DIY Porter-Cable Mounting Plates

Lay the acrylic plate on a flat surface. Place the yard stick over the acrylic plate from corner to corner. Mark the acrylic from corner to corner with the black marker, using the yard stick as a guide. Move the yard stick to the opposite corners and mark the acrylic again, creating an X across the corners.

Mount the 2-inch hole saw drill bit in the drill press and tighten the chuck. Safely mount the acrylic plate on the drill press table using clamps, centering the plate under the bit. Drill the acrylic with the 2-inch bit all the way through, creating a hole. Remove the clamps from the acrylic and brush away any remaining particles.

Remove the bottom plate from the router by using the screwdriver to extract the 4 screws. Place the router plate on the acrylic plate, lining the 4 holes up with the black lines on the acrylic. Using the marker, mark the acrylic plate through the holes making sure to create a visible dot.

Mount the 3/16-inch drill bit in the drill press and tighten the chuck. Using the 3/16-inch bit, drill four holes in the acrylic where the dots are marked. Clear the acrylic plate of excess particles. Set the router, upside down, on a flat surface. Set the acrylic plate on the bottom of the router and align the 3/16-inch holes with the original holes in the router body. Place one screw in each hole and start by hand. Tighten the screws snug with the screwdriver.
