Your router will work fine. Since you're going to use a router, you don't need the plug cutter, it's for use in a drill press. Just go to a hardware store and buy a carbide tipped straight bit, either 1/2" or 3/4". The shield sets on the ball, set the bit height to cut about half the plug off the first pass, then I try to get within 1/32" or so on the second pass. Just work the router around until all of the plug material is cut level. Then finish off by sanding on your spinner. If you have to drill holes in the shield to fit your router base, be sure to support the shield so it doesn't flex as you're drilling, that can cause it to break. It may help to put masking tape where the holes will go and mark the location on the tape. -- JohnP
