Before you begin to make furniture, you need boards that are straight and square on all sides—in other words, four-square lumber. The jointer and the planer are an indispensable pair of tools for this job. In this course, power-tool expert Roland Johnson explains the principles of how each tool works and how to get the best results when using them. He discusses cutterhead technologies and possible upgrades, along with a foolproof technique to accurately set straight blades on these machines. Johnson demonstrates how to precisely align the infeed and outfeed tables to the cutterhead and how to accurately adjust the jointer fence to 90°, or to any other angle. He also shows how to identify the different types of warp that might be found in rough-sawn lumber and how to eliminate them using the jointer and planer.
