Figure 21-13. To square stock, start by squaring one corner on a jointer. Joint two adjacent sides so that they are exactly 90° apart.
The planer can also be used to square turning stock, furniture legs, and posts. Start by rough-cutting your stock square, leaving at least 1/8" extra stock for planing. Square one corner of the stock on a jointer, jointing two adjacent sides so that they are exactly 90° apart (Figure 21-13).
On the end grain of the stock, mark the sides opposite the joined sides S1 and S2. Set the depth of cut on the planer; then plane the stock with side S1 up. Without changing the depth of cut, make a second pass with side S2 (Figure 21-14). Continue in this manner until you have planed the stock to the desired dimensions. If you wish to square two or more boards, you can combine this procedure with the procedure for "Planing Boards to Identical Thicknesses," described earlier in this article.
