Dimpled the skins and the skeleton parts. Also countersunk the trailing edge wedge. I needed a jig to do this properly, so I made one using the trailing edge wedge from the practice kit. I had been saving this to practice rivetting the trailing edge on the practice kit before I rivetted the rudder trailing edge, but with the practice rivetting I've had I'm not concerned about this too much. I cut the practice wedge in two to make a spot where the countersink wouldn't hit. This worked great, the jig supports the wedge so that it is perfectly square to the countersink. I was able to countersink all the holes on both sides in 30 minutes or so.
