Yes, only one template. I use an anchored wire to make these cuts.
The result is an airfoil that is thinned toward the tip as well as
being tapered. You simply have to decide if you want a flat trailing
edge, flat leading edge, or a taper that is somewhere in between
(leading and trailing edges taper). I mounted a bolt at the end of
my cutting table from the bottom of the table. It is held in place
with a nut on top. Two wing nuts are screwed onto the bolt (lower
one is flat side up, upper one is flat side down). The cutting wire
has a loop tied into one end and that is sandwiched between the two
wing nuts. The height of the sandwich is at the midline of the
airfoil (measured at the template end and replicated at the bolt). I
cut my core to the planform and place it on the table. If one edge
is flat, I use that as the reference point and align the flat side
with the taught cutting wire (the "free" end of the wire is attached
to a wooden handle and pulled tight). I then move the wire to the
tapered side and adjust the foam block (nearer to or farther from the
bolt) until both sides have the wire flat against their face when
pulled tight. Attach the template, attach power to the wire on
either side of the foam block, apply power, pull wire tight, and cut
by hand at a steady speed.
You can also do this with your commercial cutter, or home-built
hands-off cutter by anchoring one end (of a long-long bow) and only
attaching one pulley system to pull the wire through the block.
Good luck.
