I have to build one edge grain and one long grain walnut cutting board.

The board is a rectangle 14×24” with a radius edges. The height/thickness 2” The glue ups are made from a 6/4 material. The glue up is pretty thick (at least 2”) I will be using Titebond 3.

I was wondering if I should put biscuits or dominino’s when I glue it. Is that going to help to keep the joints stronger? Or should I just plane it once it’s glued and add a groove on each sides with a cross grain wood in it?

Not sure if I made my self clear enough.

Are you saying you plan on making the cutting board 2” thick? I ask because if so that will make a cutting board that will be a little too heavy in my opinion. 1-1/4” or so is plenty thick enough for a cutting board.

To your question, are you talking about the second drawing? If I understand correctly you want to put a couple of strips across the cutting board 90° to the 24” long dimension. That would be an edge grain to end grain joint. A few biscuits or dominos wouldn’t hurt. Across a 14” span just gluing it might work, but it better to have a joint that’s too strong that not strong enough.

If you do a good job of preparing the stock (clean, flat faces glued to clean, flat faces) then there is no need for biscuits or Dominos.

I do these all the time. TBIII is stronger than lignin—-the natural “glue” that holds the wood fibers together in the board. With a well-prepared long-grain joint, the glue joint will be stronger than the other parts of the board. Skip the biscuits/Dominoes.

Do NOT put cross-grain wood into the mix. That is a recipe for disaster. Use dry, stable stock and your cutting board will be stable.

Don’t know what you mean by ”one edge grain and one long grain” Maybe one edge grain, one flat grain? Or one end grain??

Thanks for your answers.

The board will be nested in a platter. It’s not going to be use for cutting but mostly for display. I think I will build it without any biscuits or Dominoes.
