Foam...

Build one and find out! Dr. Dave has a page that explains that end mass is the major factor in determining cue deflection.
When you have nothing to answer regarding the question, you abstain, this way the thread does not become ridiculous.
I have built quite a few shafts, where about 1/3 of the shaft from the joint have a denser foam, then a lighter foam in the rest of the shaft. Does it make a big difference? Not really, but it does change the final weight and balance somewhat. I second @kling&allen suggestion about testing it out for yourself, so you get a first hand experience. Build two shafts where everything is the same except for the foam and do a A/B comparison and let players and friends you trust try them too.

True to form, you have nothing of value to say regarding the specific question about the rigidity of foam but you comment anyway, you tell me to try it for myself, imagine I thought about it without your help with that, but if I ask the question here, it is to find out if anyone has already experienced it.
I gave you a lot of detail mate. But if you want to know what density foam I used it's a combination of 2 lbs and 4lbs. On break and jump shafts I use 8lbs and 2lbs.
As I commented before on your posts, myself and others take time out of our day to answer questions and the temptation do continue to do so really diminishes when I see passive aggressive responses like the one you just gave me..
I spent a lot of money on tubes, foams, glues etc. And I did a lot of test shafts before finding a solution I was happy with and felt could compete with other commercially available products out there. I'm not about to give you a detailed step by step of how to make a carbon fibre shaft, but I have given you plenty of information and clues for you to use.
All this has nothing to do with my question, learn to read. The density of the foam has nothing to do with stiffness.

No need to be a complete ass on the subject. No one is going to give you a step by step approach to this. This will be a trade secret, experiment and find out, just like the many others have done before.
You too learn to read, I never asked for a way to do it step by step.

I can read experiment a find out
You are reading my responses like the devil is reading the bible..
If you have two shafts, where one is very stiff and the other is flexible that's mostly a feature of the carbon fibre wall thickness. I like the ones that's about 1mm in wall thickness. Does the foam density add to the stiffness? Marginally would be my answer.
Ok, and if no questions were good to ask, what use would this forum have, in particular this tab called: ''Ask the Cuemaker''.
Kim really did give you some answers right from the start. He told you it does not make much difference. But then you attacked him. I am guessing you have history that makes you easily annoyed with him and others on here. I have personally used factory foam, my own spray foam and styro-foam packed in with a rod and acoustic foam packed in with a rod. I do not have a robot to check deflection, but I can tell you that some factory foam fills make a noise that I don't care for. Packing strips of acoustic foam gets rid of the vibration and noise as good as any factory foam I have tried. So I would guess your concrete like foam you are referring to is the stuff that makes the noise I do not like. So pliable foam has a better feel to me than the super rigid stuff.
I made a test.shaft out.of 12.8mm hard foam filled blank.
I was tempted to remove the foam.the first 5 inches. It didn't seem low deflection to me.
I gave it to a friend instead.
After making quite a few shafts and also repairing most production shafts, I have noticed that most players prefer the shafts that are filled all the way to the ferrule as opposed to the ones that hollow and partially hollow.
You tell me that Kim Bye answered my question and I then attacked him, that's totally false. I asked a specific question about the stiffness of the foam and he answered something completely different, telling me about the different combinations of foam density he had tried. Is it so difficult to understand that rigidity is not density. Kim Bye always answers what suits him no matter the question, it's really hateful, it confuses the real question asked.

Dude you need to relax. Hateful? are you really sticking with that statement?
I have answered your question from several different angles now. You should have a wealth of information in order to make your own shafts now.
I am perfectly relaxed, when you have nothing specific to say in relation to a specific question, pass your turn, at least on my threads, I hate your way of doing things which changes the very direction of the thread, you still need a minimum maturity to understand that.
