To flatten the face of a twisted board, first decide that are the excessive corners. Begin there and aircraft progressively bigger sections till the face is flat.
Assess the twist with winding sticks. By sighting down the board with winding sticks, Van Dyke checks how a lot the board is twisted, and what number of sections he’ll should divide it into for planing.
Take the time to attract the grid. As a result of the sections for twist are extra complicated than these for bow or cup, Van Dyke attracts them on the board. Roughly divide the board in half in its width and size after which subdivide every half into equal sections.
Aircraft from excessive corners inward. After wedging and clamping the board, take overlapping cross-grain shavings to flatten the opposing excessive corners. Often test your progress with winding sticks. If it’s worthwhile to do subsequent units of shavings, you’ll in all probability divide the board into fewer sections to keep away from taking off an excessive amount of materials.
