I would like to make a bread board, about 2 feet by 3 feet.
I donít have a joiner / planer to glue pieces together and then plane them
Has anyone made one? Any ideas?
Ok, there's a bunch of stuff here.
Firstly, before the advent of international trade on a grand scale, local craftsmen used to sell wooden pastry boards. I have one. If you keep it well floured, it works just as well as marble, especially with vinegar-based pie pastry.
Next, if your pieces are of like thickness and your joint edges are clean, it is possible to do a seamless glue up. You use a thing called a caul. Now, before you go running off to the dictionary to find it, I'll give you the definition, to wit: "A curved batten, usually used in pairs for applying even pressure across wide workpieces" (Wikipedia)
I usually just grab two pieces of warped spruce 2x4, convex curves toward each other with the workpiece between them, and clamp the ends together using "C" clamps. The spruce is particularly warpy and springy that allows it to be a good material for this. What it does is press all the boards to the same plane so the joints are all even. Use cauls in conjunction with bar clamps of some sort that will squeeze inward at the same time. It might help to cover the cauls with wax paper to keep the glue squeeze-out from gluing the workpieces to the cauls.
However, I must caution you. A chopping board (with the knife cutting into the end-grain of the wood which helps preserve the sharpness of the knife) is entirely different from an pastry board that uses the side grain to prevent contamination of the surface. Because of this, wash the surface of the pastry board quickly and dry thoroughly. I would also suggest that you create a containing tray into your design. If the board were in a tray with a 1" space all around, it would help reduce the "spread" of flour while rolling out pastry.
Rather than sand the surface of the pastry board, use a scraper to "finish" the surface. This will slice through the cells of the wood and leave a minimum of scratches and pits for contaminants. My board is unfinished maple.
