Meatball

Well it is the correct term. It’s also funny

My time has come.

I’m what the aerospace industry calls a “surface enhancement engineer.” A fancy way of calling me a peener. I mostly work with CNC air blast shot peening machines but the principle is essentially the same as a ball peen hammer.

Basically, hitting metal with hard ball causes little dimples to form on the surface of your work piece. Hit it a shit load of times and you get dimples all over. At the end of the day all those dimples help prevent stress fractures from forming.
