Step 1: Prepare the Outriggers

Screw the two scrap outriggers -- 3/4" x 3/4" pieces of wood, each 4" longer than the board to be planed -- to the sides of the board to be planed. Make sure to countersink the holes so the screws won't get caught inside the planer.

Step 2: Plane the Boards

Send the board and its outriggers through the machine as you would a large piece of wood. Remember that the planer automatically sends the wood to its outfeed table, so there's no need to push the wood through.

Step 3: Remove the Outriggers

Use a screwdriver to remove the outriggers.

Use a jointer or hand-held planer to smooth the rough edges where the outriggers were attached.
