New Revo Shaft won’t fit Predator LE4 butt.

So I have a predator LE4 butt that I bought in 2012. I got a brand new 30 inch Revo radial shaft for it. The shaft does not screw on at all. It gets on the first two threads and stops. Maybe 25% of the way down. My friend has a predator cue that he bought last year brand new and my shaft screws onto to that butt perfectly. I’m going to call predator in the morning, but did the things change over the years or do I have a defective shaft?

Sounds like this is a Radial pinned cue?
My guess is that your Radial pin is just out of spec enough that it's tight and you need to have a cuemaker run a tap through the shaft.

Yes it’s radial. And both products are predator so I’m surprised that it didn’t fit.

It's rare, but it does happen, it doesn't take much. Have you tried a little beeswax on the pin? If that doesn't work you need to take it to a cuemaker.
 
Kim got it right.... the phenolic threads have no give to them, and the older radial pins are sometimes slightly fatter. You'll need someone to re-tap the threads to loosen them up.

I wonder if that will void the warranty though ?? I bought it legit so I’m wondering if I should send it back

You won't even be able to see that work has been done. Don't sweat it. Try with wax first and if that fails take it to your local cuemaker.
 
When it comes to the radial or ball screw,
Whatever,
Use the 5/16's reamer. It really helps. It's on the installation guide from Uni loc Corp.
Wood is forgiving so the undersized tap gets you by.
Phenolics, juma, etc etc
Ream it!

So are we saying the pin has a .308 minor yet in phenolic we need .312 to make the phenolic accept the .308 minor ?

WE,,,,, AIN'T saying SHIT lmao!

I'm saying a reamer gives a helping hand in radial threads.
Btw
I use the reamer in wood too.

PROCEDURE FOR RADIAL® PIN SHAFT INSTALLATION
1. CENTER DRILL TO A 5/16 DIAMETER
2. DRILL .312 DIAMETER 2.300
3. TAP WITH RADIAL® TAP 2.00 DEEP

Mike is not incorrect to use a reamer.

Are you using the same size reamer in wood for the radial pin as in phenolic? The radial pin minor is .308. so wouldn't it be the same protocol as for a 3/8-10 modified pin install .308 in wood and .312 in phenolic
I use reamers on everything i do

I use a 5/16" reamer
For 3/8x10 modified, i use a tap I had Widell make for the regular 3/8x10
It's a .281x10.
Works perfect for the modified in a 5/16" hole. I also use a sealer after tapped then tap it again when dried.

BLO with bullseye sanding sealer. 5 to 1 mix

Is that a typo, how does .281 even touch the sides of a .312 bore

Not a typing error. The original 3/8x10 joint screws are rolled thread with a .281 minor. Just so happens to work great for the modified with a 5/16" hole.
Go figure!

If you have a shaft with radial threads, and tap it 3/8x10,
Why can you thread it on to either screw.
Beats the snot out of me, but it does
