenkins over as a guest to see the project. Curt is the newletter editor for EAA Chapter 9. He interviewed Mitchel and I for an upcoming newletter article -too cool!!! Thanks Curt!
