yesturday before league i spent 10 minutes leveling a bar table....

i got it alot better than it was, and i only had crappy bar balls to roll

my question is this the table rolls to the inside down both rails/ both ways about a half inch or sometimes more like an inch.

is this because the frame is sagging in the middle??

do you shim the slate somehow for a quick fix... whats the right way to fix this?

sorry if there are a million threads on this already.

You got it. Slate is sagging in the middle. Very common on those tables. You can shim a bit in the center on the cross beams to help, but you can only do so much before you're picking the slate up and the rails won't be at the right height or will be tough to start the bolts.
 
I would say more than half of valley tables have center sag that cant be shimmed back to level. One thing alot of people dont realize is that magnetic cue balls aren't true. If your testing the table level by rolling a ball, make sure its an object ball.
 
You can do a fair amount of shimming on them, but you may end up having to shave a 1/16 th to a 32nd off the bottom side of the rail to allow for the amount of shim that is required. This can be done with a table saw and a good fence,they will require recovering to do so...!!!

QBall,
If you shave the bottom of the rail you are bringing the nose height closer to the slate. I understand you are not talking about cutting alot of the rail away but most coin-ops already have issues with incorrect nose heights. You run the risk of jumping balls off the cushion.
 
Agreed. I wouldn't go cutting anything off the rail. It's the wrong fix to the problem. You shouldn't fix sagged slate by making your rail height incorrect also. You should adress the problem with the slate.
 
The proper way do adress the problem is to scrape the bottom of the slate, however the sag has already occoured, so now you have got to bring the center of the slate back up to level which will require shimming. Your not changing rail height by shaving the bottom of the rails all you are doing is allowing room to shim, the rails will still bolt on the same. If you have ever dealt with penguin rails they are all shaved short to allow for glue build up and shimming...!!!

pull the slate, and correct or replace the cross-members to account for the sag.

You still have the issue of the rails bolting on. In theory a true fix is to add the middle legs and remove the sag from the bottom up.
