We seem to be completely failing to communicate here. I am suggesting that you use a gear (a in a physical bit of metal with lumps on it) that is rigidly connected to your spindle as the component that some gear tooth sensors sense. In the case of my own machine, this is the bevel gear that takes the drive from horizontal to vertical. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
