I can tell you one of the ways I have done it. Attach your plate to a piece of 1/4" BB plywood,next use a 1/4"spiral bit and a 1/2" collar guide,template guide,or whatever its called and cut the pattern in the plywood. You now have a pattern that is a copy of your plate,but 1/8" larger. Attach this pattern to your table(double stick tape,nails, whatever works) using the same bit and guide cut the recess. You will have to accomodate the plate by cutting the approximent depth of your plate or using something similar to the plate levelers used by Woodhaven.
