Winding Sticks

Winding sticks are not new; woodworkers have been making them for years from scrap wood and using them to check the flatness of material. Placed at opposite ends of a board, they accentuate any twist (wind), making it easier to identify and correct. With the sticks in place, sight across their top edges. If the edges are parallel, the board is not twisted. Reposition and repeat to check the entire board.
