Looks great. I think he means what we discussed about the insert I told you about. It has a for lack of a word I can't think of right now a cupped cutting surface on top, very sharp edge designed for cutting soft material like aluminum. The flat top surface cutter you are using basicly forces the wood off the plug and causes tearing of the wood. The sharper edged insert actually cuts the wood, thus smoother results. I hope that is understandable.
