Thunderdome Swamp Board
After being introduced to Thunderdome at CaptainCon 2015, I knew we needed a board for our local store. I set upon it immediately to get it done before our Reckoning event.
The boards we had seen were 36″ diameter circles and designed for up to 8 players. In order to provide a nice wood border around the outside I decided to go with an octagon. The octagon I built has a maximum diameter of 36″ which means the flat edges are 33″ apart. Each interior edge is 13 3/4″, with 22.5-degree angles cut on each end to form a regular octagon. The bottom is made of hardboard and the edges are strips of a 2×4 I ripped down to 3/8″. This keeps the board lightweight but sturdy. I routed grooves into each edge piece that housed the hardboard. Wood glue in the grooves and the angled edges holds the board together. For some additional strength I also put two nails in each corner.
