PREPARING THE SOUNDBOARD
____8. Take note that the soundboard is punch marked on
the outside surface (front) of the board.
Using a hand drill or drill press, drill the lowest
and highest punch marks with a 1/8” drill bit. These
holes will act as a guide for the reinforcement strip.
Perform the drilling on a workboard to prevent the
wood from tearing out on the soundboard, and hold
the drill perpendicular. (fig. 8a)

Workboard
____9.
Flip the soundboard so the inside faces up.
Connect holes with a straight edge and mark with
a pencil. This line will act as a reference for gluing the reinforcement bar. (fig. 9a) Dry fit the
reinforcement bar and trace around each end with a pencil on the inside of the soundboard.
Be sure that the reinforcement bar covers the highest hole. (fig. 9b, c)
____10. Gather weights and clamps for
pressing the reinforcement bar
and dry fit the reinforcement bar
with the clamps as well.
Apply glue along the length of the
reinforcement bar and tape on
both ends to prevent slippage once
the weights or clamps are added.

NOTE:
You can sand the inside of the soundboard, but this is not neccessary. If you
choose to sand the inside, make sure you keep a level surface.
CAUTION:
If the reinforcement bar is covering the
punch holes - you need to flip the soundboard over.

Then you can add the weights or clamps. Make sure that you are continuing to utilize your
workboard, as it helps keep the soundboard and reinforcement bar flat during the clamping
process. (fig. 10c, d)
