Attaching Braces

The sound board and back braces must be installed before gluing the body together. The braces, sound board, and back come pre-mea- sured and marked with layout lines as shown in Figures 9 and 10.

The braces are roughed to size at the factory, but some fine tuning is necessary for the best fit. The back braces are meant to have a slight curve, which gives the back of the ukulele a belly, improving its sound quality. The sound board braces on the other hand are meant to be flat.

Note: Leave the braces long during assem- bly. They will be cut to length in a later step.

To prepare the sound board braces:

1.Mark the center on the side of each brace, as shown in Figure 11. Transfer any identifica- tion markings to the side of the brace as well.

2.Using a straightedge, check the back of both the sound board braces for flatness.

If the braces are flat, proceed to the next section.

If either brace is slightly rounded, proceed to Step 3.

3.Using a straightedge and pencil, mark a line as shown in Figure 12.
