MR 9 Ball Pocket Specs US Open 2024

Just curious here but why do people get so worked-up over pocket sizes? Every time i watch a match that has a chat it seems that all the railbirds can talk about is pocket size. Is pocket size gonna stop someone from entering a big event? Hell no so why sweat it? Don't get the obsession with this.
 
really don't know what subrails or facings are? play pool?
Just never heard the term sub rail. Helped cover several tables and the wood part were always the rails. The rubber only was the cushions. Sub is probably the wrong prefix. The separate facings I always called shims. Those tables are long gone But not all had those facings.

I honestly agree with you for the most part. Some of the terms used are a little misguiding.

Well I think the bulk of it is just self proclaimed purists searching for something else to complain about in regards to the "MR tinkering that's ruining the game".

Pocket 'size' is just an easy measurement/topic that the minority can fixate on. I don't doubt for a moment that a overwhelming portion of that minority has no clue as to the finer details of pocket specs that can actually make a 'tighter' pocket play easier.
 
Just never heard the term sub rail.
Not much reason for you to have heard it if you're not a table mechanic.

A subrail on a pool table refers to the inner structural component of the rail system, which supports the cushions (bumpers) where the balls rebound. The subrails are located beneath the outer rails (the parts you see and place your hands on) and are essential for the overall performance and playability of the table.

Here's a detailed explanation of the components related to subrails:

  1. Cushions: These are the rubber parts attached to the subrails, providing the bounce for the billiard balls. The quality and condition of the cushions significantly affect the gameplay.
  2. Outer Rails: The visible wooden parts on the perimeter of the table, often covered with a finish or veneer. They provide the aesthetic look and a place to rest your hand while taking shots.
  3. Subrails: The structural parts beneath the cushions and outer rails. They are usually made of wood and are essential for securely mounting the cushions and ensuring consistent rebounds.
The construction and alignment of the subrails are crucial for maintaining the accuracy and consistency of ball rebounds. If subrails are poorly constructed or aligned, it can lead to uneven or dead spots on the table, affecting gameplay.
 
I'm not well versed on table mechanics and measurements. I'm familiar with the playability of 5" vs. 4.5" vs. 4.25" vs. 4.125" pockets firsthand from playing on 7' and 9' tables of each. But I'm not familiar with how tables are built.

So I'm asking to understand. Does that mean...?
  1. The table rails are designed to have 4 5/8" corner pocket openings before any facings are applied?
  2. These tables would normally have had two 1/4" facings, making the final pocket width 4 1/8"?
  3. But MR used two thicker 5/16" facings instead, shaving off that extra 1/8", making the final pocket width 4"?
Or am I misunderstanding the starting rail length, standard vs. non-standard facing widths available, and forgetting to account the width of the cloth?

If you want to be exact, you also have to calculate the angle of the facings. On a corner pocket at 142 degrees a .25" facing would measure .406".

I think that will make the table play kind of easy, mine are 3/8th and everything falls in, even after some wear on the cloth. New cloth with those facings will play pretty soft I think.
That's actually the problem. Thick facings, or "double/triple shimmed" as some like to coin it. Make the facings too soft the OB tends to bounce back and forth and not directed into the throat of the pocket.

I’m following the principle. What is the story in terms of how pocket sizes are determined for an event like US Open? Are they getting rails of variable sizes and then using a standard facing? Or are they getting rails of a standard size and getting an abnormal facing? What facing sizes are they likely using to make 4.5, 4.25, 4.125 or 4” pockets? Well, it sounds like 5/16” facings for 4” pockets. But I’m just uncertain on what the common components are to make common dimensions.

Not my experience. May happen on a deep shelved table but on a gold crown at 4.5, they play like buckets with 3/8 facings, rare to have one rattle.

By the way, I don't think the facing that thick could be soft enough. In the room I play most at they have standard gc pockets, close to 5". They play tougher than my 4.5 gc at home in a lot of ways.

MR was the one making that decision.
I just can't wait till it's standardized for all, including the qualifiers down the road.
Like Snooker, who, when and how did they get final specs for their game.
 
Personally i still don't think its a big deal. Good players adjust so small target-size variances are just part of playing. I seriously doubt that a true 'standardized pro pocket' ever comes to fruition.
