Performed the stitching between the F891R and F823R with F804H. On either side of the spar opening, I riveted the AN470-4 rivets along both sides with the exeption of the two closed to the bottom of the aircraft. The plans call for MS42 POP rivets, I Counter sund and installed AN426-4 so the clearance of the spar is maintatined. The process went well. I set four rivets along the side then unclecoed the pannels and tipped the pannels out so I had clear access to the seam. While doing so I found four holes by the F806 rear spar that I had not dimppled. So I remove the skins and dimpled the skins, the frame is another problem. I could dimple the two forward of F806 but the area behind F806 is to tight and I will need to come up with a solution.
