How would you do this??
Making a playing table using 3/4 ply. Drilled hole to start and cut 9 inch strip off of perimeter of sheet of ply, oval on each end. Covered center section with 1/4" foam and wrapped down around edges. This made center 1/2" too large to fit back into outer strip. Being foam I figured I needed an additional 3/16 off the inner side of the outer piece all around, which would allow for good fit with compression of foam. What would be best way to take off the 3/16 using a router. Arkwood
