Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.

There is potential danger when operating
woodworking machinery. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use any machines with
respect and caution to decrease the risk of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.
Strings
No list of safety guidelines can be complete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
tools and any machinery with caution and
respect. Failure to do so could result in serious personal injury, damage to equipment,
or poor work results.
Model T33949/50/51 (Mfd. Since 09/23)

SECTION 1: SAFETY
Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glasses are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of
the American National Standards Institute (ANSI).
Because there are various ways to cut and join wood, you can make substitutions for the methods
stated in this plan. We try to suggest the easiest methods possible. However, only you know your skills
with each piece of machinery. Never compromise your safety by using a cutting method with which you
are not comfortable. Instead, find an alternative approach that will yield the same result.
These instructions assume that you are intimately familiar with the safe operation and use of woodworking machinery and woodworking tools, and understand the techniques used to reproduce this project.
If you do not qualify for both of these criteria, STOP building this project for your own safety. Read and
understand the owner’s manual for the machinery you intend to use, take a woodworking class or visit
your local library for more information. Woodworking machinery and tools are inherently dangerous,
because they use sharp edges that can and will cause serious personal injury including amputation
and death. Do not underestimate the ability of these tools and machinery to cause injury. Never operate any tool without all guards in place and always wear approved safety glasses. For your own safety,
please heed this warning.

SECTION 2: SETUP
Unpacking
This instrument was carefully packaged for safe
transport. When unpacking, separate all enclosed
items from packaging materials and inspect them
for shipping damage. If items are damaged,
please call us immediately at (570) 546-9663.
IMPORTANT: Save all packaging materials until
your are completely satisfied with the instrument
and have resolved any issues between Grizzly or
the shipping agent. You MUST have the original
packaging to file a freight claim. It is also extremely helpful if you need to return your instrument.
Wear safety glasses during
the entire setup process!
Planning &
Preparation
Total time building this instrument will vary on
many factors. Variables such as glue manufacturer's instructions and curing time, temperature and
humidity at the time of building, and your schedule
are just a few of the factors that can affect the
length of time spent on this project.
Perhaps the biggest determinant of time spent
completing this instrument will be the type of finish and the finishing process used. Finishing this
instrument can be as simple as applying a single
coat of stain or lacquer that can be done relatively quickly, up to a multi-coated finish that takes
weeks to harden.
Careful planning and budgeting ample time will
make this project easier and ensure you end up
pleased with your results. Good luck building your
instrument, and Grizzly hopes it turns out looking
and sounding great.
Needed for Setup
The majority of the wooden components in this kit
are fully machined from the factory and are ready
for assembly. A small amount of sanding and finishing is required to complete your ukulele.

SECTION 3: SANDING
Body
The ukulele body was assembled and rough
sanded at the factory. However, no finish has
been applied. The joint where the neck meets the
body and the sound hole should NOT be sanded.
For best appearance be careful not to round the
edges of the ukulele body.
To sand body:
1. Sand body with #180-grit aluminum-oxide
sandpaper until there is a consistent scratch
pattern on entire surface.
Note: When hand sanding, always sand in
same direction as wood grain.
Repeat Step 1 with #240-grit sandpaper.
2.
3. Repeat Step 1 with #320-grit sandpaper.
Neck
Like the ukulele body, most of the ukulele neck
has been machined and rough sanded at the
factory. However, the neck headstock can be customized to reflect personal taste. Additional cutting, inlay, or design work can give a ukulele that
personalized custom look that makes it unique.
Note: If you do choose to customize the neck
area, take your time with this sub-section and
consider testing ideas on scrap wood before performing the work on the actual headstock.
To sand neck:
1. Perform any custom cutting, inlay, or design
work to neck headstock.
2. Using sanding technique described in Body
section, sand ukulele neck.
Wipe body with a damp, lint-free cloth. Wiping
4.
workpiece with a damp cloth before final
sanding helps to "raise" wood grain; thus,
allowing "raised" grain to be sanded smooth.
Once body is dry, repeat Step 4.
5.
Wipe body with a tack cloth to remove all
6.
remaining sanding dust.
To reduce risk of eye injury from airborne
particles or lung injury from breathing dust,
always wear safety glasses and a respirator
when sanding.
Note: DO NOT sand fretboard mounting sur-
face. This will affect playability of ukulele and
could lead to irreparable damage.
Bridge
The bridge has been sanded and finished at the
factory. Sanding and finishing the bridge is not
nec essary.
Model T33949/50/51 (Mfd. Since 09/23)
-7-
Fitting Neck to Body
4. Sand until neck profile matches ukulele body
profile (see Figure 6).
Attaching the neck to the ukulele body is the most
crucial part of the assembly process. Attaching
the neck incorrectly could result in difficult bridge
and string adjustments. Additionally, it can exert
stress on the instrument that could lead to irreparable damage.
The neck will need to be shaped by sanding
before it is ready to attach.
To sand neck:
1. Attach sandpaper with masking or painter's
tape at location shown in Figure 4 below.

