I do not own a pool table.
A miniature pool table would be considered a toy, not a pool table. Depending upon the size, it could be made of plastic or wood. To choose a size, determine what size you can purchase the balls needed for the table. A lathe will be needed to make the pool cues. The rest of the table can easily be constructed of wood or plastic, and covered in cheap fabric store felt. There are plans available online for pool table construction. These can be used and scaled down to match the size of the pool balls that have been selected. The scale will be determined by using the same ratio for ball size to rail height and pocket openings as is used on the full size table.

A drained swimming pool will be more dangerous to anyone who could fall into the pit. The pool will need fencing around it that is sturdy and anti-tamper proof. What are your plans for rain water when it fills during a storm? What are your plans for when you have a lot of rain and the water table surrounding the pool rises enough to make the pool float out of the ground????
