buzz in cue

What are the opinions on what causes a buzz in a cue...I don't mean when shooting with it, more when whacked on the side with the heel of the hand. I see this once in while and even saw it yesterday on shaft that I made, before the ferrule was even put on. I know I did the insert well and there was no loose material in the insert hole. I've even seen it on shafts with wooded threads (where there is no glue at all). Just vibrations???? I'm sure that the shaft isn't cracked.......

Tuning Fork

Mike,
I'm not a Qmaker so take with a grain of salt. If there is no signs of a crack then it could be that the shaft is very stiff and is acting like a tuning fork? :confused: Just a thought.

Try to isolate the source of the buzz. Find a cue that does not buzz, place that shaft on the butt that is buzzing. Test for a buzz, if it does not buzz, then put the buzzing shaft on the quiet butt. This way you may be able to determine which of the two pieces is causing the buzz. If it is quiet both ways, then check the mating surfaces at the joint of the original two pieces. The source can be hard to find, because the vibrations can travel and sound as if they are coming from somewhere else. The buzz is probably in the "A" joint if I had to guess.

Anything buzzing has to have either a crack, gap or loose parts I would think.
 
I use some old house cues for low end stuff...higher end or with exotic hardwoods, I purchase the blanks. I have some customers that want a steel jointed cue for under $250.00. This about the only way it's still worth my time. I've done steel pins at the "A" joint using glue relief and never seem to have a problem there. With this cue it's definately in the shaft. Not much time or money into it yet...it's going to get a visit with Mr. Bandsaw if I don't figure it out.

Hi Mike....Striking the cue on the side with the heel of your hand causes more severe vibration than striking the cueball. I suspect the noise may come from the faces of the shaft and butt joints rubbing together. Try dabbing some shellac on the face of each joint, just enough to wet it, then wipe dry. This will give the joint faces a bit of tackiness and they will grip and lock together more positively, and should eliminate the buzz, if that is really the cause of it.

Rechecked where the joint faces meet and they weren't connecting properly. I switched to a new tool with a carbide insert to do the facing operation and now I'm noticing that it's leaving a slight radius where the insert goes into the joint collar....preventing the shaft from seating down all the way. I've gone back to the old tool and it fixed the problem. Thanks for the input.

Buzz :could be different things if it has a brass incert in the shaft check to see if it faced off smooth A lot of time people over look this happen to me a few times with my viking cues or could be weight bolt,tip,ferrule,tendon or worse ware the wrap and the handle join together.

Good call Paul! One other thing I'd check first off is if the facings of the butt & shaft are good. Sometimes it's evident if you hold it up to a bright light. Often re-facing both parts clears up the buzz.
