Find the point
of the lateral cartilage where it starts to turn down.
Mark that
spot. A black marker works well on a light colored leg.
For dark or black legs, Whiteout correction fluid works well.
Hold the plexiglass
so the 3.5 cm mark is on the mark you just made at the lateral cartilage.
Make a mark at the bottom of the plexiglass on the heel. This will be
the 3.5 cm mark for heel height.
Line up the
30 degree mark of the plexiglass on the hair line and
the bottom of the plexiglass on the heel mark you just made.
Mark along
the bottom of the plexiglass. In a foot as long as this one the mark
may go from the heel to the toe. In many feet, however, the mark will
go from
the heel and end somewhere in the quarters. Just make sure the 30 degree
line is on the hairline and the bottom edge of the plexiglass is on
the 3.5 cm heel mark.
Find the true
tip of the frog. This may mean paring it a bit until you can
see it at the frog/sole juncture. Then measure 1 cm in front of the
apex.
Make a mark.
Use the edge
of the plexiglass or any straight-edge and line up with
the mark you just made 1 cm in front of the frog apex.
Draw a line
from wall to wall.
Between the line and the toe is the moonsickle area.
Find the midpoint
of the frog and make a mark.
Mark a line across the entire foot with a straight-edge.
Between the
two line is where you will trim
along the frog down to the frog/sole juncture.
(the angle of this shot make it look like the line is not mid-point
of the frog...
but it is...I was standing on my head at the time!!)
