I covered 3 bar tables a couple of months ago and have been running a weekly tournament on them and I level the tables every week and I was just checking them in the center and keep having problems so i checked them in other spots and found out the slate is warped i wanted to know if anyone has flipped bar table slate over and if it would hurt anything i know some slate has grooves on one side from the honing of the slate I would love to have other techs input on this thank you
