That was a lot of work to move the antenna. I drilled out all of the previous doubler rivets and removed the double let and the fill plate. I wasn't in love with the previous doubler plate so scrapped it and made another with 0.060” plate I had specific for making doublers. I was able to salvage the fill plate and use it to transfer the hole pattern to the new doubler and the bottom skin. Took some careful back and forth, but go all the hole redrilled. Made a new splice plate to patch the old antenna hole in the bottom of the skin and then made a small circular plug to fill the hole. I put three small oops rivet to hold the plug. Got everything deburred, countersunk and then Alodined. Alodine came out good. Will need the dimple the bottom skin with close quarters die and then rivet. Good for now though. 1/6: Dad was in town, and we were able to get the cover plate and new doubler riveted into place. They're alodined, but I will paint them before I close it up.
