Quick and easy board straightener
I don't spend extra money to have a straight edge milled on the stock I buy because a long time ago I figured out a way to straighten virtually any board on my tablesaw as long as it's fairly flat. All you need is a straight scrap of material you can screw to the workpiece, as shown. The straight scrap rides against the fence allowing a straight cut on the opposite edge. With one straight edge in place, you only need to remove the straight scrap, turn the board around, and straighten the other edge. The attached trowels help me hoist large workpieces up to tabletop height.
