Got the leading edge skin riveted to the spar assembly and installed the blind rivets to the counterweight. Installed the top skin and cleco'd in place. Had a few that didn't set tight and I was able to drill out and redo. Learned I need to lean the gun slightly toward the edge to keep it tight. Riveted the end ribs to the spars and then cleco'd the bottom skin in place just to see how it all looked. 8/18: got the bottom skin riveted with no problem. Had to make a little spacer to rivet the three end rivets that sit below the level of the skin. Of course, I mounted it temporarily to the wing just to see how it looks. Decided to try the tape method. The wedge sticks out slightly past the skin and I was worried about how to align the tape on the wedge so it didn't stick out. Turns out the width of tape is perfect when aligned with the top of the wedge. Got the parts cleaned and applied the tape to both side. Let it sit 20 minutes for an initial cure then cleco'd through the tape every 10th rivet to make sure it was all aligned. Then unclecod the bottom skin and removed the backing from the bottom of the wedge. Pressed it down and cleco'd as I went. Let that sit a little while, then came back and removed the clecos to expose the top of the wedge. Then removed the final backing and squeezed it tight while clecoing every hole. Looks good. I'll let it sit for about three days to cure before riveting.
