Image 1) Fastened entire rear channel first with silver clecoes. Left the Aileron holes at 3/32 and opened up the rest to 1/8. Worked the ribs next from center out with silver clecoes working forward one line at a time untill I ran out of the sliver. I began replacing them with copper and kept working forward from the center out.
Image 2) Removed ann the clecoes to un clamp the skeleton from the bench. Then re clecoed every 3rd hole.
Image 3) Used dimple dies to counter sink the tack rivets.
