Router Edge Guide
Can You Build Your Own?

Sure, you can build your Router Edge Guide! The question is how?

Here is an easy answer. Build two edge guides for your router. You will be amazed at how you can use them.

First, build your edge guides to fit your router. I made my first ones to fit the Mortise Jig and the Dewalt 621 Plunge Router. They are easy to make and add versatility to your shop.

You can adapt one to do circle cutting. How would you like to cut a circle to nearly any diameter?

You use both edge guides to make fingers for Featherboards. The two edge guides give precise alignment.

Two edge guides allow you to trim a cavity for a precise fit.

In fact, you can use them for so many things. You can dado any board to any length and depth that you like. You can make dadoes for shelving.

With custom edge guides, your imagination brings many uses to mind!

How to Make A Router Edge Guide:

Woodworking Routers

Materials List: Hardwood (Oak, Maple, your choice) [All dimension for Dewalt 621]

  • (2) 3/4" x 5 1/8" x 1 1/2" (backs)
  • (1) 1/2" x 5 1/8" x 3 1/8" (base)
  • (1) 1/2" x 5 1/8" x 1 7/16" (base)
  • (2) 5/16" dia. X 18" Stainless Steel Rods
  • (4) Threaded Inserts & Hex Socket Set Screws with Brass Tips


  1. Prior to cutting the backs and bases, rabbet the 3/4" backs at bottom on outside edge. Rabbet is 3/8" wide (one half thickness) x 1/4" deep.
  2. Make dado 3/8" wide x 1/4" deep in 1/2" thick base material and 3/8" from back edge. Dado needs to fit tongue on 3/4" backs.
  3. Cut the backs and bases to about 5 1/16" long. Use a stop block on your table saw fence so all are the same.
  4. Drill two holes 5/16" diameter through the 3/4" Back at 1/2" from bottom (depends on Router). Center the holes 3 5/16" apart (depends on router).
  5. Drill a 3/8" hole directly above the rod holes for threaded inserts.
  6. Drill a 1/4" hole in the center of the backs 3/8" up from the base top. Tap the hole for 5/16-24 thread. This is to control side movement.
  7. Glue 3/4" Backs into 1/2" Bases.

The Steps in Video Format:

For circle cutting, make a simple edge guide with the backs only, but 1 1/4" wide x 3/4" thick without the base. Drill the holes the same as above. Then drill 1/4" hole in the center of the back top. Use a 1/4-20 bolt to lock the circle cutting jig to your workpiece. Determine radius, and adjust steel rods. Rout!

Have fun!
