Thanks to Austin Roche and Nick Heys for CAM and for reviewing my designs.

A special note: this machine was inspired by Travis Wuertz's TW-90 grinder. I used many of his excellent ideas, and built upon them. During the process, I gained immense respect for the man - and the work that he put in making his grinder what it is today. I am truly standing on the shoulders of giants.
