After the shelf has been established the tongue where the passant seats is carved.
The passant is fit and the bottom sides are hand planed to match the width and orientation of the passant. The front of the frog is filed square and the final length of the passant is established. The frog is then cut to final length and the heel is rounded, first by making a series of facets. Next the top of the frog is planed back into symmetry.
The throat has been carved which allows the maker to establish the placement of the pearl eyes. A .9 mm pilot hole has been drilled to use as a guide for the cutter that will make the recess for the eye.
The flanks or creasage of the frog are hollowed with a Japanese gouge to a beautiful curve. In the next post we will move on to the pearl eyes and beyond.
