4.Rout a 14"–38" wide slot 4"–5" long in the workpiece and 1"–2" from the short end of the featherboard, as illustrated in Figure 64.

5.Cut a miter bar that will fit in the table miter slot approximately 5" long (see Figure 65).

Tip: Consider making the miter bar longer for larger featherboards—approximately half the length of the total featherboard—to support the force applied to the featherboard during use.

6.Drill a 14" hole in the center of the bar, then countersink the bottom to fit a 14"-20 flat head screw.

7.Mark a 4" line through the center of the countersunk hole in the center, then use a jig saw with a narrow blade to cut it out.

8.Assemble the miter bar and featherboard with a 14"- 20 x flat head screw, flat washer, and a wing nut or a star knob (see Figure 66). Congratulations! Your featherboard is complete.

Note: The routed slot, countersunk hole, and the flat head screw are essential for the miter bar to clamp into the miter slot. When the wing nut is tightened, it will draw the flat head screw upward into the countersunk hole. This will spread the sides of the miter bar and force them into the walls of the miter slot, locking the featherboard in place.

Tip: The length of the flat head screw depends on the thickness of the featherboard—though 112" to 2" lengths usually work.
