I would like to reiterate, square rule doesn't always need chalk lines, some times but mostly not. It seems, through this whole thread, lines are attached to square rule, lines are an exception. Tim
I understood everything except this comment by Tim. If you aren't using a chalkline, Are you then using the reference face and therefore reverting to mill rule? Please explain further so I can understand what you mean. How are you doing square rule if not using chalk lines?
