Inlet Ramps, etc ( 3 hrs )
Applied small RTV patches on firewall to prevent chafing from vertical hinge pin ends per Steps 1 & 2 at Sect 45-21. Then mounted Top Cowl to insure alignment at lower aft edge of Bottom Cowl. Used F14133-1 drill template for locating 6 holes to attach Bottom Cowl to Fuselage per Steps 3-7 at 45-21. Removed Top and Bottom Cowl, then re-assembled to prep for cutting out for Cowl Pin Covers. Coated Top Cowl with epoxy in new transition areas per Step 12 at 45-20. I'm revising Oil Door to use single "Cessna style flush latch". So I filled 2 large holes with AN426A-6-7 (spl ordered these large, soft rivets). First Mach C'sunk, then riveted, and ground/sanded smooth. Pleased with result! (see May 18 post with pic of test pieces and latch)
