Today, I began the actual installation of the wingtip stiffener dowels in the lower half of the left wingtip. First, I tacked the dowels in place using medium CA glue and Zip-Kicker. after a few minutes to let them set a bit, I mixed up some micro mixture in a small plastic cup and applied it along the sides of the dowels, using a wooden ice cream spoon to create a nice fillet on each side. In a few days, I will apply 3" fiberglass tape over the dowels.
I also finished making the coax connector mount for the marker beacon antenna, tacked it in place, and applied two layers of fiberglass tape over its mounting tab to hold it in place.
