Ok, so now we arrive at "dimple-pallooza"... Full disclosure: I ordered some kung-fu special tool for this procedure. I know that aircraft manufacturers have been using dimples for decades, but recently, a tool has been improved.

Recently, aircraft tool supply came out with a dimple die that makes substructure dimples fit much better. I bought a set, and the results are amazing. The windup is that the skins receive a regular dimple, and anything connected to the skin, receives a slightly deeper dimple to make it fit perfect...

The net result is nothing less than perfection..
