Lots and lots of scuffing in preperation for priming. Got all metal for both the horizontal stabilizer and Elevator scuffed, cleaned with soapy water, and dried. At the end of the day my short screw in drill bits arrived and I was able to install the cable attachment for the Yaw trim wire on the front of the rudder. Drilled the #10 hole, scuffed for burrs, and used my fabricated nut holder to install the nylon nut and screw. Not the easiest thing in the world, but it worked and I didn't have to drill out the leading edge rivets to gain access.
