Some years ago, I saw an advert in a catalogue for a 3 Player Chess Set. I thought it looked really nice, but I didn't want to spend the money to buy one. Instead, I came home and made my own. It looks a little like this:
I didn't bother with the labels on the edge, and the pieces don't look exactly like that, but otherwise, it's a pretty good comparison. However, the disadvantage to making my own board was that I didn't have the instructions for it. I tried a few times to get people to work out the details with me, but it never really quite happened.
