Actually, this stem piece is not the true original, but is from an earlier repair done several years ago. The main problem with it was that it was not wide enough. This made the stem too narrow and gave the boat an blunt, clunky look.
The points where the rabbet and bearding lines intersected the reference lines were then transferred to the new stem. Every second section was chiselled out, using a fid the same thickness of the plank to determine the vertex. Once this was done, the remaining squares were done so that they would merge with their neighbours.
