Kreg Jig K4 - Manual (Page 7)

There are several ways to join mitered pieces with your Kreg Jig ® . Depending on the
width of the boards, choose the method best for you.
For wider boards, simply place the mitered joint on the
jig, clamp it down and drill as normal.
For more narrow boards, you may need to raise the
heel of the miter off of the base to get your pockets in
the correct space.
For creating mitered corners with the Kreg Jig ® , we
generally recommend at least 3” wide boards. For smaller
stock, it may be helpful to place one Pocket-Hole on either
side of the joint, instead of two holes on one side.

Nominal Size vs. Actual Size
When you look at the labels on boards at the
home store or woodworking store, you may see
simple sizes like “1x6” or “2x4.” That’s the ‘nominal’
size of the board, which describes the board’s
dimensions before it was machined to fi nished size.
The fi nished size, known as the ‘actual’ size, will be
slightly less.
The markings on your Kreg Jig ® refer to the ‘actual’
size of your boards. If you buy a “1x4” at the
store, but measure it at home and it’s actually ¾”
thick, set your jig and depth collar to their ¾”
settings before drilling.
