|Started dimpling the top inboard skin
The inboard skin is really thick, much thicker than the outboard skin. I'm trying my best to dimple the holes with the C-Frame dimple shaft lined up with the legs on the work table. The dimples just seem to come out nicer.
|Re-dimpled the dimples
No matter how hard I try to get the C-Frame to put a nice flat dimple in this thick skin, each hole has an almost unnoticeable dip in the skin around the dimple. I went back over each dimple with my pop-rivet dimplers and got the "dip" out.
|Finished the inboard top skin.
I sanded the edges and put skin this away.
|Finished dimpling and sanding the doubler plate
I did the same routine on the doubler plate. It is thick just like the inboard skin. I did a single solid "whack" with the dead-blow hammer on the C-Frame dimpler and then went back over all the holes with the pop-rivet dimplers to get the craters around the dimples out. I know this routine seems a little extreme with double dimpling the holes, but when I did this on the left wing, the skin looks absolutely perfect when it is riveted on.
