Mezz Wavy Joint

Hi together, yesterday I had a close look on my Wavy pin of my Axi cue. I was surprised seeing a very unusual shape of the threaded bolt. There's app. in the middle of the flank a line where the thread has some kind of a hog, the flank has a special profile. I think this hog is the main reason why there's much more power needed to srew a wavy system than at most other pins. By these hogs the wooden thread of the shaft is being compressed and as a result there is a "0"-tolerance connection between shaft and threaded bolt. Great idea!! I love it

I love the wavy system most of all joint systems that I‘ve ever used. I like so much the tight / stiff connection avoiding any loose fit.

Your English is difficult to follow, but I believe your logic is flawed. The tap used to cut the thread on the shaft size matches the pin, so there will be no "compression". The reason why it is a tight fit is that it's a proprietary joint and the same manufacturer (Mezz) makes the wavy pin AND the tap. With a non proprietary joint like 3/8x10, there are numerous manufacturers and the exact dimensions of the pin and the tap will vary a lot more.

Gimmick or not when tight they stay tight unlike almost every other 3/8x10 cue i've owned. I had two 3/8modifieds that needed to be tightened all the time. I know various factors/tolerances can result in un-snug joints but both shafts on my Mezz are super tight.

Better than radial?
3/8 10 or 11 flat bottom should not need to be tightened all the time.

The extra ridges might be untapped resulting in the high friction.

I have an original Wavy butt with two shafts, and a Wavy 2 butt. The Wavy 2 pin has the same major diameter, but a smaller minor diameter. My shafts are tight all the way when screwing on the (original) Wavy butt, but they screw on effortlessly on the Wavy 2. That tells me it is the minor diameter that creates the tight fit, not the threads.

So the lower ridges aren't scribed into the shaft thread?

Is the complete wavy profile tapped into the shaft or just a general trough? I'm trying to grasp the compression effect.

I have no idea. I haven't seen the tap myself. But I explained my observation with waavy and wavy 2 which indicates it is the minor diameter that gives the tight feeling, not the outer.

The flat bottom versions are just a gimmick. ;)

See how that works...lol

Not really.
Can easily shown by cutting a threaded maple .
Threads will show much better contact.
Wavy screw is actually the cheaper ball screw than the radial screw.
 
Is this better than rolled ball screw?

Sure, I'm indifferent...

Only thing I know for certain is that in all the years I've had cues go through my hands. The most snug joint pin I've had the pleasure of putting together is the wavy. That includes a large host of cues utilizing the apparently superior radial profile. I'm sure that's simply a product of tighter tolerances.

One of the joys of being naive is enjoying reality rather than fretting over theory.
 
Whats it matter guys? All that matters is it locates itself easily so you don't cross the threads like a some slackjaw. It stays tight and won't come lose during a game and doesn't wear out in a few years. Gimmick or not it works. And for the five seconds u spend screwing together your cue... It feels more premium than 3/8 10 modified or not....and radial....

I've said it before and I'll say it again. Mezz makes the best feeling joints (when screwing a cue together)in the United and the wavy.

Gimmick or not who really cares. If it's durable and holds tight. That's all that matters. Bastard pin? Who cares. I dont see a need to ever have any work done on any of my mezz cues. I've seen guys foul up their three eights ten and radial shafts.

Personally I like 5 16x14 steel joints. Never had any problems never seen any problems. And it's common so replacements or a loaner in a emergency is an easy find

I've never had a 3/8-10 come loose.

Snug, tight tolerance fit between male and female is counterproductive to the main objective of a joint screw... Which is to provide clamping force, which is decreased by friction in the threads.

One that hasn't been cleaned in three years heavy use. Still works and feels like new.(I should probably be more religious about joint protectors) looks kinda dirty. But ud never know without looking in the hole.

Ps that was hard to get a photo that good and it's still not good. Also mezz gets their hands on probably the best shaft wood out of any "production" cue maker that I've seen.

Why would it? The only ones I've seen come lose are QR. Talking with my dad. A few months ago He's had his radial Blackout carbon shaft breaker come lose on him a few times. He sold it. Not sure what the problem was. I didn't like that cue atall when I tried it....the butt felt like a cheap piece of crap and the thing would oscillate like crazy when smashing a rack.

I've never owned a radial joint cue So I can't really say anything about the joint.
