There's some useful info here, I don't know if you have dial indicators or not so this may not help you. I have all this stuff so taking the measurements isn't a big deal for me. If you don't have dial indicators then you can do it the old fashioned way with using grease as a visual indicator. I'll see if I can find something on that and post here too. Here's the link for a good how to.
