1. OVERVIEW
The Jointmaker Pro is the world's first stationary
hand crosscut saw and will accurately allow you to
make most of the cuts required in wood joinery plus
a myriad of other sawing applications.
Consisting primarily of two independent linear
tables mounted over specially designed,
fine-toothed saw blades, the Jointmaker Pro
redefines the meaning of "cut by hand”. Using no
electrical power, the Jointmaker Pro is designed
specifically to make precision cuts for the most
demanding craftspeople with as little noise as
possible, and without the need for dust collection.
Understanding how this tool works—what it can
and cannot do—is your key to a successful and
fruitful experience.
Cutting wood accurately by hand requires a great
deal of practice, a well-made saw with sharp teeth
and yet still remains difficult for many, particularly
those new to the craft or those with disabilities.
With the Jointmaker Pro, people of all ages and
experience levels can achieve results that are
MORE ACCURATE than cuts made with power
equipment. Furthermore, the cuts are unparalleled
in quality creating opportunities for new and
exciting ideas not possible with traditional
techniques.
At this time, please take a few minutes and peruse
the assembly section of this guide to become
familiar with the nomenclature of the Jointmaker
Pro. This will make the remainder of this section
much easier to understand.

SAFETY
Your Jointmaker Pro is no different than any other
sharp tool—usecommonsense!
Although it may seem safe to take risks because
the saw blade is stationary—and the only motion is
provided by YOU —safety should never be taken
for granted.
Etched on the top of each sliding table is a graphic
element that is designed to remind you of the risk
to your fingers. It may seem obvious, but we
strongly recommend keeping your fingers out of
this zone, especially when the blade is tilted.
After you have spent an hour or two using the
Jointmaker Pro we hope you share your new found
ability with other members of your family—this tool
can be enjoyed by many who like making gallery
quality cuts in a noise free environment!
SAW RIGIDITY AND ERGONOMICS
Under all circumstances, the Jointmaker Pro needs
to be firmly anchored to a work surface or attached
to a stand. If the saw moves while cutting your
accuracy and enjoyment of the tool will be less than
optimal.
The front table height of the Jointmaker Pro should
be an inch or so below your belt line. At this height,
you will be able to make a full stroke without undue
stress on your back or arms. If possible we
recommend that the rear of the Jointmaker Pro be
approximately three inches higher than the front.
This incline shortens the stroke of your arms,
increases your ability to see your work and reduces
strain on your lower back during long work
sessions.
WORK HOLDING REQUIREMENTS
Traditionally when cutting wood with a hand saw
you clamp the material to be cut to a workbench or
hold your stock in a vise. With either method, the
stock should always be firmly anchored in order to
achieve optimal, and accurate, results.
The same work holding requirements are true
when making most cuts with the Jointmaker Pro.
The sliding table is analogous to a workbench
surface and the angled trap clamps act as a vise.
These elements become particularly crucial with
the Jointmaker Pro because unlike any other hand
sawing experience, you are cutting from the bottom
up as opposed to top down. Without your stock
firmly anchored to the sliding tables, the negative
feed (the tendency of the wood to ride up over the
top of the blade) becomes difficult to manage with
hand strength alone. In almost all cases, we
strongly recommend that you utilize these work
holding aids for accuracy and blade longevity.
When using the blade in a tilted position, trap
clamping is mandatory.
SAW BLADES & DEPTH OF CUT
All of the saw blades currently designed for the
Jointmaker Pro contain between 350 and 460 teeth
over their length. Because the blade is inclined (the
front of the blade is lower than the back of the
blade) in relation to the table surfaces, each tooth
bears the exact same workload.
For example, a piece of walnut with a 1/2”x1/2”
cross-section can be cut in half with one stroke
using the standard crosscut blade. To correctly set
the blade for this cut, you would adjust the blade so
that the first couple of teeth are below table height,
and the last tooth of the saw blade is set with the
pitch adjustor to approximately 1/32 ’above the
stock of the wood. With the stock held firmly
against the fence, one stroke and the cut is
complete, smooth and accurate. See the Cutting
Guide page 6 for more details.
This example is possible because the standard
JMP crosscut blade has approximately 400 teeth.
Using the stock and set-up described above, each
tooth of the saw has a chip load of just over one
one-thousandth of an inch (.5/400 = 0.00125n). It is
the combination of the chip load, precise linear
movement and blade rigidity that makes
Jointmaker Pro cuts unparalleled in quality or
accuracy.