Note: DO NOT sand fretboard mounting sur-
face. Sanding fretboard mounting surface will
affect playability of ukulele and could lead to
irreparable damage.

SECTION 4: ASSEMBLY
Attaching Neck to
Body
As noted earlier, attaching the neck to the ukulele
body is the most crucial part of the assembly
process.
Make sure you have shaped the mounting surface of the ukulele neck as explained in Fitting
Neck to Body on Page 8 before attempting
to attach it to the ukulele body.
ALWAYS follow adhesive manufacturer's
instructions for your safety and best results.
To attach ukulele neck to body:
1. Place ukulele body and neck face down on
workbench.
2. Place layer of masking or painter's tape
lengthwise down center of back of ukulele
(see Figure 7), and trim flush at endpoints.
3. Repeat Step 2 for back of neck (see Figure 7).
5. Use a pencil to lightly draw center line over
masking tape on ukulele neck and back
(see Figure 7).
6. Apply a thin, even layer of wood glue to mat-
ing surfaces of ukulele body and neck.
Align center lines (see Figure 7).

8. Use a ratcheting band clamp, or binding tape,
to secure ukulele body and neck together
(see Figure 8) and let assembly dry for at
least 24 hours.
Center Line
4. Using a ruler, measure to determine center line
of both ukulele back and neck (see Figure 7).
Model T33949/50/51 (Mfd. Since 09/23)
Note: If possible, clamp both ukulele and
neck in position on work surface, and wipe
away any excess glue immediately. Failure to
do so can mar finish in this area.

2. Lightly sand top face of neck with #120-grit
sandpaper.
Note: Try to avoid sanding body while sand-
ing top face of neck.
3. Remove sanding dust from both pieces with
tack cloth.
4. Apply a thin layer of wood glue to back of
fretboard and position it on neck.
5. Make sure fretboard is centered across width
of neck, and 14th fret is positioned over neckto-body joint (see Figure 10).
10. Using #320-grit sandpaper, sand bottom of
neck until smooth with bottom of ukulele.
11. Wipe bottom of ukulele neck with a damp,
lint-free cloth and let dry.
Wipe ukulele bottom and cut line with tack

6. Secure fretboard in place with C-clamps or
rubber bands and wood stock, as shown in
Figure 11. Use wedges if necessary to
ensure a tight fit. Wipe off any glue overspill
with a damp, lint-free cloth.
Figure 11. Fretboard secured to neck.
7. Let glue dry a minimum of 24 hours, then
proceed to Step 8.
Determining Bridge
Location
The bridge is glued directly to the top of the body
at a distance that is consistent with the scale
length of the instrument. This instrument's scale
length is calculated by measuring the distance
from the bottom edge of the nut, where it butts
against the end of the fretboard, to the center of
the 12th fret, and then doubling that number.
It is important to leave an area of the sound board
unfinished that is slightly smaller than the footprint
of the bridge. This will increase the strength of the
glue joint that attaches the bridge to the sound
board. The reduced size of this area allows the
finish of the ukulele to be consistent around the
bridge.
A template has been provided for placement
of the bridge. In the event the template is
misplaced or damaged, contact Grizzly for a
replacement. However, it is possible to correctly
place the bridge without the template. Instructions
for attaching the bridge with or without the template are included.
8. Use #320-grit sandpaper or a fine file to sand
edge of neck flush with edge of fretboard. Do
this gently and slowly to avoid sanding
fretboard.
Locating Bridge With Template
1. Place template at top of fretboard
(see Figure 12 on Page 12), making sure
fretboard and sound hole are clearly visible
and properly aligned.
2. Remove template and place a layer of mask-
ing or painter's tape on instrument where
bridge will be located.
Note: Make sure taped area is larger than
bridge footprint.
3. Place template (see Figure 12 on Page 12)
back in position and use a pencil to lightly
trace top and side lines for bridge.
4. Remove template (see Figure 12
on Page 12) and place bridge according to
marks made on tape.

