Tapered Carbon Fiber Tubes

Ran across this company.. https://dragonplate.com/roll-wrapped-carbon-fiber-tapered-tubes.

I don't know for sure if these would work for cue shaft blanks but it sure looks like they can, and at around $30. Likely they could make you custom tubes with a pro taper.

Thought this might interest some of you.

Probably not

Hard to say with the NC equipment these days but custom shapes for carbon fiber were ridiculously expensive in the past. A military R&D project to make a portable backpack air conditioning unit had a maximum weight of 22 pounds. Hard to meet that so I looked into a carbon fiber frame. Forty grand for the proto-type in '89 made from sections of straight tubing. with most of the curved shapes laid out the cost jumped to hundreds of thousands. The backpack frame alone could have been close to a million dollars.

If the straight taper would be right for european style shafts it might be interesting for those. My guess, fairly short runs of hundreds of pro taper shaft blanks are still impractical due to costs.

Their standard wall thicknesses seem to be 0.01 and 0.02 inches. That seems thin but I have no idea what carbon pool cues use. The diameters look about right. As Hu said, the taper may be an issue for some people.

Those are roll-wrapped.
The available shafts are layered uni/multi-directional fabric.
Much different characteristics.

Both types are mandril formed, and most can make a custom taper
if you can afford it.
A one-off would probably cost more than a complete shaft.

Read this and it sounds like your description to the t....

Whats the difference?... Is it the " multi " directional?

oldschool1478 · Dec 14, 2018

Here is a good example, of a multi-directional lay-up.
This is similar to Revo etc.

Yes but their description says the layers are "oriented" in such a way for stiffness and axial strength etc....

I wouldnt doubt if it was the exact same thing.

I'm with you.

I don't think these cues are "rocket science"...I have one.

Here's an old Predator patent, appears to be abandoned, whatever that means....

https://patents.google.com/patent/US20080064515A1/en

In short, the wall thickness of the tube might be varying from thinner at the tip to thicker at the joint in these new carbon fiber shafts to 'facilitate a more efficient transfer of energy to the cue ball'.

Anybody want to cut their's open to confirm?

It is not a patent, it was only a patent application. For whatever reason, Predator stopped pursuing the patent and it was never granted. (The number actually indicates that it was an application -- it includes the year of filing while the numbers on granted patents do not.)

somebody will damage one

Somebody will damage one and we will see what is inside. The reason I never jumped on the spliced shaft bandwagon, the splices were well off center in some we did see the construction of after they were damaged. I bought a flat laminate blank or two on sale very cheap to test. Still using one of those blanks. It is a decent shaft, moves around a tiny bit but not bad. Total cost of shaft making it myself was about fifteen dollars including joint, ferrule, and tip.

They are tubes full of structural foam

ideologist · Dec 15, 2018

Looking at these, they appear to be made for golf clubs

Wall thickness

Most on the market have wall thickness of about 1 mm and filled with wood or foam.

Mine are hollow and have a wall thickness of 1.5 mm

Non Revo shaft

Yes have dealt with them for awhile, cant get right taper for cues without 1000.00 die set up. Then you have to know how to fill it. Most don't come with a player friendly smooth as glass surface. Ive made quite a few for the guys that don't want the $500.00 Revo shaft....great sales pitch.

Here's a few shafts I have made using CF tubes. What to fill them with and also how to finish the outside is the key factor.The taper isn't as long (skinny) as the Cuetec or Revo but very playable.

First picture my CF shaft is on the left side and a revo is on the right (outside finish is identical).

Second picture a break shaft and 2 playing shafts one 29 and one 30 inch, break shaft 30 inch

Just bought the pool carbon fiber tube. Does anybody here know what material is best to fill the tube?

Non-expanding foam?
Low-expanding foam?

My question is......
How do get the foam on the lathe to turn it down so you can slide it into the CF Tube?

logical · Nov 7, 2019

Buying a random tapered tube that was not specifically engineered to be a pool cue shaft and trying to home brew it into one is not a high percentage proposition.

Carbon fiber is an ingredient in a composite material, not a defined substance like 316 stainless steel or nylon 66 plastic. Just like a "fiberglass boat" is really a plastic boat with fiberglass reinforcement in the plastic/resin...a "carbon fiber shaft" is a plastic tube reinforced with carbon fiber. In most cases it is filled and/or built around a non-structural form. What's important is what form and content percentage the carbon fiber amounts to. Is it long strands, woven mesh, chopped short strands, how wide are the ribbons, how many layers?...and on.

The other challenge is getting the joint and ferrule attached in a way that gives it the right feel and durability. If you think you can get this right the first time using a shaft of unknown composition ....well, I admire your optimism.

Its probably injected in a semi-liquid state and then expands and hardens. You don't turn it.
