5. Cut a miter bar that will fit in the table miter
slot approximately 5" long, as shown in
figure 107.
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.

countersink the bottom to fit a 1 ⁄

tersunk hole in the center, then use a jig saw

with a 1 ⁄

and a wing nut or a star knob (see figure
