Brief Description: Finish plate nuts on left wing and start right win
1. Spent 1 hour just getting the single platenut on the left spar installed. It needs to be rivited inplace before it is countersunk. I could not get to the rivit nearest the rib with anything I have to buck it. Finally decided to poprivit it. Drilled it out to #30 first and counter sunk it a bit before setting the pop rivit. The other rivit was more accessable and was bucked. I then used a #40 countersink to countersink for the #8 screw hole. I made a dimple in a scrap piece of aluminum first to use as a gauge and then countersunk the hole. You use a #40 so that it will guide into the plate nut hole., It works ok however. I had a similar issue on the skin by the spar. I used a lug platenut for the rivit but still could not get a dimple die in place because of the spar. The skin is realy too thin to machine counter sink too! I elected to install the nut first and machine counter sink carefully. Its not perfect but will work. See pic #2 below. Besides, its covered by the fairing when installed. 2. Put the 3 access panels back on the bottom of the left wing 3. Removed the access plate for the stall warner and then installed a missing rivit on the access panel flange. 4. cleaned all the blue sharpie markings off the bottom of wing
5. Moved to the Right wing to do the same exercise of installing 33 more plate nuts. With my trusty platenut jig, I drilled all rivit holes for the plate nuts (66 rivits) and then debured each on both top and bottom
6. Cleaned up the work area for next time.
The last plate nut on left wing. Used a pull rivit closest to rib due to lack of room for bucking bar
Used a lug type nut here so that a rivit isnt on the spar-plans dont say to do this
