Flattening an extremely warped board on the jointer
In this video, Bob Van Dyke shows you how he flattens a board that many would consider too warped to use
Flattening boards on the jointer is usually a straightforward process, but sometimes extremely warped or twisted boards can present a challenge. According to Bob Van Dyke, the problem comes when the normal process for flattening–which involves changing where you’re placing pressure on a board as it moves over the cutter head–leads to a cut that follows the twist instead of removing it. Bob’s solution is to place a single patten in the center of the board and use it to pass the entire board over the cutter head without ever changing where he applies pressure. He’s also sure to split the difference in the warp, balancing the board off of two corners at the beginning instead of three, to ensure he doesn’t end up with one very thin corner by the end of the flattening process.
