Coring

Maybe something like this happened:

Me - "What's between that wrappy bit and the top part of the butt"

Cuemaker - "There's a joint between them"

Me - "Eh? What did you say?"

Cuemaker - "There's a joint between them"

Me - "I'm sorry, I didn't quite catch that, it's your accent you see"

Cuemaker - "A JOINT! I said A JOINT! Now stop bugging me with all your questions!"

Me - "oh, an 'A' joint. I see..."

:thumbup:

Or maybe there is a 'proper' answer?
 
Yes the A joint is where the handle and forearm are screwed together. I have no idea why it is referred to as the A joint. Maybe someone else can add to that.

I think that it probably goes back to the cues that had various joints and sections that would unscrew. Like the old 6 piece cues. In Engineering if you have multiples of something, in this case joints, you can use something like letters to label them. It apears that the main joint, or normal joint, just doesn't have a label normally and then for every joint after they just gave it a letter value to keep them straight. So "A", "B", "C"...ect.
 
What wood do you core with?

Have any of you used laminated dowels to core with. Specifically, hard maple laminated with ebony? Seems expensive to use Ebony but I know a cuemaker who is currently building a cue with two pieces of maple and ebony sandwiched between them used as a core dowel. What do you think?
Thanks for your response.

Cue makers use maple because it's strong yet inexpensive. Laminated maple dowels are (supposed to be) even stronger. I've used lam dowels. They're just fine. I personally think straight grain maple is just as good and is a little cheaper.

But you're saying this guy is using hybrid laminated dowels made of both maple and ebony? I'm assuming he makes them himself? Sounds a little over the top to me, but what do I know? *Wow!* If that's what's going INSIDE the cue, I gotta see the outside!

I thought I was a little cooky for making sure the grain of the core is 90 degrees to the grain of the cored wood when I glue them in.
 
Does anybody know if cuemakers use cores that are from one single piece going through the complete butt? A plain jane for example can with a core like this be made with the feeling of 1-piece cue. I personally have such a cue, and the core through the whole butt is here a multilayered construction. It was an experiment, i made the core by my own and a cuemaker of Germany (Cem) built the rest of the cue. It has a strong hit and perfect sound, with plenty of feedback.

The combination of different woods inside the cores, like before mentioned ebony and maple, helps for sure to put the weight into a distinct range, or you can also compensate low weight woods, used at the outside. Just my understanding.

Hi,

I do but I am not the only one who does full coring. There are a lot of guys that use this method.

Forearm points installed on the core. The rings, handle and butt parts are slid over the dowel. Expanding poly glue is the answer here so that all void annulus spaces are filled solidly.

A few do it .
My opinion is a two-piece jointed core is better b/c you have two contrasting woods tightly mated ( in compression ) and have a weight addition in the middle.
We know from guitar construction, contrasting woods make for better resonance ( backs and bodies are almost always different woods ) .
Some additional weight in the middle as opposed to just on top and bottom make for a better balance too imo.
This would be easily tested too.
If you bounce a maple shaft with 2 oz of weight added ( top and bottom ), compared to a maple front with a rosewood dowel in the rear and some weight to get to the same weight as the weight-added maple. The maple with rosewood will resonate better.

Hi Joey,

Just curious, what does "resonate better" mean? By your suggestion one might think that everyone who plays pool wants to have some type of selective resonance ideal. This I know is not the case and is especially true with ferrule selection for example.

Balance is a function of physics not "better balance" and compared to what? Balance in a cue is a function of a CG. This is dictated by a fulcrum, moment arms and cumulative distances fore and aft with in an envelope.

I have never tried to make a ball to win or lose a match using a guitar and I have been playing one for over 50 years. The thought never occurred to me that a guitar and a pool cue had anything in common especially in design construction.

The guitar comparison does not qualify for any type of null hypothesis as there are a lot of players that seek and prefer a soft or quiet sound that maple is so famous for. It would only make sense that a 3/4" dowel running through a cue would be good for that type of player but is totally subjective in selection. Quiet or high pitch resonance, there is not better, just different.

I concede that there are many people who wish to hear a ring tone when they hit a cue and that's is a great ideal to strive for in your cue engineering. Since the shock wave that occurs when striking a ball is through the cue is milliseconds any feedback that a player's nerve sensitivity can detect is doubtless auditory only but I could be wrong on that one and will stand corrected if proved otherwise.

IMHO, no way is better, just a different flavor.

Rick

Notice how I did not bring up the fact that coring is better because cored cues are less likely to warp. That's just my take on it , I am not saying better.

If that's the case, why pick the best sounding shafts then?
You can send me all your pingiest shafts and I'll send you my dudly sounding ones but they will be straight.

True. But, I'd still want less weight behind the pin and put some in the middle of the butt if needed. And least at the bottom too.

