Figure 6-18. Octagons are formed by making repeat passes on all four corners of square stock.
Octagons are formed by making bevel cuts on the four corners of a square piece of stock that has been sawn and jointed (Figure 6-18). Warning: If you work with the fence at an open angle, work with extreme caution. Use push blocks to move the stock. Make the cuts as diagrammed in Figure 6-19 to remove the corners of the square and form four new faces. When you must make more than one pass, don't change the depth of cut. Make the same number of passes on each corner.
