Tonight I set the last two rivets in the right flap; one on the top and one on the bottom at the trailing edge of the inboard rib. As with the same rivets on the left flap, I used the indirect method as shown in a December 19, 2008 EAA Hints for Homebuilders video (http://eaavideo.org/video.aspx?v=5337092001 ). The bottom one set fine, but the bar slipped on the top one (of course it happenen on the TOP :O( ) and I mis-set the shop head. I drilled that one out ok, but the next one clinched, so I drilled that one out and just set an MK-319-BS.
