I've been cranking away on this project. Mostly just trying to get the ATC dead reliable, but I have also machined some parts. I had to machine some flats for a wrench on a shock perch (actually a short run of perches), I modeled them at .7355" and they all came out damn near spot on. Even with the micrometer it was only about +/- .0002". I was really impressed because when checking things out I've realized that my X axis jibs are a spot loose. So I can't complain.

All of that said, the ATC is really getting there. I went through several hundred tool changes today. It's gettin very consistent, but the little hiccups are still filtering in. This is a really good thing. In endurance racing you realize you have to work things until the unexpected happens. I have found a few of those items in these test runs. As they get worked out, the tests runs will get longer, the errors fewer, and eventually the test runs will turn into manufacturing runs. I'm very close.
