This joint connects two pieces of wood that cross each other, usually at a right angle. The carpenter cuts a notch equal to half the material's thickness into both members, allowing them to interlock flush with each other. It provides excellent resistance to twisting in internal frames and grid structures.
Heard on the job
Lay out the cross-halving joints carefully so the grid sits perfectly flat on the bench.
