So I worked on my eurobrace all day. First cut, I asked my wife to help me hold something. Needless to say that didn't turn out well so I had to eurobrace from the inside diameter. After cutting out the center I over cut 1 corner by 1/16th of and inch. I tried trimming it down and kept trimming since my clamps and flush bit decided to fail on separate occasions. Now if left with no eurobrace and not enough acrylic to try again. Still weighing my options
