How to Make an Angle With a Routing Jig

Place the angle jig into position over the surface to be cut. Manually adjust the jig to the desired angle. Measure the distance from the widest edge of the router bit to the outside edge of the router’s base and offset the jig from the cut by this amount to ensure that the cut is performed in the correct location.

Clamp the jig to the workpiece with wood clamps. Ensure that the clamps don't interfere with the path that the router will take during the cut. If the cut will penetrate the entire thickness of the workpiece, clamp a piece of scrap plywood beneath the workpiece to serve as a buffer between the router's bit and the surface of the workbench.

Set the plunge router against the jig and position where you want the cut to begin. Pull the tool’s trigger to turn it on and press down on the side handles to plunge the router bit into the workpiece. Flip down the plunger’s locking arm to lock the bit in place once the desired bit depth is achieved.

Push the router along the jig, ensuring that the router’s base remains in contact with the jig until the cut is complete. Once the end of the cut is reached, release the tool’s trigger and flip up the plunger’s locking arm to raise the bit out of the workpiece.
