Diamond Professional 1 piece roll issue

Curious why they are not dead on when shipped.
They should be but any precision tool should be checked and re-calibrated when needed. Re calibration and certification is a huge industry. Luckily these machinist levels are pretty easy to calibrate.

I bought mine used and it was very close but I adjusted it a hair.
 
I would think a granite surface plate would be good for calibrating a level. Probably overkill though.
 
I have a similar roll on my GC4. Gonna have to support the frame I suppose. Balls rolled perfect after leveling for about 3-4 days.

Now after a about a week, the same rolls that were present initially are back. I'm sorta baffled by it. The corrections to the rest of the table are perfect, just the corners rolling out a bit long rail past the sides...doesn't roll everytime either...off a 1/4" left or right and it may stay true.

Thought I had it sorted out, lol. Now have new cloth on it so not sure what, if anything I can do to it. Got me scratching my head.

Just a thought, and not knowing what balls you use, but trying a different and maybe higher quality set of balls may be worth looking into.

I can definitely see a machinists level being slightly out of calibration even when new. They are so sensitive that a machinist level not at room temp may read inaccurately.
I check mine on my steel work benches, I just draw a marker outline around it to get it back in place when rotating 180 degrees but its easy tom do that on steel because you can just wipe your marks away, its probably not ideal to use this method on your pool table. :):)
 
Likely excessive amounts of glue. Possibly slate was not prepped properly. (removing any glue from the top edge of pockets and top of slate)
I can feel the glue. It’s slightly spongy .. just enough to stop/hang a ball. I’m willing to re-do the cloth again (3rd time) if the right mechanic comes around. Now I know what to look for. I’d prep it myself I could get the assembled top rail section off. If we learn by experience… I’m getting experience.

So, why is glue better than staples in the first place?

Diamond tables only use glue. There is no wood under the slate to staple onto. The mech should have looked and dealt with it. He knows better. Or should I say maybe he doesn’t. Maybe other table owners can benefit from this.
Diamond tables… only as good as the person putting it together. And I got no recourse from Diamond.
I should have bought a Cent or GC from
Mark Gregory… by the time I’m done here it would have been cheaper.

Good direction, let keep making improvements to the tables that you have no chance of getting installed correctly. I think all the manufacturers are guilty of it. My mechanic did a great job installing my gc4 but said the improvements, like the new leveling system just makes their job more difficult. Once I found out what that was I'd wished I waited for a 3 to be available. I like simple.
