Tricks for truing lumber without a jointer

To flatten the board accurately,
cover your tablesaw with craft
paper and use it as a flat reference
surface when attaching the runners.

On roughsawn boards like this one,
the flattened area becomes visible
as it exits the planer. Make repeated
passes until the face is completely flat.

For a cupped board

Cut a pair of straight runners the length of the workpiece and glue them to both edges, as shown at right. After the glue dries, remove the clamps and run the assembly through the planer -- crowned face up. Continue planing until the planer flattens the entire top face of the board. Then, flip the workpiece over and run it through the planer again to flatten that face. Use your tablesaw to rip away the runners and square the edges.
