We are pool table mechanics. We do not use dollies to move your pool table. Modern day pool tables consist of 3 piece slate. Most pool table movers will not level your pool table to precision. Pool tables only play to the accuracy they were assembled to. When 3 piece slate pool tables are moved with dollies instead of dis-mantled properly the risk of shifting slate is a high probability. If your pool table does not have a name brand such as Connelly, Brunswick, Olhausen etc.. this ratio is higher.
