BIG Butts and BIG Joints

Most of my "old school" cues have noticeably larger dimensions than my newer cues and I'm not sure all the changes they have made in today's cues make them play any better than old school cues.

I have an old A. E. Schmidt Titlist conversion (full-splice) with a butt that is humongous compared to today's cues and I think the joint isn't quite as big as most old school (I think it is around .835-.840). The butt has to be around 1.30 or larger, since it won't even fit into my normal cases. The wrap area is larger than the butt of today's slim cues.

I read the following on a cue maker's website and was wondering how many cue makers on here share the same ideas about pool cue dimensions. _______________________________________

Yes, the size of the joint matters, at least on a cue. Smaller joints permit the cue to flex much more than larger joints. Depending upon the hit and the mass of the cueball, that flex can become uncontrolled buckling. In any event, the more the cue flexes, the more energy from the stroke is absorbed by the cue rather than being transferred to the cueball. A larger joint means less flex where it is unwanted and more control of the stroke by the player. The most common joint diameter for piloted joints is .840 inches, for flat-faced joints .850 inches. Some production houses and a few custom builders go so small as .830 and .810 inches. Butt diameters are dramatically smaller than 50 years ago when they were commonly 1.30 inches. As cuemakers began to adopt phenolic tube materials for joints and butt caps in the 1960’s and 70’s, they found that most phenolic tube stock was in standardized diameters, e.g. 1.25 and 1.50 inches, because those were sizes that the principal market for phenolics, structural and electronics manufacturing, desired. Cuemakers initially didn’t command a large enough share of the market to support producing tubing to their particular needs. Using 1.50 stock was wasteful, so cuemakers, production houses in particular, marketed the concept that a smaller butt diameter, 1.25 inches, somehow made the cue play better and was certainly more stylish. Even when phenolic manufacturers began to produce tube sizes specifically for cuemakers, the smaller butt diameter remained because manufacturing processes were already standardized. Thus, most cues reflect an “as built” compromise heavily weighted to manufacturing technology rather than player ergonomics or cue performance.

For the most part the tale may be true except for the available sizes of pheno tube
being the determining factor in today's cue dimensions. It was stated that 1.5" was available.
If that were the case, any desired diameter smaller than 1.5" could have been done.

Well, I wasn't building cues that far back, but I don't think the phenolic market has changed that much and I can assure you that the plastics industry has no interest is special products for pool cues. My suspicions are that the 1.375" sizes that are commonly used today were available then as well.

Now, as for the joint size and the comment about energy from the stroke being absorbed by the cue ball so it can't be transferred to the cue ball just doesn't work. Keep in mind that the tip has left the cue ball long before any vibration or flexing of the cue can make it to the joint area. Given that, how can the forearm flex affect the energy transferred to the cue ball?

Don't get me wrong, it''s a very common misconception. One that I used to subscribe to as well. But as you learn, you have to be able to challenge your previous conclusions.
