As an amateur, i don't make enough cues to be a datapoint.
Also don't make them yet for people i don't know.
However, if the maker has complete control over wood used, balance point, and dimensions, it's not hard (actually, easy) to hit a weight within a certain overall dimensions.
If you are using wood for visual design (rather than weight and other properties) and subject to a customer's specs for dimensions, wt, and balance point, it can take a little more thought and work but still do-able.
So far only had to add weight to one for a friend who wanted (he moved out of the country, this is from memory, so might be a little off) 63" long x 24 oz, 13mm tip, butt around 32mm . Design was up to me. I made a simple 4point fs sneaky. To add weight, had to use a longish steel 3/8"-10 joint pin instead of my normal G10 pin. Also did not drill the shaft as in most; though that is barely worth a few grams.
(Strange as that spec might seem, perhaps even more oddly was that women in the league were the ones who liked and shot better with it. All innuendo aside, probably because it moved like it was on rails, a person with a more hesitant stroke could find it stabilizing. )
