Highlights:

Step 1: Secure the Shaper Blades

Insert the shaper blades into the shaper holder. Use an Allen wrench to securely tighten their hex nuts.

Mount the shaper holder onto the table saw arbor according to the manufacturer's instructions.

Step 2: Replace the Existing Throat Plate

Replace the table saw's existing throat plate with the zero-clearance throat plate. Slowly raise the shaper blades to cut their own custom throat.

Step 3: Attach the Wood to the Fence

Screw the strip of wood to the table-saw fence, starting the screws from the side of the fence opposite the blades.

Step 4: Adjust the Fence, and Cut the Molding

Adjust the fence to the appropriate distance from the shaper blades. Adjust the cutter-blade height to cut the appropriate profile in the molding.

Slowly run the molding through the rotating shaper blades, using a push stick and an outfeed table, if necessary.
