Horizontal Dimpling
Hours this entry: 4.5Finally got the Horizontal parts primed and back to the hangar. It was time for a quick assembly to make sure everything still fits. I did have one issue with the primer on the end rib, as you can see there was a little bit that flaked off. I’m not sure if it didn’t cleaned well enough or what, but this is the only part I had an issue with.
Started to dimple the Horizontal skins, and figured I would show a picture of how I set up the platforms for the DRDT-2.

Tight Dimple Area
Hours this entry: 2.0Spent more time today deburring and dimpling the right side of the elevator to get it ready for primer.
The outer rib (HS706) is too compact to dimple the forward most hole with a squeezer, so you have to get a little creative. I’ve seen close quarters dimple die sets, which is basically just a bar with a countersink drilled in it, but we decided to do something different. We found that the full dimple would fit inside the rib w/o the squeezer, so we clamped a piece of scrap to the table and drilled a hole in it so the dimple set could be pushed through it. We then slide the rib over the dimple and tapped it with a hammer. Voila!
