Pocket angles

Hi,

Looking for some help please.

I have a GC3 that I've bought some new cushion rubbers for. I'm thinking about cutting the pocket angles to the same as a Diamond table - would someone be able to tell me what the angles for corner and middle pockets are on Diamonds please?

Thanks in advance.

141 corners, 102 sides. Your down angle will be different than a Diamond because the shelf is deeper. Just follow the factory down angle. GOOD LUCK and post pics/ keep us updated on your progress!

Are you planning on extending the subrails? No point in having Diamond geometry on 5"+ pockets.

Shouldn't the angles on the cushions match the wood on the end of the rails at the pocket openings??

Yes. Hopefully he's cutting the subrail and not just the rubber. To me, it makes no sense to do this unless you are extending the subrail.

What is a ‘down angle’?

The angle from the top of the rail to where the bottom of the rail meets the playing surface.

I thought the down angle was the amount of downward slope of the top surface of a cushion. The cushion's upper surface slopes slightly down to the nose of the cushion. This is what caused red-label Diamonds to bank short, the upper side of the rail was angled down too steep causing ball to kinda get pinched and go short. They changed the sub-rail angle on the blue-label to address this.

No sir. The red arrow in the pic below points out the down angle of the pocket opening.

I'm not a mechanic but I'm pretty sure what you are referring to is the subrail bevel. On my GC1, I think my mechanic beveled the subrail at 23 degrees to accept modern K55 profile cushions. Whatever angle was used, the cushion height is perfect and the playing surface cushion point to cushion point is 100" x 50".
 
In regards to pocket angles, you can refer to it however you want: downward angle, down draft angle, vertical angle.. It all means the same. I use the following terms for pocket angles: 'lead-in angle' and 'downward angle'.

When referring to cushion angle, it's generally referred to as the 'sub-rail angle' or 'sub-rail face angle'.

You would be incorrect. The cushion “down angle” as you say is actually the cushion “profile”. The down angle is the angle of the downward slop of pocket facing.

Right! Has nothing to do with down angle. Isn’t that exactly the same thing I said?

Not really. From your post above. "The cushion 'down angle' as you say is actually the cushion 'profile'."
