Cut the plugs from the blank
1 Mark a cut line
Note: Plugs cut using this dimension will protrude slightly from the
pocket hole, providing an extra margin for achieving the best fit. To
make shorter plugs, cut slightly farther from the end of the blank.
2 Apply a strip of masking tape across the plugs to keep them in
position while cutting.
3 Cut along the line at a 15° angle with a band saw, jig saw,
scroll saw, multi-purpose oscillating tool, or fine-tooth hand saw.
You also can cut the plugs square to the end of the plug blank and
then sand the end to a 15° angle.
ATTENTION
¾" [13mm to 19mm]-thick material, cut the plugs at the 15°
angle indicated. When plugging pocket holes drilled in material
thicker than ¾" [19mm], you can cut the plugs at 90°.
1 Apply glue in the pocket hole and/or to the plug.
2 Insert the plug, letting it protrude 1/16" [2mm] above the workpiece
surface.
3 Allow the glue to dry.
4 Sand the plug flush.
