This is basically the same as the arc jig in the first segment but for a straight line rebate in a spot where it would be a bit of a shame to miss the target.
It starts out as a piece of 1/4” MDF glued to a piece of 1/8” plywood. The plywood is more than 1/2 the width of the router base. Use the bit you plan to use for the cut and trim the plywood using the MDF as a guide.
Now when you set up to make the cut you can see exactly where it will fall on the workpiece. No measurements need to be taken.
When I use measurements I find that there is always a way to screw them up so I avoid them with little jigs like this whenever I can. In this case I’m installing a 3/16” wide banding between a marquetry surface and a solid one. I’m using a 1/8” bit and after the first cut I will fit the one edge of the banding against the first cut and the jig tight against the other. The second pass will make a perfect fit and again I won’t have to measure anything.
I usually make these sort of jigs for a single job and chuck them when it’s done. If you keep it mark it with the router and bit size it was made with.
This jig is just common sense and probably not news to most of you but I just liked how easy it made a “high pucker factor” rebate slide by with no real sweat on my side of the router.
Thanks for looking in.
