I've had different length points, forearms, and buttsleeves from the same maker, even with equal length butts. I've got two 58 inch Joss cues, one very early, probably late 60s, the other, 1976. The early one has a longer handle and longer points than the 1976 one, very noticeably.
Could be conjecture, but I think it's fair to say that cuemakers of that era ran into issues with wood and such, and adjusted as they went, with the making of a cue.
Yes indeed. But these aren't so old.
It looks to me like they have 2 or 3 dimension sets they work from for these. Of course there would still be variation.
These cues span from the early 90s up to about 10 years ago by the way.
So what I am saying is that in their production they probably have sets of jigs and templates for the design and build off that at stations. We know they work at production stations. So there is a degree of consistency with variations.
On the top cues, the ones on the right, the rings line up. And the points are even. That's assembly and QC. They are the more expensive cues. The cues one the left, the Cobra cues, have the most variation in consistency of their construction. Rings don't line up, and points are uneven.
Beyond that though, the dimensions of the butt sleeves, handles, and forearms seem to run in sets and are consistent among a particular brand. So, it seems a particular set of jigs and templates might be dedicated to a run for a brand.
Just the musings I have based on what I have seen. Lots I don't know or have any idea about but it's fun to consider the possibilities. In any case these cues definitely display the spectrum of quality available short of the best KaoKao has made. The best are challenging to differentiate from the best Adam/Helmstetter made.
