What is pocket joinery, how is it used, what are the best applications for it, and compared to other joining methods, what’s its strength.
Michael Dresdner: Pocket joinery means attaching wood by means of screws whose heads are hidden in diagonally drilled counter-bored “pockets.” It has all the same advantages and disadvantages of any screw joinery — it allows for more movement than rigid glue joinery, but may loosen in time and under certain stresses.”
Rob Johnstone: Pocket joinery uses cleverly created screw mortises to help accurately align a screwed together joint. The pocket joint also sinks the screw below the level of the wood. It is a great way to join face frames and cabinet wall together. There are many ways to do pocket joinery, but the easiest is with the help of a jig. The Kreg Jig is the best known of the off-the-shelf offerings.
