Brief workshop session after some yard work. Got the front elevator spar holes deburred (dang, there is a lot of them) and then setup a little dimple jig to save myself some hassle. Second photo there is the spar half dimpled (right side). Not the quickest work but those flush rivets sure do look nice when everything is put together. Sad part is that I have to do everything twice since the plane has two sides
