I have a way to help prevent that. It’s called “bread board ends”, which are boards on the end of the laminated piece that are attached with tongue & groove joinery. These end pieces run perpendicular to the rest of the board. The cross-grain orientation help ensure the board will stay flat, even though the board is as thin as 3/4″.
This kind of board is often used as a pastry board (hence the name); a variation of the pastry board includes a “counter hook” that grabs the edge of the counter. This way, the board doesn’t creep away from you as you roll out the dough. But I digress.
Bread board ends are also a feature of well-made “in counter boards” which are a feature in many kitchens. These boards fit into a slot in a cabinet, and slide out when a cutting surface – or just more counter space – is required.
Due to a change in the building code, these boards are now difficult to find in LA County. Replacing older boards can be very difficult – and essential.
These are the latest 4 boards out of the shop with bread board ends. 3 are commissioned pieces, and the 4th is the first ever cutting board with bread board ends I’ve made to sell in the booth.
