I have been considering building a plane board. I have began to wonder if I should modify it for TGM. From what I can tell, the semi-circular part cut of the middle to allow for the address position usually has a radius of about 30 inches, leaving 18 inches on each side for the club head and part of the shaft to rest upon. I'm wondering if I should reduce this radius to just enough to allow me to take an address postition. My thinking is that this would allow me to not only rest the clubhead and a small portion of the shaft on the board, but the entire shaft and even my right fore arm and elbow. From there I could be sure that I am going up plane and back down plane. Comments or suggestions?
