5. Cut a miter bar approximately 5" long that will
fit in table miter slot, as shown in
Figure 76.
7. Mark a 4" line through center of countersunk
hole in center, then use a jig saw with a nar-
row blade to cut it out.
8. Assemble miter bar and featherboard with
a
1

"-20 x flat head screw, flat washer, and
a wing nut or a star knob (see
Figure 77).
Congratulations! Your featherboard is com-
plete.

Figure 77. Assembling miter slot featherboard
components.
Note: The routed slot, countersink hole, and
flat head screw are essential for miter bar to
clamp into miter slot. When wing nut is tight-
ened, it will draw flat head screw upward into
countersunk hole. This will spread sides of
miter bar and force them into walls of miter
slot, locking featherboard in place.
Tip: The length of the flat head screw depends
on thickness of featherboard—though 1

⁄
2
" to
2" lengths usually work.
Now, proceed to Mounting Featherboard in
Miter Slot on Page 51.
6. Drill a
1
⁄
4
" hole in center of bar, then counter-
sink bottom to fit a
1
⁄
4
"-20 flat head screw.
Tip: Consider making miter bar longer for
larger featherboards—approximately half the
length of total featherboard—to support force
applied to the featherboard during use.
