If you can ask some more specific details, I can probably get you a good answer. I am not the mechanical guru, but can pass this along to him. Additionally, I have access to some good procedures. If you'd prefer, email me directly for a more detailed answer at [email protected]

In order to keep your uncertainty somewhere in a working range, you will need a specialized comparator (gage block comparator), or a helium-neon laser. Neither are cheap.

If you are in the USA, the standards that apply are ANSI/ASME B89.1.2M and ANSI/ASME B89.1.9M. The older standard is GGG-G-15C, which is available for FREE at ASSIST online http://astimage.daps.dla.mil/quicksearch/ . Type "15" in the Document Number field, then scroll to the document.

Hope that helps a little!
