This corner jig is so easy to make and so easy and accurate to use, you
will be kicking yourself for not thinking of doing this
1/2" plywood; 24" x 24" square
(any dimension of your choice)
2 x 4 x 4'
1 1/2" wood screws
Step 1 - Select 1/2"
plywood and cut it into a 24" x 24" square or
dimension of your choice; use a
carpenter's square to confirm it is square.
Step 2 - Select the 2 x 4 and
cut one piece to 24"; cut a second piece to 21 1/2"; ensure
all edges are cut to a perfect 90 degree angle; best to use
a chop saw or a miter box to ensure accurate cuts; use a
carpenter's square to confirm squareness.
Step 3 - Working on a flat
surface, select the 24" x 2 x 4 and clamp it to one side of
the 1/2" plywood square; use the 1 1/2" screws (three or
four screws) and input the screws through the plywood into
the 2 x 4; ensure that the edges are flush/even; this 2 x 4
will be considered the base/bottom of the jig.
Step 4 - Select the 21 1/2" 2 x
4 and place it perpendicular to the base along the left edge
of the plywood and clamp it in place; using a carpenter's
square, ensure the junction of the 2 x 4's is a perfect 90
degree corner. Screw this 2 x 4 into place.
Your corner jig is now complete and
ready for action; you can now repair broken drawer panels;
assemble box corners and picture frames with ease.
