I'm cutting out the inside of a spoon 11/4" X 21/2". I'm using a 3/4" bowl router bit which will give the spoon nice rounded edges. The problem is the cut goes outside the perimeter in a couple of places. The rectangle works but at the bottom the lines go wider then the rectangle which causes the cut to go too wide. I've viewed the video on the pocket tool but haven't found a solution. When I use a 3/16 ball bit it works great.
