Re: Inlaying large wood pieces
Mark
Ive made and played a few times with these Corn Hole board games at the cottage.
I would not be worried about the inlayed barrel staves being Dead flat with the plywood surround? I don't think the curvature of the staves is going to interfere with the playability of the game at all. If you finish the entire top, the bean bags will still be able to slide into the hole and/or bounce off the top just as easily.
Obviously your intention is to bring your pals love of whiskey into the design of the boards so i’d go for it trying to keep the top of the stave assembly as level with the plywood surround as possible. But I wouldnt obsess.
For wood movement you could rabbet the underside of the Left and Right edge of assembled stave triangle, and Top edge of plywood V where the stave will meet allowing for maybe 1/8 x 3/16 expansion and contraction.
I think your buddy will care more about having the barrel staves incorporated into the Game boards vs whether they’re dead flat . Good Luck with the Project!
