I would guess each cue company has their own specs regarding the process they use. I doubt that the intervals they use are anything close to what a small maker would use, but who knows. If you are mass producing cues and have the space,equipment and people, the first cue out the door might take a year to produce, but you would have thousands of cues in different stages right behind it. Depending on the size of your operation, you could ship 100's of cues weekly. I was stationed in Japan back in the mid 80's and lucky enough to meet Dick Helmstetter at the Adams' plant. He toured me through, it was really small, with about 12 employees, maybe 6-8 machine lathes. We went into the "shipping" room and there was 2 ladies there packaging up about 20 cues. I don't have a clue as to how many cues they were producing, but at the time that I was there, I was surprised at how small an operation they really were.
