When I got home from work today I had a mission in my mind to get everything primed tonight. First thing was to mask off everything on the skins I didn't want primer on. This included the outside flange of where the access panels meet. Not totally necessary to do this, but while I have the priming system setup, why not? The hardest thing was masking off the access panels. Lots of tape to simulate the curve.


Before I started priming, I needed to set the pop rivets on the long pushrods. Since I had AKZO ready, I decided to wet set them.


after everything was primed, I had basically no primer left.....but enough to wet set the short aileron pushrods!


Skins and pushrods primed.


I drilled out the pushrods in the same drill press jig I used for the long pushrods. The plans specify AN470AD4-12 rivets, but they are just WAY too long. I tried one with a -12 and it fell over on itself. I thought I was screwed, but I was able to drill it out. To squeeze these rivets I clamped hand squeezers to the table. One hand for the pushrod, one hand for the pushrod. It worked very well. One issue to consider is you have a steel rod and aluminum rivets. The MIL-SPEC states you need to coat the hole and rivet with zinc chromate primer. So I used a toothpick to use the little AKZO I had left over to put into the hole and coat the pushrod. If you decide to do this too, make sure once the rivet is inserted fully into the hole to wipe off any primer from the end of the rivet - My first rivet slipped off the squeezer set because of the primer.


And the end product. Where I tried to do a -12 rivet the power coating is chipped, so I might give this another shot of paint.
