GLUING THE BODY FRAME
_____3. Carefully arrange the side pieces, corner blocks,
heel block and tail block on your plywood clamping board
to see how they fit together (Fig 3).
CAUTION: Orient all parts so the front edges face down-
ward on your flat clamping board. Notice that we have
marked each side piece, and heel & tail blocks, indicating
the proper orientation.
All front edges are marked “SB” for soundboard, and the
back edges are marked “B”.
The corner blocks do not have a front or back, but they are
numbered C-1 or C-2 to fit the corners with those numbers.
Please take the time to study this carefully so your parts will
fit properly.
ORIENT ALL PARTS WITH FRONT EDGES FACING DOWN
_____2. You will find it very helpful to make yourself a perfectly flat
work surface out of 3/4” thick plywood or particle board for use as a
flat clamping pad under the body of the instrument. If you cut it about
1” larger than the shape of the soundboard, you will be able to easily
fit clamps all the way around the perimeter of the instrument (fig 2a).
Another idea that works well is to use a rectangular piece about 22” X
28” (fig 2b) so you can clamp with bungee cords, as shown in steps 21
and 31. We use both types, as you will see in various photos. Just make
sure the clamping pads are good and flat.
It is smart to skim through the entire directions before beginning, just to get an overview of the project. You may need to gather
more tools or purchase a few optional decorations or accessories to enhance the finished instrument. Now is a good time to
make those plans so you can avoid delays later. Here are a few of the small items you’ll want to have on hand:
sharp chisel wire cutter 8 spring clamps 2 long-reach clamps for braces
masking tape (blue) clothes pins 8 small c-clamps 40 ft bungee cord (3/16” dia)
carpet tape razor knife triangle file router with flush-trim & inlay bits
straight-edge 6” rat tail file flat mill file wood filler (mahogany color)
_____4. Begin by gluing and clamp-
ing the four corner blocks to the two
side ribs, taking care to orient them
at the correct ends, as printed on the
wood (each side rib gets a C1 at one
end and a C2 at the other end).
CAUTION: The larger part of the
corner blocks will face the inside of
the body, as shown in fig 3. Don’t
glue them to the outside of the sides!

Clamping wedges are provided to help compensate for the angles of the
parts, as shown in fig 4b. HINT: If you cover the wedges with Scotch
tape, they won’t get stuck to the other parts when clamped.
Use either spring clamps or small c-clamps for this step (fig 4c), mak-
ing sure the parts are fully seated together and flat on the edges. Use a
wet rag to clean off excess glue that squeezes out. This helps you see
the joints clearly, as well as prevent messy glue spots on the instrument. Clean off excess glue
