Today was a two-part day. In the first session, I used a dremel tool to remove the weld on the vertical portion of the door threshold at the forward end. This was to allow for repositioning that piece so that it would attach properly to the aluminum piece that goes there. This also involved cutting loose the piece that I added on earlier.
I also addressed a small scratch that I made on one of the engine mount tubes. I sanded the area with fine sandpaper to remove the scratch, then sprayed a little bit of temporary primer to keep it from rusting.
In the second session I added on the front tubes for the skylight, cut the chordwise tubes loose, bent them to a slight curve, raised the front piece up, and cut out some new stringer tabs. This is all work that I wrote about a few entries back.
