Steps to Building a Miter joint
1. Plane material to uniform thickness, rip to width and rout rabbet if desired.
2. Cut desired miter on workpiece and position to drill pocket holes.
There are a few different ways to join mitered pieces with pocket hole
joinery. This example below focuses on joining two 45 degree mitered
pieces by placing two pocket holes across the workpiece perpendicular
to the edge of the miter as shown in the image at right. The workpieces
are 3" wide with a 3/8" rabbet along the inside edge.
a. Position one workpiece so that the edge
of the miter rests entirely on the base of
the jig and the drill guides will not interfere
with the edge of the board or the rabbet as
shown at right. On this 3" wide piece, use
the A-C setting of the Kreg Jig
1-1/2" center to center pocket hole spacing.
b. If your workpiece is less than 2" in
width, you may need to raise the heel of
the miter off of the base of the jig slightly in
order to get the entire impression of the
pocket hole on the backside of the
workpiece. Adjust drilling depth and screw
length accordingly in this situation.
3. Clamp and drive screws.
You can use many different styles of clamps
to hold the workpieces flush while the
screws are driven. If you will be assembling
a number of miter joints you may want to
produce an assembly fixture to help hold the
toes of the miters in perfect alignment. The
fixture consists of a piece of plywood that
has two hardwood pieces attached to it to
form a perfect 90 degree angle. You can add
an overhead clamp to this fixture to produce
consistent clamping results.