Installing Nut
The nut is located at the top of the fretboard and
holds the strings in place. The nut can be held in
place with string tension, or it can be spot glued
in place for more security.
If you prefer to glue, we recommend using wood
glue so that future adjustments can be made. For
a more permanent bond, super glue can be used,
but future adjustments will be more difficult.
Tape

Tip: Angle knife inward as you cut.
ALWAYS follow the adhesive manufacturer's instructions for your safety and best
results.
To install nut:
1. Test fit nut on top of fretboard.
Note: Curved part of nut should face head-
stock.
2. Apply a spot of glue to top of fretboard and
neck, then press nut in place and secure
(see Figure 15).

Finishing supplies are not supplied with the ukulele kit.
There are many resources (books, videos, websites) that discuss ukulele finishing. Grizzly recommends consulting these sources before finishing your instrument.
Listed below are a few general tips that can be
helpful in finishing your instrument.
Painting/Finishing Tips:
• Always work in a well ventilated area when
using finishing materials.
• Wear an ANSI-approved respirator mask and
safety glasses when using finishing materials!
• Fabricate hooks from metal hangers to suspend ukulele components during finishing
process.
Masked Fretboard
and Nut
Figure 16. Masked fretboard and nut, filled sound
hole, and masked bridge position.
Carefully press all masking tape edges securely
to ukulele pieces. Finish can seep under these
edges, especially near corners, uneven edges,
and where frets meet fretboard.
Note: Failure to properly mask these areas could
result in irreparable damage to ukulele.
• Several thinner coats usually produce a nicer
finish than one heavy coat.
Note: Always follow finish manufacturer’s
instructions.
• Dust particles suspended in air will settle on
wet finishes, resulting in less than satisfactory results. To avoid this problem:
1. Have ukulele components positioned for
finish application upon entering room.
Leave room where finishing will take place
2.
completely undisturbed for 24 hours prior
to applying finish.
Avoid making unnecessary movements
3.
upon entering finish room.
Apply finish to desired ukulele parts and
4.
immediately leave finish room.
-14-
DO NOT return to room until specified dry-
5.
ing time has elapsed.
Model T33949/50/51 (Mfd. Since 09/23)
Installing Bridge
Remove the tape from the masked areas in
preparation for installing the bridge. Refer to
Page 11 for the necessary measurements to
locate the bridge.
We recommend using wood glue so that future
adjustments can be made. For a more permanent
bond, super glue can be used, but future adjustments will be more difficult.
Installing Bridge with Clamp
1. Remove masking tape from bridge location.
Apply a thin, even layer of wood glue or super
2.
glue to bottom of bridge.
Position bridge on pre-determined bridge
3.
position and gently press bridge down making sure that bridge pin holes line up.
Installing Bridge with Wood Blocks
If a bridge clamp is not available, it is possible
to install the bridge using wood blocks and large
rubber bands.
1. Follow Steps 1–3 in Installing Bridge with
Clamp on this page.
. Carefully position wood blocks over bridge
2
and under back of ukulele, then secure with
rubber bands (see Figure 18).
Clamp bridge down with a bridge clamp or
4.
large depth C-clamp (see Figure 17).
Note: DO NOT overtighten clamp.
Figure 17. Bridge clamped in position.
5. Check to make sure bridge is still in correct
position and adjust if necessary.
Let dry for a minimum of six hours.

