I have a pool hall full of these tables. I'm having a hard time fine tuning the level because of the undersized frame. When pounding in the wedge the frame block will move down. I thought about using shims instead of wedges but I don't think that will solve the problem. I looking for a way to improve the frame that will only cost the house a couple hundred bucks and will give the frame the stability to hold a good level. Any ideas? here a pict.
