Dennis sent this pic to me yesterday morning.
We all come to rebuilding with different experience, perspective and goals.
While not required, he is hoping that you might think about this excerpt (from something). Perhaps look up terms and think about flatness, and how it is measured and what it does. Especially in reference to other features.
If you have a copy of Foundations of Mechanical Accuracy by Moore, and/or Connelly's Machine Tool Rebuilding you choose to peruse those in prep for the week.
Moreover think about your short and long term life goals relative to rebuilding. The more questions you bring to this party the more powerful it will be. And we will consequently all learn from the dialogue.
