Getting the most from your chisels
To hand-cut a mortise with a mortising chisel, begin by chopping out chips between your scribed lines, leaving 1/16" at the ends. Move the chisel about 1/8" at a time, and strike it with a mallet. Then pry out the chips. Make a triangular pattern to the desired depth; then begin back-cutting the rest to match that depth. Finish by cutting away the remaining 1/16" at each end.
