Benny, Ed is no longer with the forum, he has been gone a long time. This is sad because he was a wealth of information to us all.
Remember this is for a palm router, not a full sized router like yours. The plastic will flex with the weight of your router. The router centering kit Ed mentioned is from Rousseau. It includes the centering disk, 1/4" centering pin and the correct size and number of Allen transfer screws for your router. You can order these online from Woodcraft.
