router mortise jig

I've made this relatively simple new jig for routing mortises using the plunge router and guide bushings. The first step is to cut a piece from the middle of a board equal in size to the selected guide bushing.

Then the base must be glued with an opening to allow for the guide bushing to move a distance equal to the length of the planned mortise, plus an allowance for the different sizse of the router bit and guide bushing.

A guide is added to the underside to position the jig in the right place so that the cut will be centered in the stock. In my jig, I used spacers to adjust the position so I can use the same jig for different thicknesses of wood. The jig can either be clamped in a vise or can be clamped directly to the stock.

Make, fix and create.
