Picking up from yesterday, II attached the top skin to the leading edge spar and bucked the rivets. They are AN426AD3-3 so they were pretty easy to buck. The bottom skin was easier then I thought it was. With the spar being over two inches wide, you have plenty of room to get a bucking bar in place without worrying about damage to the top skin. I used an angle iron mounted to my workbench to finish the trailing edge and came out very straight. The blind rivets that connect the balance tube installed really well. I followed the recommendation of the designer and tapped each rivet with a hammer to help the rivet lip match the contour of the leading edge.
