What is the name of (if there is one) and what causes the "ridge" at the spot where the bottom of the ferrule meets the shaft. Hope thats a good description.

The OD of the ferrule is slightly larger than the OD of the shaft.

Its almost like the shaft shrunk a bit ?
 
That's exactly what has happened...if it's excessive it probably is from a shaft that has been turned down to fast...sometimes climatic changes will cause this to a degree...

Some ferrules (called fiber), are made of a pressed paper material. If they get damp, they will swell. It can also be caused by the shaft wood shrinking, due to dry winter conditions...JER
 
Thanks!

This happened to two shafts from the same cue. Both shafts are laminated, the type of laminated shaft made from the very thin strips - not pie shaped like Predators.

Based on what you guys say-it sounds more like the ferrule expanding a bit?

Thanks Again

I've had a problem with this latley but with only one ferrule material. It seems that the ferrule is expanding. Its an easy fix but it shouldn't be that way. I think am going to switch ferrule types.
 
sanding and shrinkage

It sounds like either the two materials sand at different rates or the shaft is shrinking. Sometimes improper sanding will heat up the ferrule and shaft, making it expand (depending on what material you are sanding), then when they cool down, one will contract more than the other. Good luck, Kent

Tap, Tap, Tap, Also true of some othe materials as well!
 
I see the same problem on some of my ferule replacements. It usually takes about 4 days for that swelling to show up. Any hints would be great. I usually use a rather soft ferule that is threaded and capped from Porper. It is kind of embarrassing when the customer points it out to you a couple weeks after you have thought it was perfect.

The Porper ferrule is a molded polymer blend so I don't think the it would swell but I haven't seen too many come back for any reason. I am having a problem with a certain linen based ferrule. Like Bob said, it shows up after a couple of days. The shaft diameter measures correctly but the ferrule has popped. Its not every one but enough to annoy me.

I have had the problem you guys are spaeking of also. The linen based ferrules espically. The Porper ferrules don't see, to do this. I do a lot of resizing work on Predator shafts that have ferrules that swell, the old ones, I haven't seen the second generation do this yet.
 
Saber-T Ferrules OK

I had problems with ferrules until I started using the Saber-T Ferrule material. It is a little pricey but considering that I don't have any problems with it either during installation or after the fact it rapidly becomes the least expensive of all the other materials available today.

Stop messing arround trying to save a few pennies and get some Saber-T Ferrules. You will be glad you did.

Good Cuemaking,

I totally agree. Saber-T is one of the best synthetic ferrules I have ever seen. It is also pretty easy to work with.

Elforyn is along the same lines. Easy to work with, looks/plays like ivory, and it glows under a black light.

Don't think you'd go wrong with either. What's a buck or two per inch when you are building a cue?
 
Physical Characteristics of Linen based Phenolics

Hey guys,

It is not possible for a phenolic material to expand or contract without completely falling apart. After the phenolic resin has been baked, it is SET in place and can only be machined to size. This is where the term "thermoset" plastic comes from. In other words, set with heat.

Do you mean fiber ferrules? Vulcanized fiber and similar materials WILL take on moisture.
