Horizontal Stabilizer Ribs Dimpling (Part 2) - Final

We finished dimpling the horizontal stabilizer ribs, after getting the replacement parts from the airplane factory, additionally, we had to make some tool changes such as grinding the dimple die edge a little, in order to get consistent dimples.

Tools

In order to get consistent dimples, especially in hard to reach places, the female part of the dimple die was sanded a little from one side using a grinding wheel. Additionally, with the impact dimpler, it helps to listen for a distinct sound of metal impacting, which means the die completely formed the dimple, and no further impact should be needed.
