Broken pool cue

knocked the butt plate off a D-series, McDermott, on a break but it came apart at the glue joint. Mike Gulassy refinished the cue and said it was a manufacturing defect.
What's that glue line at the crack? Do you have more pics?
Yes sir! And you can even break with it. I’ve been breaking with my D-2 since 1984.

Looks like a worm hole.
I'm still trying to understand how the stick knows it is a break shot and not a long bank hit equally as hard. Does the cue ball somehow communicate back to the cue that it has collided with a tightly packed group of balls and not a cushion?
Is that cue handle made out of rotten wood?
Wtf maybe termites got to it. Lol. Your better off to buy the cheapest viking joss mcdermott jacoby. My picks for best cheap cue
....like the first cheapest model they make in USA is viking and joss. You could have bought one for maybe 30$ more than that players and the cue would last your lifetime

Balloons on a dead street corner I guess
Got this one in the shop a while back, haven't got around to fixing it yet. McDermott "Tournament of Champions" cue. Was not abused. Let it slip through his fingers and hit the floor and just popped. Must have had a stress riser and hit just right. Didn't help that there was no bumper in place. First one I've seen do this.... not the way I'd attach the forearm... surprised to see it in a McDermott.
You can see that the screw hole is way deep, and there are defects in the wood. I will contact a Players dealer and point this out to see if there is a path forward toward free replacement. Unfortunately, the logo looks like it is pretty old so it may be an uphill battle
I would buy it as-is to repair also

Three stress risers within an inch of length.
looks like this one: https://seyberts.com/collections/players-cues/products/players-g4118-pool-cue?variant=41732594630854 same butt sleeve design
termites
You'd think huh...
Skews me for not knowing. What is a stress riser?

A stress riser is something in a design that causes the effects of forces to be magnified. Common risers are sharp corners on a step in diameter of, say, a motor shaft. In the cue above, they stepped down in diameter at the points, have a tenon going into the forearm, and have the pin stopping shortly below that.
Stress risers (or concentrators) disrupt the flow of stresses. Changes in geometry, but also changes in material.
Even though those parts were all glued together well, the changes in geometry and material all multiply the effect of any applied stress.
One of the interesting things in both of the broken cues if that the wood breaks through the center of the end of the steel pin. This is interesting, but not surprising. The steel pin carries the forces to its end, where the worst of the stress risers occur. In both of these, the break goes from the a-joint to the end of the pin... So they go from stress riser to stress riser.
You will notice that from my description, it is impossible to make a three section butt without stress risers. The key is to identify them and mitigate them as much as practicable.
As I said, I had a couple very early cues fail due to the same thing. I was fortunate that I was a mechanical engineering student at the same time as the failures--it really made those classes sink in.
Very enlightening. Thanks.
One more question, how would you mitigate what seems to me to be a standard function of cue construction?
