Enlarged fuselage scoop holes to 15/64" to accept the 10-32 Rivnuts
Cleaned the area around the holes with acetone for better bonding of the Loctite
Installed 33 rivnuts NAS1329A08K75 using a small amount of Loctite 262 Threadlocker on the outside of each rivnut.
- Had a problem with the install tool on the 32nd rivet when the tool threaded shaft came loose from the bolt used to tighten/compress the rivnut, leaving the shaft stuck in the rivnut just set. Finally backed the shaft out using vice-grip pliers, and upon inspection found that there is a set screw in the bolt that holds the shaft and had come loose. Reinstalled the shaft into the bolt, tightened the set screw, and installed the final rivnut.
