Melissa, my daughter, sent me a suggestion for a game for the grandchildren for their visit this summer.  The plans for the game came from HomeDepot. There were some challenges with the plans, namely the sideboards needed to be cut to 1-½ inches so the disks would fit in the outer slides.  Using a 5-inch hole saw on an electric drill is near impossible, so I cut the out with a jigsaw only to learn that the actually disks need to be no larger than 4-¾ inches.  Fortunately were were headed back to Richmond for the weekend so I deducted the size using a bandsaw and a home made circle jig.
