Cool stuff and congrats. I have had ours almost exactly 2 years now. It has turned an estimated 42,000 parts for us in that time. No real issues to speak of other than the vibrating closer. We did get it to vibrate very little though after messing with it several times. That really should be better on a lathe that cost what this one does. Half of the issue is the closer itself though, so not all Tormach.
Still if you can reduce it, then it won't effect anything.
