  1. Paul suggested that the combo of pencil and mortise gauge instead of a marking gauge to set the boundaries of the mortise hole was good enough because he had taken the time to mill the wood as precisely as possible. What are the acceptable tolerances in thickness and width when “milling as precisely as possible”? When working on my own projects, I will try to get my matching dimensions to within a few thousandths of an inch. For example, the thickness along the two edges of a board I was hoping to plane to 1.25 inches might vary from 1.247 to 1.256 inches. Should I be shooting for greater accuracy?
