      2. Lay out and drill pocket holes

       following the manufacturer’s

       instructions on the non-show

       face. Place at least two screws per

       joint if possible.

      3. Apply clamping pressure

       to the assembled joint so the

       boards don’t shift. Glue is

       optional, but doesn’t hurt.

      TIP

      Avoid screwing into end

       grain. The pockets are

      usually drilled in such a way that the

       screw itself is biting into edge or

       face grain when the joint is pulled

       together. Screws are weak when

       driven into end grain.

      4. Pocket screw companies

       make handy clamps that help

       keep the joint nice and flush.

       These can be used in addition

       to the regular clamp.

      5. Drive the screws into place.

       The screw helps close up the

       joint.

      6. This joint is easy to make

       and surprisingly strong.

      FRAME BUTT JOINT USING DOWELS

      Another option for connecting frame parts is dowel joinery. Holes are drilled on

       both workpieces and premade dowels are inserted with glue. Dowels have the

       additional benefit of being completely hidden.

      1. Arrange the parts to be

       joined and mark the dowel

       locations across the joint.

      2. There are many dowel jigs

       on the market, but self-centering

       dowel jigs are the most useful.

      3. Align the desired hole size

       with the lines on one of the

       workpieces and secure the jig.

      4. Drill in the hole using the

       desired drill size with blue tape

       wrapped around the bit serving as

       a depth stop.

      5. Move the jig to the remaining

       holes and repeat the drilling

       process.

      6. Repeat the drilling process on

       the adjoining workpiece.

      7. Insert dowels into each hole.

       For a more permanent

       connection, add glue and

       clamping pressure.

      TIP

      You can make your own

       dowels using a simple device

      known as a dowel plate (a thick piece

       of steel with various common sized

       holes in it). Scrap wood can be cut

       or riven slightly oversized and then

       pounded through a dowel plate

       to create dowels of the

       desired diameter.

      ALTERNATIVE METHODS

      HOMEMADE DOWEL JIG ALTERNATIVE

      A dowel jig is a nice convenience and offers increased accuracy and repeatability, but it is certainly

       possible to save a few bucks and make a shop-made doweling jig out of scrap wood.

      1. Lay out the desired hole

       locations on a thick piece of

       scrap. Keep in mind, because

       this jig is made of wood, the

       holes will eventually wear out.

       Consider it disposable.

      2. Drill the holes as straight

       and true as possible. Keep a

       large square nearby to give a

       visual reference.

      3. Glue another piece of

       scrap to the reference side of

       the block to serve as a stop.

      4. To use the jig, simply clamp

       it to the board, lining up the

       reference marks with the drill

       locations on the workpiece, and

       drill away.

      5. After drilling the dowels in

       the adjoining piece, glue and

       assemble as per usual.

      FRAME BUTT JOINT USING DOUBLE BISCUIT

      Biscuits can make quick work of frame assembly, but for some applications, a single

       biscuit just doesn’t seem strong enough. So let’s add two biscuits
