I do not have detail instructions on how this was done. But I used the following site as the bases of the project. Quite cheap due to the use of dimensional lumber versus furniture grade. http://www.hgtv.com/design/rooms/living-and-dining-rooms/diy... I used a 1/2" sheet of plywood for the game top with an underlay of felt with a Blue suede cloth on top. We could have gone with better materials for the playing surface but we keep this project on a budget.
The top was left removable with strips of wood to hold the boards together and in an order to keep the table from shifting when placed.
