I don't disagree that cues are designed for the primary force encountered to be linear. But the kind of force that I am talking about is not sufficient to cause a buzz that did not exist before. In fact, if such a force would, then the cue was deficient in materials or design.
The kind of force I am talking about would be commonly encountered by any cue in regular use. I only suggest looking for it in a cue that is being flipped, inspected, or not regularly used for some reason. If you were to use such a cue regularly you would encounter the buzz without purposefully striking the cue from the side.
No disrespect to any cue maker, but if the smallest of lateral force causes damage to a cue, that cue was not made well anyway. Such a cue would in fact not even be suitable for normal handling and/or play.
The first example I ever encountered was the JOSS I mentioned. It was for sale about 22 years ago. The guy let me try it out for a little while at the Cue and Cushion on Rt 51 North in the South Hills of Pittsburgh. The price was great, so I asked him why the price was so great. He said it had a buzz. I told him I had not felt it. He took the cue and lightly struck it on the side with the heal of his hand. The buzz was small but obvious. He said that he had tried it before he bought it off a guy from out of town and paid quite a bit more for it. The evening after he bought it he played several hours with the cue and every once in a while he thought he felt something odd. The next day he took it to Mottey's shop and told him about it. Mottey picked up the cue, lightly tapped the side, and demonstrated the A joint buzz for him. He checked the weight bolt and joint collar to make certain they were not the culprit then pronounced it confirmed to be an A joint buzz.
So, as the story goes, I indirectly learned it from Mottey, who was a cue maker of some substantial reputation by anybody's estimation. Of course, I got that story second hand, so it is entirely possible it is complete BS.
That was the first time I had ever experienced an A joint buzz.
As I said, no disrespect intended and I don't want to contradict more experienced people. I am just relaying my experience and where it originated. Mottey's actions and/or involvement could be complete BS for all I know.
