Modified 3/8x10 pin, What are your opinions thoughts?

Sheldon said:
The modified pin is better than the standard, since with advanced installation procedures, it's much more precise.
Some are satisfied with using taps, even unpiloted ones, but it doesn't take much to take it to another level, so why not?
The flat bottomed pins and radials require more precision, and if someone doesn't have the equipment, they are better off not using them, since an improper install is less forgiving than it is with a standard thread.

Sheldon, :eek::deadhorse:, :rolleyes:, :thumbup:
 
Rick as a point of clarification I believe the pin Bryan was referring to was the dpk pin that went into southwest cues rather than omega...
 
Anyone wanna tell this story of the SW brass choice? I have not heard that one.

Zud -- G-10 is a material, not a size.

Joint pins can be made from many different materials. Examples: stainless steel, brass, aluminum, titanium, G-10.

3/8 x 10 is a size -- 3/8" major diameter and 10 threads per inch.

Joint pins can be made in many different sizes. Examples: 3/8 x 10, 3/8 x 11, 3/8 x 14, 5/16 x 14, 5/16 x 18.

And, yes, I believe quite a few cue makers are using the 3/8 x 10 modified pin, also called 3/8 x 10 flat-bottom pin.

I have an old cane cue, that I believe has a brass 3/8 x 11 pin that screws into butt.
Anyone know where I can find a replacement brass pin? I would be grateful. PM me!
 
I have had both, don't see or feel any difference. Play the same to me. Some after market shafts don't fit as well on 3/8-10 modified pins. Sometimes the shaft has to be bored out a little. ( a bother ) . For that reason I stay away from them, sticking with standard 3/8-10 pins.
 
" Can a modified 3/8 x 10 shaft fit on a standard 3/8 x 10 pin and vice-versa?"

Yes you can in most cases.

Unfortunately this is still confusing to me.

So a modified 3/8 x 10 shaft will sometimes fit a standard 3/8 x 10 pin? How can one tell when?

Now what 3/8 x 10 pins are used in after market shafts like Predator and OB? Modified or standard.?

And how con I be sure what is on my Olney or Sugartree cues which claim to have 3/8 x 10 pins?

Thanks in advance for any help.

The joint screws on Mr. Olney and Mr. Crisp are very different from one another. Mr. Olney joint screw requires a much smaller hole. Where Mr. Crisp uses a modified screw. So, if you have a standard shaft with a 5/16 hole from someone else, it will (should) fit both. On Mr. Olneys it will wiggle while your tightening it. More snug on Mr. Crisp cues. The Olney shaft will not fit the modified screw unless you modify the hole.
Hope this helps.
 
Michael,

Thanks so much for that information! Very helpful.

And if I can ask you one last question:

So aftermarket shafts like Predator or Ob would fit better on a Sugartree verses an Olney.

Hi Roberto
Yes. But the Predator may need to have a tap run into it. It's made more for the standard 3/8x10 than the modified. Just might not swearing to it. OB uses a modified joint screw on they're cues. So thier shafts should fit the other modified screws without chasing with a tap.
Happy Holidays
 
the 3/8-10 modified pin I designed about 10 years ago. the reason behind it was that the
standard 3/8 10 pin had a minor dia, of .231 to .254 and most cue makers were boring anywhere from .280 to .312 so the the surface transfer from pin to the shaft was very small around .030 per side so with pins like SW and radial where the surface contact was almost 90 to 100 percent so I designed a diameter that would not get confused with the 3/8-11 pin and I put a radius on the pilot to also give a different look .the surface transfer to me is a lot better at 90 percent so 10 years later it is doing very well I did not know of anyone els that did that pin that way I think chudy was the only one and his minor was .312 as for other shafts the can work with the modified you just have to have a.308 minor . any 3/8-10 taps will work fine the pitch is the same so standard taps work fine
but like mike said it is all personal preference but the modified to me is and over all better fit and that is what everybody is looking for I would think

Since there are so many bastardized 3/8 10 already, I hope the ball screw and 3/8 11 do not get bastardized.
Can we stick to 5/16 minor on all 3/11 from hereon???
Why do smaller minor 3/8 11 need to get made ???

Heaven forbid someone buys 3/8 11 screws on ebay too.
Those are even more f'd up.
