It is a 2 sided job...I started with a 4" x 4" x 2" block...used a 1/4" spiral cutter for roughing out the top half of the ball, then a 1/8" tapered ballnose bit for finishing, then a 45deg v bit for the logo...flipped it over and used the same two bits for roughing and finishing the bottom of the ball, then a 1/4" spiral for pocketing the hole...I threaded the hole by hand and inserted the heli-coil...mounted it on a threaded shaft and spun it in my drill press for finish sanding, then applied a clear gel topcoat.
