I work with a lot of rough sawn boards (Wood Mizer) that are up to 12 inches wide. The worse defect is twist. First I saw the stock to rough project lengths and then using winding sticks, I attack the twist with a #5 hand plane, gradually moving the winding sticks toward the center. If there is bow or cup I can plane that out also. I now have a reference surface that can go thru my planer. The finished boards are perfect. This is not really difficult or excessively time consuming.
Just a little nitpick on the tape measure blurb. The hook should not be completely tight. It should move in and out about a 1/16th or the thickness of the hook. This way you get an accurate measurement whether you hook a part to measure or bump up to it. If you want more accurate measurements with a tape measure, “burn” an inch instead of hooking or bumping the part. Just line up what you want to measure with the 1″ mark and subtract that inch from the final measurement.
