3/29/19 2.2 Hours Marked spots on inside firewall for bolt holes. Pilot drilled then up drilled for AN3 bolts 4" apart. Removed oil tank for access to holes. Deburred. Made a joining piece from L angle and added a piece of grommet edging to protect coax. Installed bolts with flat washers both sides of firewall, 1" spacers, L angle, padded clamps, normal washesr and nuts. Good, solid harness support. Reinstalled oil tank.
3/30/19 2.7 Hours Clecoed one eared nut plates into place for comm head with a washer sandwitched between the instrument panel and instrument bulkhead. This gives a space between them so when back drilling through the nut plate into the bulkhead I don't drill into the panel. Finished the four nut plates for the radio head. Tried the head for fit. Had to file a little off nut plate edges that were encroaching into the radio head hole. Tight fit. Tightened throttle in panel and put throttle support into place on backside of bulkhead. Marked holes and back drilled bulkhead. Back drilled hole in panel for right side backup throttle rod.
