Hmmmm, is there a reason that a 29" shaft including a wood ferrule would way more than a 29" shaft without a wood ferrule?
Dick
No, not really. Just the glue I guess. I guess my point is that if the shaft is already wood, why turn some off, then put it back on?
For me, strength has not been an issue at all.
Robin
BUT the ferrule is also the part of the shaft that we are willing to sacrifice. So a wood ferrule can be used as a light material that holds the tip, and also can shatter without damaging the tenon or shaft that it is glued onto. I have a stacked wood ferrule that I made from some laminated shaft material. The laminations are oriented at a right angle to the shaft center line. I have been playing with it for about two years now on a regular basis. I find the hit is great, and I have had no failures. I even ocassionally have used it to break with, though not as a habit by any means. I glued on a fiber pad on both the front and the back. The pads set off the ferrule nicely and give it a finished look. If anyone wants to see a pic of it, let me know.
That's interesting. Is there an advantage over no ferrule at all?
Kim
Yes. The reduced tip mass makes for very little deflection and no durability problems that I've seen. I've even done without the pad by treating the shaft end with thin super glue to toughen it. I don't use thin tips, so I've had no trouble at all, and the shafts shoot very straight. I've been doing this for years.

In all fairness to OB we have seen ferrules made out of other materials broken also. The way they rotate the laminates actually makes it stronger than the shaft wood itself in my opinion. So had that same shaft, you saw with a broken OB ferrule, been a shaft with no ferrule and just a pad on it, you would have probably been looking at a split shaft. So the OB goal seems to be to keep the hit natural like there was no ferrule yet increase the strength and durability of the shaft.I have seen an OB shaft with the wooden ferrule broken. They don't seem very strong. I thought the point of a ferrule was to put something on the end of the shaft that was stronger and more impact resistant than the shaft itself.

OK.... so I wanted to do a little investigation of my own on this end mass theory....
I took a new threaded and capped titan ferrule and measured and weighed it.
Then I took an equal length piece of maple shaft wood and measured and weighed it.
titan .559 in dia (14.2 mm) 3.9 gm
wood .558 in dia (14.2 mm) 2.8 gm
So you are telling me that 1.1 gm that you save with a wood ferrule has any effect on deflection????
AAAHH ! you say but..... they are not at the playing size. Well doesn't the weight difference get even less when you turn both of them down to 13 mm or even less at 12 mm ????
Sorry, but I seriously doubt there is anything to gain from a wooden ferrule.
(this is just my own opinion..... no disrespect intended)
Kim
I lean toward your way of thinking that the little weight difference between various ferrule materials effects the hit of the cue even enough for the robots to prove it. The 1.1 gram figure difference is actually high. Because you will drill a hole into the ferrule eliminating around half the weight of the ferrule. So the actual difference would be more like 1/2 a gram.
The ferrule material does effect the hit. But it is not the weight, but hardness and properties of the ferrule material itself that changes the hit. Various plastics, wood and such all play, feel and sound differently. The method a ferrule is installed with also changes the hit. But a threaded and capped ferrule or one with the hole going all the way through provide so little of weight difference that I seriously doubt it changes the hit or deflection solely from the weight difference.
By the way, I was unable to weigh the superglue I used on my .001g scale, so it didn't add much weight.