Compare a full maple butt to a chopped house cue with purpleheart bottom.
Make them at 15 oz. Which do you think will get more votes from them as the better hitting one ?

They don't need to hear it. They need to feel it. You can surely lower the deflection of your shaft by drilling a hole on top but that will kill the hit and tone. Since the shock wave is only milliseconds, it shouldn't matter, right ?
I strive to maximize the feedback to the griphand. Muscle memory is funny but I want the player to feel how he hit the cueball.

I didn't say none cored cues are better.

I made a kick ass shaft from an old house cue. I use that shaft on my playing cue. It makes the most beautiful ponk noise. On my rosewood sneaky its a nice soft ponk. On a purple heart sneaky butt, it makes a loud, crisp, sweet ponk! Some say the butt doesnt matter, but like Joey said, different combonations of wood resonate better. Now whats better for me, might not be better for you. I know a few guys who want their cue to go thud. No ping, no ponk, nothing but thud or click. To each his own, but for me, i like the feedback i get from the noise and vibration.

I have had cues that just go "splat" like there is a pillow on the end of it. I have had cues that have a nice thud and I had one that went "clank" every time you had a center hit on the cue ball. My opponent kept asking "what's that noise?"

Because "its just pool" I don't think there has been much real scientific investigation on to why the sounds of cues are different.

Does it make the sound or not because.....

Is "tone wood" a real thing.

Does one particular wood sing/resonate more that another or do certain combinations do it more?

The woods are the same in the shaft and butt and it all sings together?

There are woods of different densities and the shock/compression wave is reflected at the joint of the different woods?

Is the noise in the shaft... the butt , or both?

Does the type or size of the joint screw do anything except hold the 2 halves of the cue together??? I talked with an excellent player last night and he swears by the radial pin. I honestly cannot tell or feel any difference between any of them.... maybe I just have a "dead hand".

What affects the sound the most? wood, tip, ferrule???

Should we throw away the bumper?.... it was sold originally as a vibration damper.

OR..... should we say "who cares", and just play pool????

Im not near smart enough to answer your questions, lol, but i have a love affair with purple heart. Ive only hit with one or two purple heart cues that didnt have a great tone to the hit. I just made a coco sneaky and it has almost no sound to it at all, just a thud. It plays as well as any of my other cues, but it doesnt resonate like that trusty purple heart. Its the same pin, same shaft wood, same ferrule material, and same tip as most of the rest of my cues, but it doesnt sing. Someone will like it, but id rather play with a house cue, lol. Im not much of a player, but if my cue doesnt sing, i cant get that outta my head, so it interferes with my game. I know, i know, i should be able to block it out and focus on the shot, but i dont have that kind of mental toughness when it comes to pool, lol.

Joe
 
I'm glad this thread has not died.

The construction and timbers used in the whole cue make a massive difference to overall feel and playability.

It's been very interesting reading your thoughts.

I made a 60 in cue for a very good league player. It was coco/CM and I cored it with PH because he wanted it 21 oz. It has a Juma ferrule and a lepro tip.

Everyone that has tried it says it has a great hit. I think most of the feel is in the med hard tip and ferrule. but that is just me.........

Not many cues really sing. I think some of it is attributed to where you are holding the cue and how tight. Get a steel bar and hold it exactly in the middle with 2 fingers. Hit it on the end with a hammer and it will sing. Hole the bar off center and hit it. I will not sing. You have to be holding it at the zero crossing point of the standing wave that you generate in the bar with the hammer. I think some of the same applies with cues but the zero crossing point changes because of taper, the combinations of wood used, and where the joining sections are.

Hey Joey,

After reading your posts over the years I understand that you pay a lot of attention to detail concerning ring tone in your cues and the wood combos you use to make your cues which is noteworthy and Joey cues are known as great playing cues to say the least. I also understand that your have a very special joinery method for your A joint connection the you have perfected which requires a lot of extra time a effort to produce. These are just some of the things that makes a Joey cue selectively what it is and I am sure you have a lot of other great fine tuning things in your repertoire.

To say you and I or other full core guys are at two different ends of the spectrum would be an understatement. When we both put our point of views out there in the forum you and I have disagreed from time to time to put it bluntly but through those interactions I known I have grown a little by hearing your feed back and I hope that I have done the same in a small way to reciprocate in your direction.

With that being said, I wish to get back to the subject at hand and give my response to some of the new observations you have just made. Not to knock them at all but to act as a counterpoint an offer my point of view and take on the subject.

"You can send me all your pingiest shafts and I'll send you my dudly sounding ones but they will be straight".

My friend and neighbor John Wright gave me DPK's book about cue making and I studied it over and over. John had sold me my first cue made by David in the mid 80s and even a hack pool player like me could understand how good his cues played.

