My daughter came home across the New Year holiday and stayed this past week. Prior to her visit she asked about making a game board with Chinese checkers on one side and the marble aggravation game on the other with a place to store the marbles and dice. After looking at a lot of designs on the internet and developing cad layouts for eh two game hole patterns, I designed a two sided game board with an internal marble storage area. We built this together this past week. I did most of the woodworking and she did the painting and finishing. She drill most of the marble holes. My drill press didn't have enough throat depth to reach the interior holes so I had to devise a drill stop for the countersink bit we were using that would exactly match the depth of the outside holes on the remaining interior holes. The door on one side opens to allow you to get out or put back the marbles. It is held closed with two embedded rare earth magnets. It was a fun project. If you plan to build one of these purchase your marbles first. DAMHIKT.
