Standardised Rail Response Test - is there one yet ?

[realkingcobra]

I dont suppose you know how fast (in mph) you were hitting the CB for both those scenarios do you ?

Firm hit = ?? MPH ?

Great to read all ur other comments - thanx.
Cheers.

No matter how hard you hit the cue ball, the cushions are going to have a certain % of speed loss every time the cue ball comes into contact with the cushions, so as hard as you can while keeping the cue ball on the playing surface. That don't mean you'll get 5 rails, or even 4 1/2. As Mark pointed out, it has a lot to do with how the sub-rails are matched up with the cushions, but also what kind of cushions. Very soft cushions are not going to respond as well as cushions a little harder.

Table

The test was a trick shot on and Olhausen table....we're they would place and 100 dollar bill under the 9th rail. You needed to get as close to or on the bill in a sudden death play off.
The best way to play the shot if your shooting the cue ball into the right side long rail first....you would need to help the cue ball get around the table using low left hand English on the cue ball.
The draw shot on the cue ball will allow you to hit the cue ball harder and not make the cue ball jump off the short rail..

This ttest will tell you if the cushions are setting properly on the sub rails.....
The thickness of the sub rails....the bolt system.....brand of cushions.....don't mean your cushions won't get 9 rails.....or track the table properly.

The sub rail where the cushions glue....need to be calibrated according to the brand of cushion your wanting to use on your table.

The sub rail thickness and bevel are different on Diamond....GC...Olhausen....tables and on and on with all tables......that's why not everyone uses the same cushions.

I believe that a table should get 9 rails around.....that shows the tables rails are tracking correctly.....now I don't believe the table should get 5 rails the length of the table.....I believe the table should get 4.5 on the length with a firm hit.

I get 4.5 with Brunswick super speed.......and 5 with Artemis cushions.....with I think play a little fast to me for pool. Both are 55 cushions.
Rarely do I use any other cushions for my rail work.

I'm still trying different things with the Artemis cushion.....I want them to play the same speed as the Brunswick super speed. (5 years and still trying....LMAO)

Most of that just went over the pool players heads.. Marks rail work is a bit advanced and far to hard for most readers to grasp.
Hats off to you mark for the effort put in to solving that tricky limitless box you refer to.

i seen glen, and i'm positive you can do it, have the CB stop on the $100 bill. it lays natural. IMO a table that-that shot lays good on is about right. not to bouncy, or a table that just rolls long for no reason-that really irritates me.


Mark, i need to talk to you about a personal thing, I'm shot today. i'm gonna call you tomaro from a Vegad number you dont have in your phone-so when you see a 702 area code its me:thumbup: nothing to sweat, over hell i been meaning to call you about it for a few months. hope your good man!!!!!

Fatboy, did you sell your Diamond, or put it in storage?

Eric.... always nice to hear from you....my line is always open to you....but you knew that buddy.
Things are going well....have a lot of centennials and anniversary tables I'm restoring.
Brother...it's a lot of work.....and I'm never happy till I do things 5 times...LMAO

Talk with ya soon.

so as hard as you can while keeping the cue ball on the playing surface.

ok - so the BCA pro spec says :-
______________________________________________________________________
8. Cushion Rubber
Table cushions should influence the speed of the table such that with placement of a ball on the head spot, shooting through the foot spot, using center ball english, with a level cue and **firm stroke**, the ball must travel a minimum of 4 to 4 ½ lengths of the table without jumping.
______________________________________________________________________

This translates to "A minimum of 4 to 4.5 lengths when **hitting the cueball as hard as u can without causing the cueball to jump.** " ?

Anything less than this = el crappo dead rails / time for new cushion rubbers ???

Cheers.

Ahh - what a difference a tried & tested method makes ! (RKC's X to O bank round the table test)

8 rails hitting from X to O (running english) is the most I can get on my table. (cue ball finishes at "S" instead of "T')

Its good that just slamming it hard with centre ball doesnt work - ball jumps off 1st and/or 2nd rail quite a bit.

This looks like an excellent method to test rail bounce at decent speeds.

So - 9 rails is good or bare minimum ?

Who's got a Diamond Pro or Gold Crown V with 860 on it ? how many rails u get with this X to O bank round test ?

Thanx
Cheers.

I performed this test on my table 10 times. I consistently got 8 rails with the cue ball terminating 1/2 to 3/4 of the way to the 9th rail. Not bad for an old AMF (T Rails) with Artemis and Simonis 860. Steve (teablemechanic) set up the rails with subrail extensions (4" pockets). When I change the cloth to 860HR Tournament Blue, I think I will stretch 9 rails out of it.

Thanx very much bro' - great to read ur results & table specs.

Nice table - tight pockets !

Cheers.
