A Bad Headstock Break On a Sigma- Page 2
The idea is to remove about 1/8" from
the back side of the headstock,
continuing down onto the neck.  This
will be replace with a piece of wood
overlayed onto the back (hence the
backstrap overlay).  I use the Wagner
Safety Planer to remove the material
from the back of the headstock.
The Wagner Safety Planer is
the repairer's friend.  Cheap,
safe and easy to use.  You will
need a good dust collector,
though.
I have a good measurement of the
thickness of the headstock along with
the faceplate tacked on.  Grasping the
neck, I hold the faceplate tight against
the Wagner base and feed the
headstock through.  It really is not as
hard as a souds.  Here is the result.
After the Planer, I will carve the neck to
match the headstock.  I want to go
pretty far into the neck so that the
backstrap gives the joint strength.  I
also want a nice smooth transition from
the headstock to the neck so that I
don't have to bend the wood too far.  I
start with carving knife at first, then a
rasp file, and finally sanding block.  
The  key is to get a smooth, even joint
for gluing.
