Dear Cobra, You know I don't like diamond's ball rebound off the cushion, and we see each other on every one of these threads. But, I'd like to comment on what you wrote here.
1) You mention here the positional importance of the body of the cushion with respect to the nose of the cushion. You can easily show that in a geometrically accurate drawing. Just like bradsh98 in this thread posted. (Assuming all of his cushion and rail profiles ARE correct). That is quantifiable. There could be a linear dimension behind the nose, in a chosen direction. Maybe that direction is parallel to the slate. Or maybe it is in some other direction deemed more appropriate. Or there could be an area dimension of the cushion behind the nose. The point is, you can quantify the "meat" behind the nose using drawings like the OP posted. Yet, you blast him and say "he knows nothing". Instead, why don't you work with him, and put your knowledge of "what plays the best" into a drawing that is quantifiable. A picture is worth 1000 words.
That's a lot of maybes buddy! And what happens when the drawing of the rails, the design per say, combined with the cushions don't turn out the way you imagined the table would play when you designed it to play???? Do you correct the drawing, or do you redesign the rail to play perfect with the set of cushions being used, test the playability, then if it's exactly what you want....THEN DRAW UP THE DESIGN....BECAUSE NOW IT'S PROVEN TO BE THE RIGHT DESIGN DRAWING!!!
2) You "rebuilt" Stans Diamond table TWICE!? That is another PRO player who had a problem with Diamond cushions. What was his problem with the original ones? Did they rot out? Or were they in good condition, but he did not like the play? Were his original ones red or blue (before you touched them).
Stan had a red label to begin with, so i rebuilt his rails to the blue label, he was overly joyed with how the table played, as was his friends and students. Month's later Stan talked to me on the phone about how his 14.1 game was on that same table and that he just couldnt seem to be able to run 100+ balls on it, and wondered if i had any ideas like a faster cloth or something. I responded with i didn't know he played 14.1 that much and that yes, i could make the table play differently for 14.1 so i came back you to his house, took the rails off, took the cushions off, redesigned the sub-rails then put new cushions on again, put the table back together, told him to call me after he's played on it a while to let me know what he thought then. Didn't take long, Stan called to tell me what ever i did to his rails made a big difference in playing 14.1....and so did one of his students, as there was a write up right here on AZ about how i could take a perfect playing table.....and make it play even better!!!
3) He did not like them AFTER you cobrasized them. How can that be? You claim on here for years your rails play the best and you never have a dissatisfied customer.
Stan wasn't unhappy with his table, you assume a lot!
4) More excuses for Diamond tables: he is a straight pool player, and not a 9 ball player. Therefore cushions need to be different. Come on, you can really say that with a straight face?!?!? Did Sigel and Varner play the best 9 ball, AND, straight pool, AND bank pool, AND one pocket, the world has ever seen, on Gold Crown tables with the SAME cushions for all the games?
Sigel and Varner also played on woven wool cloth, not Simonis, and played tournaments on GCs with STOCK 5" corner pockets!!!
5) You claim you and Mark are the only people on the planet who understand the importance of the "meat" of the cushion behind the nose. And that even Diamond and Brunswick do not. That might be, but it is not because other people are stupid, or "don't know what they are talking about", or, because they are "mechanical engineers". Its simply opportunity. Who else has the opportunity to try 10 different wood angles, 10 different cushions, etc. Only a manufacturer really can go that extent, or someone like you or Mark who its their passion.
Did Brunswick do all of that RD work 60 years ago? Who knows. Probably no one alive today. Unless there is a written record of that in the engineering books at Brunswick still around somewhere.
6. More excuses: from the past, you claimed diamond tables need polished balls to play their best. John Schmidt also on this forum said the same. While that might be true, why is that? Gold Crowns play fine with polished centennials, and also garbage dirty, scratched up, chinese balls.
7. Back to the GC, no one complains about how the rails bounce, UNLESS the cushion went to shit. The GC cushions have been fine for 20 years now, and have a very long life expectancy. We all know for a few years, super speed cushions were garbage, while Brunswick was looking for a new supplier for the cushions. Maybe that is why Diamond went with Artemis. But, in 20 or 30 years or however long Diamond has been making tables, the rail bounce has consistently been the number one complaint. By bangers like me. And by pros, like Archer, Owen, and by everyone in between. Players don't complain about GC bounce. So, after all of these years, why in the world does Diamond not simply copy 100% the wood geometry of the GC, and go to the same company (even if Chinese) and buy the exact same super speed cushion, and simply put their logo on the cushion and not Brunswick's. If the cushion company is Chinese, I promise you, they will have absolutely no problem doing that.
This isn't rocket science!
Freaking merry go round.
