A few months ago, I asked for input on a 22” x 18” cutting board that was warping. After a few attempts, I’ve sorta fixed this one, but now I have a request for another, and I want to get it right from the begining. I’m using 3/4” thick x 1 1/4” wide pieces, alternating maple and cherry. For the first one, I used no internal stiffeners (I’ll explain below) and Titebond II glue.
I’ve seen plans where the pieces were “threaded” onto two pieces of 1/2” or 3/4” dowels. This helps w/ alignment during glue-up, and supposedly helps prevent the board from warping. For my new board, I plan to use polyurethane (Gorilla) glue and, instead of wooden dowels, I’m considering steel rods or steel all-thread. These would be either 1/2” or 3/8”, and the end slats would have blind holes to cover the ends of the steel rods.
What do you think? Is there a possibility of rust, even though the rods will be encased within the board? If that’s a possibility, I can epoxy-paint the rods before assembly. This is sometimes done w/ rebar in certain concrete pads.
