Help / advice needed for routing a tapered groove


I would like to learn a technique for consistantly routing a tapered groove in a 3/4" piece of wood. It needs to start (or end) at zero and taper within a length of 2" to 3/4 in depth (basically ending with a hole) The groove will be 1/2" wide. Thanks!

Get 2 sticks. Taper them down from 3/4 to 0 at the lenght you want. Glue them to a bit of MDF/PLY. Cut a slot in the board to accomodate a router bit and guide bushing. Or cut 2 more sticks and glue them to the other side as a router guide (parallel and as wide as the router base - like railroad tracks that the router will slide back and forth between). You now have a jig. Clamp the board to the work piece and route the taper.

You're prolly right.
If so, use Kentucky Windage to add some to the angled sticks but watch out that the router bit does not end up extended an unsafe distance.
Now that the first reply has given you the basic shapes, sketch the problem on a sheet of paper.

If I understand correctly this groove is "tapered" from to to bottom. If so, you could make an angled block or ramp for a router to ride on. If necessary for your application you could make a base for the router with a matching slope, that would ride on the ramp attached to the work piece. This would keep the router perpendicular to the workpiece, so that the sidewall at the end of the groove was perpendicular to the face of the workpiece also.

If I didn't have a lot of these to cut, I'd consider a pair of 1x ramps, a chisel, and a router plane.

We know you Morris, you'd just program G01 X2. Z-.75.
