Radial shafts not fitting well on non-predator cues

[maxeypad2007]

I have a Nitti and a REVO and have never had a problem. Maybe see if Predator will swap shafts for a new one?

I have multiple revos and this is the same situation with every single one of them unfortunately.

When I sent my Revo back to Seyberts to get it to fit my jacoby butt, this is exactly what they did. When I sent it, I was 100% convinced they would just run a tap through it and be done with it. When I talked to them on the phone, they told me they just added some shaft wax to the pin and took it slow screwing in and removing the shaft a little bit at a time. They warned me I might need to do the same due to difference in climate when the cue got back to me.

I just did his with a predator shaft, radial into a phenolic joint, used chap stick. I'm curious why this works, I wouldn't think phenolic has a whole lot of give to it.

it doesn't give, the chapstick just acts as a lube.

makes sense I guess, suppose it will tighten up as the chapstick wears off. Seems like running a tap through it would be a more permanent solution.

• you will have to do this many times over as the radial pin is designed to be a high friction thread anyway.

Threads to not work by having "friction" !
Threads work by creating tension--and the thing that tension is applied to is the thing that has the Friction !
Cue assembly Friction is between the face of the butt and face of the shaft.

Also, Threads do not create concentricity !
Concentricity is created by a pilot or tenon or register.

Threads absolutely do create concentricity. We've all had hundreds of non-piloted cues in our hands over the years. They all close the joint the same way each time.

Threads are a bunch of cones in effect. When there is a force on the cones, they center the whole assembly.

If this wasn't the case, every McDermott and Meucci ever made would be proud on the joint when assembled. And the side sticking out would be different each time it was screwed together.

Does your radial pin on your nitti have the same uniloc logo on it like the predator does? There is radial and uni loc radial from what I have read.

The Radial pins you buy from Uni-loc corp. Does not have a logo like you find on Predator cues.
There can be small variations on the pins, but no more than a thou in my experience. Radial pin works much better when you tap/screw into wood Vs. Phenolic imo..