Fitting Bridge Pins
T-Handle
. Place T-handle reamer in (1) bridge pin hole
4
and gently twist reamer clockwise, making
one complete revolution (see Figure 20).
Now that the bridge is securely attached, it is time
to prepare the bridge for bridge pin fitting.
To protect the finish on your instrument you
should mask off the top of the ukulele around the
bridge before proceeding with these instructions.
Unless otherwise indicated, we strongly recommend using a drill press for the majority of drilling
to obtain the most precise results. However, an
electric/cordless drill fitted with a depth stop or a
drill stand can be used if you do not have a drill
press.
To fit bridge pins:
. Carefully drill (4) holes in bridge using 5⁄32"
1
Forstner bit at bridge pin hole locations
(see Figure 19).
Note: Be careful to keep drill straight, and
drill only until you break through to sound
chamber. Do not drill through back of ukulele.
Note: It is important to not take too much
material out of hole. Bridge pins should be
snug fitting.

Installing Tuning
Machines
The supplied tuning machines are mirrored pairs:
two for the left side of the headstock, two for the
right. Each tuning machine consists of the parts
shown in Figure 23.
Note: Unless otherwise indicated, we strongly rec-
ommend using a drill press for drilling in this manual to obtain the most precise results. However,
an electric/cordless drill fitted with a depth stop or
a drill stand can be used if you do not have a drill
press.
To install tuning machines:
1. Using a non-marring mallet, tap each of (4)
machine seats with washers into pre-drilled
holes on front of headstock.
2. From back of headstock, slide tuning machine
through headstock and seat (see Figure 23).

Tuning Peg
The string height is the distance between the
top of the fret and the bottom of the string
(see Figure 27). Correct string height is crucial
for maximizing the playability of the ukulele.
Measurements are taken at the 1st and 12th frets.
You can use a variety of tools to check string
heights on ukuleles, including feeler gauges, a
fine ruler (
which are available at your local shop or online.
However, to set string height on a ukulele, all you
need is some pocket change.

nut and saddle until correct string heights are
reached. Hand-sanding prevents removing too

To set string height:
1. Using a dime as a gauge, measure string
height at each string along 1st fret
(see Figure 28).
— If string heights are approximately thick-
ness of a dime, then continue to Step 2.
— If string heights are more than height of a
dime at 1st fret, this is an indication that
height of nut needs to be reduced. Proceed
to Step 3.
2. Using a stack of three pennies, measure
string heights at 12th fret (see Figure 29).
— If string heights are approximately thick-
ness of three pennies, then continue to
Step 5.
— If string heights are more than height of
three pennies at 12th fret, this is an indication that height of saddle needs to be
reduced. Proceed to Step 3.

Tuning
Tuning is the most important concept of playing
a ukulele. If the ukulele is not in tune with itself,
or the other instruments in an ensemble, the
resulting music will not sound pleasing to the ear.
Having a good understanding of tuning is essential to maximizing the full potential of any ukulele.
Important issues to consider when tuning a
ukulele:
• Get into the habit of tuning the ukulele every
time it is picked up to be played.
• Always tune the strings "up." The final tuned
tension of each string should be reached
while tightening the string, not loosening it. If
the string is tensioned too far, loosen the tension and tune "up" again.
• The easiest way to tune a ukulele is using an
electronic tuner. There are a wide variety of
these available in music stores, or online with
a wide variety of prices as well. However, with
practice, you can learn how to tune a ukulele
by ear–a skill used by many accomplished
ukulele players.
Ukulele Setup
Congratulations – construction of your ukulele kit
is now complete!
At this point you may want to consider setting up
the ukulele to your own personal specifications.
"Setting up" your ukulele can be as simple as
swapping out the strings provided to the brand
that is your personal favorite.
• The goal when tuning is to make the strings
in tune with one another. Standard tuning is
shown in Figure 30.

Setting up your ukulele can also be a bit more
complicated and technical. You can modify or
adjust the ukulele to match your preference for not
only strings, but string height, or action, through
nut and saddle adjustments, and raising or lowering the bridge, to name just a few.
There are plenty of resources including books and
websites that will guide you through that process.
It is also possible to have your ukulele taken to a
music shop or licensed luthier and have them set
up the ukulele for you.
Again, congratulations and enjoy your new ukulele!
