19) Mark the ends of bracing that will touch the side kerfing 3/16”
thick or simply lay a sharp pencil flat on the back and mark the ends
of the bracing.
20) Scallop the end of the bracing to the 3/16” mark.
21) The shoulder brace can be left thick as this does not
dramatically change the overall sound. Using a sharp chisel, follow
the existing curve of the brace and reshape the end to be 3/16” thick.
Note: Be sure to review pages 9-11 for tips and information on scalloping
the braces.
Note:
When you are using a chisel and creating constant downward
pressure to thin your bracing, be sure to rest the top on a hard surface. If
you use a spongy non-skid pad to rest the top on, you risk significant flex
and possible damage to the top. Be careful…be gentle!!
Alternative to Step 19-21: Using a small laminate router, cantilever it
over the workbench on a piece of 1” scrap and use a ½” straight cutter set
at a height that will cut the brace to 3/16” high. (Be sure to cut a test
piece.) With the top face down, pass the ends of the x-braces and
shoulder brace under the cutter to trim the ends. Now scallop the braces
to the new height of the ends of the braces. This method will ensure a
uniform height for all the braces. A Dremel tool with a base and a small
straight cutter could be used to trim the lining, being careful not to cut all
the way through the sides of the guitar. See the attached photo.
22) Use the trim line from Step 7 to cut and remove the excess top
using a sharp saw, preferably a bandsaw.
