Brief Description: Right Elevator - Blind Riveting Ribs
Having completed the left elevator with so little difficulty, I was pretty comfortable about doing the task again. I did the first 28 blind rivets with no difficulties. Then had a short distraction and came back to do the final four. Of those 4, I managed to set 2 badly. The LP4-3 normally sets with two distinct lumps on the manufacured end. In this case, I managed to get one lump on either side. The rivets were the furthest in which are impossible for me to look at while squeezing. Being the furthest in, they are also the hardest to drill out.
The approach I took was:
I made a small dowl with a smoth end and a hole slightly larger than the rivet tail, but much deeper. I took a #51 drill and ran it through a second piece of dowl at right angles which allowed me to lower it down and insert it into the shop head of the rivet. I held the smaller dowl with the hole on the back of the rivet while my wife kathleen carefully hit the #51 drill with a long handle small headed hammer. It worked perfectly, driving out the shank of the rivet without causing any damage to the rib. I then used my sioux right angle drill to drill out the manufactured head (which was smaller than the shop head side due to the original imperfeection). I was amazed that they came out without any damage to the ribs. I replaced the LP4-3s taking a lot more care this time....
