There was a time when Gary Rogowski was convinced that his jointer was possessed. Since then, he’s discovered that edge-jointing problems, though common, are almost always correctable. He says the most overlooked detail when edge-jointing lumber is what the board looks like to start with. He explains how to get a flat reference face, how to read the grain to prevent tearout, how to check for high and low spots, and techniques for both hand-jointing and machine jointing. Boards planed at complementary angles mate flat, he says, and the jointer must be well-tuned to create straight edges. Rogowski diagnoses jointer outfeed-table problems, shows how to joint a long board, and discusses how to handle problem boards. Then he talks about trying not to get a straight edge – when he makes a spring joint.
