I made this kerf making jig a few years ago but I don’t think I ever shared it here. It helps you to create tight fitting half lap joints very easily.
The screw can be tightened or loosened to create tighter or looser fitting dadoes. The width of the wood and screw minus the width of the wood equals the width of your saw blade.
How it’s used:
1. Cut one is made with the work against the end w/o the screw w/ the piece to be inserted between your miter gauge stop block (see picture 3).
2. Second cut is made by flipping the jig over and removing the inserted piece and referencing the work off of the screw end.
3. Clean out the material in between the two cuts.
(width of wood and screw – width of wood) = width of blade kerf
