Custom pool cues huh? I love to play pool, have been playing pretty seriously for about 8 years now, but have never had a decent cue of my own. I have thought about making a machine for cues...not that I want to make them ofcourse, just the machine! A few questions. What are you planning to use for bearings? What size rods for the ways? what is the travel? Why do you need to have 4 axis {a machine like this usually has only three, X(the longest axis), Z, A}? Why steel (I am a steel fabricator myself just curious)? Other than that it looks good.
