A line on the body shape template marks the ukulele’s waist-
line, 4-1/2" from the neck end . Transfer this line to your body
assembly jig, keeping it perpendicular to the centerline . On
this line, attach two angle brackets to support the sides and
hold the waist in position . Use 1/2" screws to attach these
brackets in position to just touch the waistline .
Small finishing nails around the base can be added now or
later when gluing the top . During that step, rubber bands
wrap around the nails and over the body in the jig, adding
uniform clamping pressure while gluing .
This simple jig holds the ukulele for gluing, and ensures that
the sides are properly squared up with the top and back .
From 3/4" plywood, cut pieces for your jig:
body jig base: 11" x 13-7/16"
neck end side wall: 11" x 2-3/8"
tail end side wall: 11" x 2-1/2"
The size difference of the side walls is because this ukulele
kit is designed with a tapered profile: the body’s tail end is
slightly deeper than the neck end .
Draw a centerline down the length of the body jig base .
Measure accurately, because you’ll use this line to guide
you in building .
Assemble the two side walls on the neck and tail end of
the base so the interior walls will be 12" apart (pictured) .
Use a square to be sure the sides are perpendicular to the
centerline . Glue and fasten each wall with two drywall screws
(from the underside of the base), and let dry for 3 hours .
When the glue has dried, draw the centerline onto the ends
of the jig, continuing it from the base onto the walls and
tops of the side walls . Keep the lines square—you’ll use this
centerline for aligning pieces during construction .
Included in these instructions is the body shape template
and bracing pattern (center page of this book) . Carefully
remove this page and cut out the body shape . Save the body
shape template; you will be using it again later . Trace the
body shape onto the base, aligning it with your centerline .
The ends of this body shape should touch the two side
walls .
Assemble the body
Body assembly jig
Two angle brackets support
the sides and hold the waist in
position (right). Wooden cauls
can be crafted for the same
purpose (above).
