OverviewUsed for beams, girders, crosspieces, and other relatively large timber components. It's a joint that involves notching two pieces of wood in a chin-hanging manner and inserting pegs of the same shape.
PrecautionsWhile it can be expected to have relatively good tensile strength, its lateral bending resistance is inferior. The length of the joint should be 3.5 times the width of the material, but sometimes it can be made as long as 3.5 times the dimension of the component.
