The first step is gluing the top and back braces . The back 
has three braces . The number of top braces depends on 
the model of your ukulele: the Soprano has fewer than the 
Concert or Tenor .

Transfer the brace plan to the wood
The full-size plan shows where to place the braces . Back 
braces are printed in gray, and top braces in white . 

The heavy black line on the plan is the actual shape of 
the ukulele . Outside of this is a dotted line indicating the 
slightly oversize top and back wood . Cut the plan out on 
this dotted line . 

Decide which side of the top and back you prefer to have 
facing outward . We’ll mark brace locations on the opposite 
side, which will become the inside of the uke .

Lay the plan over the back or top, centering it on the wood . 
Transfer the plan’s centerline to the upper and lower edges 
of the top and back wood . 

Use a pushpin to poke small holes into the wood at the brace 
ends . Connect these holes with a pencil and straightedge, 
and you have the brace locations marked for gluing . 

Save the plan drawing for use later when building the body . 

Clamps
You’ll need at least one clamp big enough to reach onto 
the top or back for clamping braces . Smaller clamps are 
good for the brace ends . Wooden clothespins make great 
small clamps, if you wrap them with rubber bands for extra 
strength . 

You don’t need many clamps . TiteBond III dries fast, so 
gluing the braces goes quickly even when clamping one 
brace at a time .

Use pieces of wood to protect the uke parts from the clamps . 
Cauls of scrap wood also distribute clamping pressure more 
evenly . Cauls also can be placed across multiple braces, so 
one clamp can glue two or even three at once . 

A piece of wood clamped to your table makes a very handy 
gluing rig . It holds the back and top in place while giving 
you lots of room to arrange clamps .

Start with the back braces
The back bracing is simpler than the top, so that’s a good 
place to start . When you move on to the top braces, you’ll 
be familiar with clamping and gluing .
