Did final fitting of weight to skin. Deburred and Dimpled all skin and countersunk the fiberglass caps to match. The microstop tool did not fit flush on the caps because of the lip so I put some electrical tape around the lands of the countersink bit for protection and insurted it into the air drill , worked fine. I tried to get a tight a fit as possible as I heard alot of cases of filler cracking after a while, probaly due to the expansion and contraction of different materials. Blind riveted cap The left elevator is complete.