Part of what I learned about cue making from that book is that shaft wood should be culled and selected by buying planks and collating them for a variety of features. I feel that density is the biggest singular feature element in that selection. Type of grain cut, no run out, clearness, and straightness without crowning or bending can all be present in the 5/4 kiln dried planks I inspect but if it is a light board and not to my specs. concerning weight I reject it.

I can go through 100 planks and get 2 or 3 pedigree planks or I can go through 200 planks and get 1 or two only. Last month Darrin went through a bunk of 200 and only got one. That is the randomness of this process. Then seasoning them in a tapered form for years before they are matched up for a pair. I remember Eric posting about how he talked to a wood milling expert and he told Eric that quantity supplying the type of high quality maple that he specs. for his cues would not be possible as it is so hard to come by. That's why I go to my source after they get new shipments in and browse the bunks. It is the only way as far as I am concerned.

After doing all of this I will make no bones about it, I could care less about how one sounds compared to another and truly believe that my process control will give my end user the absolute best opportunity to get a great playing shaft that I know will be at least 3.9 oz. or I will reject it. From the time I dowel each shaft I know and have a chart that tells me what a 10.8 oz dowel 30" x 1" dia. (for example) will weight at my final taper but sometimes that can be off just a little because as you know we are working with wood. My rejection rate is about 6 or 7 % doing it this way. When you think about it when a shaft producer gets random planks and produces dowels what are your chances of getting select pedigree material. I can see why culling by ring tone could be useful for finding playable shafts.

So my answer to your offer is no, I would never trade shafts with anyone. And if your process is to cull your heard by using a tuning fork or your selective ear, I say go for it and I know in the final analysis you going to put out a kick ass cue because I know you care very deeply about it. If you are buying your shaft wood precut from a shaft merchant I would suggest to you as a friend to try my method I copied from the master himself, DPK. IMO buying shaft wood any other way is like getting a dog from a puppy farm. Sure there will always be some good ones in there but for the most part it is a pig in a poke.

True. But, I'd still want less weight behind the pin and put some in the middle of the butt if needed. And least at the bottom too.

Since this thread is about coring and you bring up the subject of weight, I would like to sound off in this area. When I first started building cues and was faced with making a cue out of different material and want to land the butt at lets say 14.5 oz., I would compensate with my A joint bolt at 1/2 by 13 tpi in steel because I found that most of the cues were always a little light unless I was using ebony or other select heavy woods.

I made wood specific gravity charts and calculated the volume of my final taper to try to have control over this process. When someone ordered a custom cue from me and wanted a certain weight I was as nervous as a whore in church because my cues are forward balanced by design and throwing a weight bolt in the back to load up a cue to make weight makes me sick.

After going to full coring all of my cues, I never give weight and balance a single thought until the cue is at final dimension and I am ready to install the pin. Then I just put the cue, shaft, joint pin, rubber bumper and some weight on the scale to the weight I want after adding the wrap and finish values. Now it is an easy job thing to install a 1/2" x 13 tpi weight bolt (I have 1/4, 1/2, 3/4, 1 and 2 oz. in stock for this purpose) threaded and epoxied behind the pin and glue up an insert in front of it to be taped for the joint pin. The rear weight is not to load up the cue to make weight is just for compensating the balance point to the area I want.

I don't know why you are so against a small weight up front. It's not like it is a LD Shaft or something. When you are fully coring you have to add weight because you don't have an A joint weight. Putting it in the back only does not get the job done but the cue becomes back heavy.

BTW, I will share some info I have gained from my good friend Stew Mortson who is 88 years old and has been around the block in our biz for many decades. He lived in North Hollywood and set up Red Baker's lathes in the 60s, worked as a master panto artist for Bert Schrager when he busted into the Japanese market and just finished his career here in Palatine after ten years when Ray Ray Schuler passed. Stew knew Harvey Martin and told me that not only was Harvey the first guy or one of the first guys to go to the flat face joint and big pin exclusively but he routinely placed a weight behind his joint pin to balance his cues. Only an insider would have known this and it is from Stew's mouth to our ears. Back in the day these old timers were very protective about there shop procedures.

I just found this out recently as Stew hangs out 3 days a week at my shop as he can't play golf now and revealed this after talking about the subject in depth.

IMHO, if you are going to core a cue from stem to stern, you must face the issue of weight and I believe it is mandatory to use a forward weight to control the balance and CG with the back weight as a compensating bolt if needed. When ever I can, I don't use the back bolt at all but still drill and tap out the pocket so the player has the option to go heavier and since I produce cues that are forward weighted about 1 to 1.5 inches more than the average CM, that player will not back load the CG if he does add a bolt at some point in the future.

Just my take on it.

Rick

Anyone who wants a copy of David's book on Cue Making, PM me your email address and I will send you a PDF copy.

A Joint with 1/2 13 tpi x 3" to make the weight when I was doing many A Joint Cues before coring everything. This was my last A joint cue made.

Even when I was doing A Joints I still cored from the A position back before I started cutting point grooves on the core.
