The usual method of scarfing bond and wallplates is by cutting about three-fifths through each piece, on the upper face of the one and the underface of the other, about 6 or 8 inches from the end transversely, making what is termed a kerf; andlongitudinally from the end, from two-fifths down, on the same side, so that the pieces lap together likea half dovetail.
