New Revo Shaft won’t fit Predator LE4 butt.

Not a typing error. The original 3/8x10 joint screws are rolled thread with a .281 minor. Just so happen to work gread 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
I'm missing something here in your communication. You stated you use a .281 tap but your bore the hole to .312 The tap is smaller than your bore

The minor is but not the tap.
I always say,
I don't know everything but I'm trying to
Have a nice day!
 
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
I know minor and major diameters, but please explain what you are telling us above. Sure the 5/16 reamer aids in opening up the phenolic tell us what you are doing with this special tap .281 Maybe your wording was incorrect No one uses a tap the same diameter as the minor of the pin, nor will a .281 tap do anything in a .312 hole
Maybe you meant a .281 hole for your 3/8-10 tap that would work, then ream it with the 5/16
I'm not trying to argue with anyone, i'm trying to learn something here. The tip about the blo and sealer was good +

Maybe you could learn to communicate better i think you left out quite a bit . Your numbers don't work from this end. Maybe you are having a senior moment lmao
Go back and read what you posted your special. 281 tap made by Widell you use for a 3/8-10 pin install. Still wondering how you could thread a 3/8-10 into a .281 thread. Maybe you meant the drill bit you bored the hole for the 3/8-10 tap was .281 that would work then you could use the 5/16 reamer to make it fit the modified pin.

Perfect
We agree
You don't understand
 
Got it
It's amazing how much you NON CUEMAKERS with phone names bug me.
Wish that would change

Old 3/8x10 joint screws have a minor of .281
The tap I had made will tap a hole of .281 without tearing the threads.
So I call it a .281x10 tap
Simple eneogh for ya

That clears it up the tap is not really .281 x 10 just what you named it

What Mr. Webb is saying that what we commonly reffer to as 3/8-10, like what McDermott uses, really has a much smaller minor and most regular taps you can buy tends to tear the hole at that minor. With the regular taps sold by places like Atlas, it's hard to get nice looking threads before you go .288" - .290" wich gives a fit with a little slop.
