And this is in rec.crafts.woodturning for what reason? Pegs might have something to do with this group, the boards themselves would be a bit tricky to do on a turned object (while that might be cute, it would be less cute for playing on, I think). Anyway...
How much would you like to pay? What sizes would you like? Any other specifics ( normal layout, "racetrack", weird squggly versions...).
As a long-time cribbage player, it's fairly simple to draw up a board template, even a 3-player one, but I don't work for free.
