One of the items on the to-do list is to get the countersinks completed, and install the screw and nut for the F-796 tank attach angle.
I opted to follow the drawings an countersink, although I see some on the build logs choose to dimple this hole. I made my first countersink shallow, and worked up to the proper depth little by little. The area is so tight and snug to fit the nut. Fortunately I have a 3/8" socket that I have ground down for such tight spaces and it has done the trick of tightening the nut.
