We had around 20 mechanics at any given time in our shop. Working on tractor trailers, and doing alot of tires. We would have a a few hundred a week delivered. With 10 lugs per tire, we ate through impacts and had more out of service waiting to be rebuilt or returned than serviceable.

That is until one of us bought our own, which was an earthquake that was on sale. Instead of having 5 or 6 Ingersol or Chicago pneumatic on the floor being used, we all wound up sharing that one. It self destructed at some point, but it impressed all of us. The company made up keep the overpriced Ingersol's on the floor, but we had 4 or so earthquakes and solely used those for a few years.
