Get the most from your planer
Group boards for stability.
Squeeze boards together on the infeed and outfeed sides when edge-planing. To plane the edge, a board must be square and true on all four sides, but slightly wider than finished width. If the workpieces are not exactly the same width, narrower boards (especially in the middle of three or more boards) can be kicked out by the planer. You can plane single boards or multiple boards at the same time, which helps them maintain a 90° angle, as shown.
