What Causes a Pool Cue Shaft to Buzz?

I searched back 13 years and nobody seems to address this:

Why does the pool cue shaft buzz when I bump it on the floor or take a shot?

I don't see any cracks, but is the shaft hollow somewhere?

Not a dumb question at all.

I'm not 100% sure I am understanding your scenario, but I'll take a stab at an answer as to why a "buzzing" noise is coming from the pool cue shaft.

When you bump the shaft on the floor or take a shot it generates oscillations which vibrate through the pool cue and shaft.

I believe that the buzzing you hear is caused when the vibrations travel through a portion of the shaft that is beginning to delaminate.

The delamination may not be visible as it can be concealed by the coating on the shaft, chalk build-up, or general dirt, oils, and grime build-up.

Alternatively;
- I've heard folks complain about vibration noise coming from a joint pin and shaft insert connection that won't form a tight connection. Could it have been that?
- Could it have been a lose weight bolt? From another site:
  
  I know for a fact that predator uses a stacked weight bolt system, so it is possible for a lower bolt to be buzzing but the top one seems tight.
  
  and
  
  The Fury rattle sound was caused by weight bolt. We put some teflon tape on screw and tight it real good, so no more strange sound, we can say we fix it.
- Others have mentioned small pieces of hardened glue, compounds, or epoxy being loose behind the shaft's joint pin insert, and it rattles around when the cue vibrates.
- In one case it was the rubber bumper:
  
  The screw for the bumper was tight, but the bumper rubber was ripped horizontally and I didn't see it. The bumper looked to be fine, but when you hit with the cue it made the tear in the bumper "flap or vibrate" when the impact caused the rip to open and close. I replaced the bumper and everything was good to go.
- I've also read about folks complaining about loose ferrules causing a vibration noise.

Well it seems there are many more pieces to the anatomy of a pool cue shaft than I had pictured!

I wouldn't really be inconvenienced if I took a saw to it, but for now I'll give it a more thorough once-over.
