I deburred, dimpled, and edge prepped the J-Channels today. I then drilled the longeron attach holes in the top skins to full size. I didn't do this while the skins were clecoed to the fuselage because I didn't want to mess up the already prepped and dimpled holes in the lower skins and longerons. Once these holes were drilled I broke out the soldering iron and started removing the plastic along the rivet lines. Stevie helped me with this.