4
For wider stock (where more teeth are
simultaneously engaged with the stock), multiple
passes are required utilizing a smaller depth of cut
per pass.
For example, 1/2”thick walnut 4”in width would
dictate that you set the saw up with the first couple
of teeth below table height (using the hand crank at
the front of the JMP) and the last tooth
approximately 1/16 ”above the table (using the
Pitch Adjustor). With this set-up, it will take 10
passes to cut the stock in half. Between each pass
the blade is raised approximately 1/16". In this
situation, the 400 teeth are required to cut
approximately 1/16th of material per pass. The chip
load is now one ten-thousandth of an inch
(.0625/400) per tooth! However, because the board
is 4”in width, more teeth are engaged during each
pass creating more resistance. More resistance
requires smaller bites for the cuts to feel almost
effortless.
The only "guide”we can provide for tailoring your
technique to accommodate the myriad of different
species and sizes of wood is to emphasize that the
effort required to cut any wood should be minimal.
Harder material or wider stock requires smaller
bites and more passes. If you are overly
aggressive, you will dramatically shorten blade life
and the quality of your cuts will suffer. After a short
"getting acquainted”period all of this will become
second nature.
As a reference, one full revolution of the crank
handle raises the blade exactly .055 ”or slightly
less than 1/16 ”. You will discover that extremely
dense woods will require blade height adjustments
as small as 1/8 of a revolution between cuts and
some softwoods can be cut with 3 full revolutions
for each pass! It is your job to discover the optimal
settings for ease of use according to your own
preferences and applications.
You will soon discover the general purpose
cross-cut blade that ships with the JMP will do the
majority of cuts (.4mm x 28). The 16 teeth per inch
rip blade is useful for cutting tenons and dovetails if
you have many to cut. The .3mm crosscut is ideal
for small stock but does not track well in deep cuts
(it is so thin it will follow the density changes of the
wood being cut).
You will know when your blade is dull because of
the resistance you sense with cutting or the quality
of the cut is not smooth to the touch. Blades are not
designed to be sharpened —they are disposable.
Contact your local distributor to avail of
replacement blades.
THE FENCES AND HAND PLACEMENT
The Jointmaker Pro utilizes two fences that are
normally bridged by a sacrificial wooden fence. The
only time you do not use both tables is when you
are cutting face miters.
There are two sacrificial fences, one is straight and
the other has an angled face. Use the straight
fence for joinery and the trap fence for crosscuts.
Werecommendthefencesbelockedinthe
forward position for all cuts of 4”or less in width.
For stock wider than 4 inches, slide the fences to
the back position.
When possible, your hands should be directly over
the center of the dovetailed ways on each side of
the saw blade. As your experience with the saw
grows, you will learn that you can use one hand to
make your strokes and the other will be raising the
blade on the return stroke. This combination is
efficient and fast.
We recommend that your first cuts be made with
both hands employed during the sawing strokes.
NOTE: The table tops are orange for a reason; you
can write on them with a pencil. For example, once
you have the fence set to 90 degrees, you can
scribe a pencil line along the fence and use this line
as a reference.
MISTAKES WE HAVE MADE
We have ruined several blades because of human
error. Please review this section to learn from our
mistakes.

5
•MAKE SURE THE KEEL, THE FENCES, AND
YOUR CLAMPS are all TIGHT before sawing.
This will eliminate 80% of the mistakes we have
made.
•Lower the blade below table height after each
session. Horizontal surfaces attract things, and the
blades are easily damaged with contact by metal
objects or heavy wood.
•It is helpful to have an old toothbrush nearby to
periodically clean wood fibers that may be
embedded in the gullets of the blade. This is
particularly helpful when using the rip blade.
•Lastly, enjoy the fact that you are the motor. Let
the saw do the work and use as many passes as
needed to accomplish your tasks. We
GUARANTEE that aggressive sawing techniques
are going to be expensive for you.
WARRANTY
Your Jointmaker Pro is fully warranted for defects
in workmanship. Please notify your local distributor
immediately if you have encountered a defective
component so it can be replaced immediately
LUBRICATION
Please review the lubrication guide on page 6 for
all the lubrication locations (this is done once or
twice a year depending on use.) We recommend
using the lubrication included with your Jointmaker
Pro.
YOUR FIRST CUT
Once your Jointmaker Pro is properly set-up, you
are ready to make your first cut.
We recommend practicing your first cut on a small
dowel rod, 1/4 ”一1/2” in diameter. Set the
leading edge of the crosscut blade slightly below
table height, and using the pitch adjustor, raise the
rear of the blade until it is slightly taller than your
stock.
Beforeyoumakeacut,takeacoupleof"dryruns”
to get a feel for the resistance of the tables in
motion. When comfortable, hold your material
firmly against the fence and with one smooth,
controlled push, cut your stock. You will discover
after just a few passes the rhythm required for
incredible results. As the density/ width of your
stock changes, you will sense the need to reduce
depth of cut and increase the number of passes.
THERE ARE NO GUIDELINES other than the
feedback you sense from the cutting action will
dictate any adjustments you will need to make for
effortless cutting.

