Assemble the body

Place the bent sides into the body mold, with their ends 
butted together at the center . Now you can see the body of 
your ukulele taking shape! If the sides don’t precisely match 
the body shape on the plan drawing, don’t worry . A little vari-
ation between ukes is fine . As long as the side curves match 
each other nicely, you’ll have a great looking instrument . 

The corner braces will hold your sides nicely square to the 
baseboard, so the body doesn’t “lean” in one direction . If 
you like, use a square to double-check this . 

The neck block and tail block are the same size and shape, 
so you can use either block at either end . Press these blocks 
against the side joints with sturdy clamps . Do your dry run 
before using glue . A piece of waxed paper between the 
sides and the body mold will prevent accidentally gluing 
the sides to the mold . 

The neck and tail blocks need to be the same height as the 
sides . If yours are taller than the sides, trim them with a saw 
or chisel . This is easier to do now than later . 

Glue the sides and blocks 
When you’re comfortable with your clamping setup, put glue 
on the neck and tail blocks . Put a little glue on the narrow 
edges of the sides that butt together, too . 

If the neck and tail blocks quickly absorb the glue, add more 
to make sure you have a wet gluing surface . You don’t want 
a glue-starved joint . 

Clamp the blocks and sides, and let them dry for 45 minutes . 
Use warm water to clean up any glue squeezeout while it’s 
still wet .

Install the linings
The flexible wooden linings will be glued to the edges of the 
sides, flush with the top and back . These strengthen the body 
and provide a wider surface for gluing the top and back . 

On guitars similar linings are called kerfing, and kerfing 
clamps are made for gluing them . Rubber-banded clothes-
pins make great substitute kerfing clamps for this kit .
