If I were to do this again, I would go for a thinner wood. I actually sampled a bunch of exotic woods to make the tiles out of, and would absolutely recommend that as well. I gave this board to my brother for his birthday, and as soon as I can carve out some time, plan to make another!
Shandy, the designer has done an amazing job of chronicling his project at boardcrafting.com. I highly recommend checking it out. You can buy a custom board there, or the files to make your own! I made this one at Techshop.