4. Operation
Note: This chapter states the basic operation of Jointmaker Pro. However, before the formal use, the
Jointmaker Pro must be calibrated referring to Chapter 5 to ensure its high accuracy and excellent
performance.
4.1 Adjusting the Blade Height (Fig. 3)
As shown in Fig.3, rotate the blade height adjustment handle until you get desired blade height. For each
turn of the handle clockwise or counterclockwise, the overall height of the blade will increase or decrease by
1.25mm.
Note: To prevent the keel being rotated while rotating the blade height adjustment handle for high cutting
accuracy, the front and rear keel lock knobs must be tightened (the rear keel lock knob is not shown in Fig.3)
before adjusting the blade height.
Fig. 3
Adjusting the blade height stop (Fig. 3)
The Jointmaker Pro is equipped with a height stop to prevent the lead screw being damaged while lifting.
The lowest and highest positions of the stop has been set at factory. To operate repeatable cutting by
certain height, adjust the highest position of the stop as following steps:
1. There are three nuts on the front shaft, the two closest to the front plate are jam nuts (need no
adjustment) and the third nut that can be adjusted for different height requirements receives the height stop.
2. With the blade at the desired height and pitch, attach the Height Stop as illustrated. The top of the Height
Stop should be flush against the bottom of the keel and fully embrace the nut. Tighten Lock Knob. Blade
height will now repeat.
Note:
1. Before any cutting operations, the starting position of blade must be under the table, that’s why the
lowest position of the height stop has been set at factory and should not be adjusted in any circumstance.
2. Be careful when turning the blade height adjustment handle, too much force can cause the bevel gears
to strip after the blade spin has reached the max./min. Height (or if there are any binding issues).
3. If the red height stop is removed, then please be aware that the orange blade holder can come into
contact with the top/bottom of the keel assembly and potentially damage the keel if not properly operated.

4.2 Adjusting the Blade Pitch (Fig. 3)
As shown in Fig.3, you can adjust the blade pitch by turning the blade pitch adjustment knob. (The Blade
Pitch increment of one turn is 0.05”)
Note:
1. If the pitch was set too aggressive, you may get your material stuck on the blade , which may ruin the
blade. When this happens, do not attempt to retract the stock by moving the tables backwards, try lowering
the blade directly out of the cut.
2. The very best practice is to start with a pitch that is too low and gradually increase it to an optimal pitch.
Please refer to the Cutting Guide on page 6 for more details.
3. The front blade teeth must be lower than the table while adjusting the blade pitch.
4.3 Adjusting the Blade Angle (Fig. 4)
Loosen the two keel lock knobs (the rear keel lock knob not shown in Fig.4), grasp the middle of keel and
swing to get the desired blade angle, then tighten the two keel lock knobs.
Note:
1. Before any cutting operations, make sure that the blade whose angle is adjusted will not interfere with
the fence.
2. After each adjustment of the blade angle, the parallelism between the blade and table travel should be
inspected and calibrated according to the following steps:
a. Position a hex key wrench (or a hard card) against the fence. Lightly touch the end of the wrench to the
leading edge of the saw blade (as illustrated in Fig. 8).
b. Slide the table slowly, inspect the parallelism between the blade and table travel.
c. If any deviation in parallelism occurs, slightly loosen the keel lock knob on the deviation side, and slightly
tap the keel to complete the adjustment of the parallelism.

Quick angle position stop
There are four quick angle position stops below the dial which are used to locate the common angles
quickly. Loosen the position stop lock screws by a hex wrench, the position blocks can be slid to desired
angles, then tighten the lock screws. When the position blocks are not needed, flip them down.
