Portland Pool Table Service is here to make your pool table play it's best. First we help you select the best table location if you haven't done so. After agreeing to the best location for play, we frame level the Pool Table leaving the highest leg firmly on the ground and raising the others to match. Next, each slate is individually raised and brought level with the other two slate using a Starret machinists level for unsurpassed level playing field. Shims are used in up-to eight different locations per slate. This whole procedure takes 1.5 hrs to 2.5 hours - just for leveling. Each piece of slate is shimmed in up-to eight different locations per slate if needed.
