Follow the steps below:
Step 1: Use the flitch plate as a template to mark dowel locations.

Step 2: Drill 13mm holes perpendicular to the post at marked locations.

Step 3: Cut a 5mm wide slot on the side adjacent the drilled holes. Check that the flitch plate slides freely.

Step 4: Cut a 5mm wide slot on the side adjacent the drilled holes. Check that the flitch plate slides freely.

Step 5: Lower the post onto the flitch plate with the drilled holes aligned with the three holes in the flitch plate. Be careful to avoid rotating the post during installation.

Step 6: Drive the dowels into the post and through the flitch plate they should be roughly centred within the post.
