First mistake

Today I received my DRDT-2 Dimpler. This thing is pretty bad ass. For those who don’t know, the sole purpose of this machine is to place little dimples in the aluminum so the rivets will sit flush. It does seem there is a divide in who likes it and who doesn’t. Personally I have ZERO desire to whack a hammer 3,283,394 times to get the perfect dimple. It’s getting covered in paint and I doubt there is enough of difference to justify it. The number one downside is its pretty easy to get on a roll while dimpling, more on that later.


After I got the table built, I began to start dimpling away at the Vertical Stabilizer skin. As fate would have it, With only 6 holes left to dimple, I dimple  a hole that should not be dimpled. While this on its own right was not the end of the world. I made it worse. I knew I wanted to use my steel back rivet plate so I had a hard smooth surface. But in a stroke of genius, I decided to use a bucking bar on top of the dimple with my rivet gun. This put a slight crease in the skin about 2″ long. I’m still on the fence if I should replace this.


I also picked up some SEM EZ Coat primer for long term protection. I had to order some Acid Etch and that will be in on Tuesday. But I gave a test run of 2 coats on some scrap and it looks pretty good. I’m not sure if I’m sold on the color yet though.
