Short Description: Finish Antenna Doublers
|
Set up the countersink for 0.007 deeper than flush. Counter sunk the comm and transponder doublers for dimples. The ADSB doubler will be dimpled. Deburred all the doubler mounting holes in the fuselage. Set up the alumiprep and alodine process at home. Put the table near the garage door with a fan at my back. Made up four trays with alumiprep per instructions for dipping at 3:1 ratio, water rinse, alodine at 2:1, and water rinse. Put a piece of hardware cloth across sawhorses for a drying rack. Wore protective gear. Put the doublers in one at a time for 3 minuts in prep, rinse in water, 3 minutes in alodine, rinse and set parts out to dry. Closed containers and will use these solutions to prep inside of fuselage.
