Please also find step by step pictures for installation of the ball return pool table below;
The legs of the pool table don’t have threads, they are attached from inside to outside within the box frame. The part that is holding them together is the square box frame (as shown in the instructions FIG 3) If the cushions are not perfectly fit to the pre drilled holes on the pool table top, you can easily use any nail (no longer than 50mm) to drill the hole yourself. The outcome is same.
The images below differ from the instructions provided, however both work depending on which you prefer to follow.
