INCRA Miter V120 Shopsmith Edition - Manual

Before using the INCRA Miter V120, read and follow all of the instructions
and safety information in this document.
Instructions
Safety
Adjust the Miter Bar for a Perfect Fit in Your Miter Channel
Place the Miter V120 in your Shopsmith’s miter channel. The T-slot
retainer has a rubber O-ring between the retainer and the underside of the
bar to permit tightening the retainer to lock the Miter V120 into your miter
slot. This will allow you to use the Miter V120 as a guide for horizontal boring
or disc sanding. Take care not to overtighten the screw when using the
locking feature. Overtightening can cause the retainer to take a set (a
slight bend). If this happens,
simply turn the retainer upside
down and re-install,
Figure 1.

• When using the INCRA Miter V120
in conjunction with any other tool,
first read and follow all instruc-
tions and safety information in
that tool’s owner’s manual.
• When using the INCRA Miter V120,
always keep your hands clear of
the cutter and the line of cut.
• Always turn off the power and
make sure that the cutter comes
to a complete stop before
changing the setting of any part
of the INCRA Miter V120.
• Always securely tighten the large
black clamping knob before
starting any cut.
• Wear safety glasses, hearing pro-
tection, and follow all normal
shop safety practices.
• After making any adjustments to
the miter angle of your INCRA
Miter V120, always verify safe
clearance between the cutter and
all parts of the INCRA Miter V120,
and its attachments.
Setup
1
Using the supplied 3/32” hex key, adjust each of the (3) visible miter bar
expansion disks for a zero-sideplay, sliding fit in your Miter Channel as
shown in
Figure 2. Turning the
fastener clockwise EXPANDS the
bar width. The disks are designed
to require a fair amount of
adjustment torque for proper
expansion.

Remove the large clamping knob and disengage the indexing tooth from
the protractor. Pivot the protractor head to access and adjust the fourth
expansion point. See
Figure 3. Replace the large clamping knob and washer.

Square Miter Faceplate to your Application
(table saw, router table, etc.)
Caution: Always unplug the power tool before squaring the faceplate
to your application. Loosen both the large and the small clamping knobs.
Set the indexing tooth to 0 degrees, and tighten the small clamping knob,
then tighten the large clamping knob. See
Figure 4.

Using the supplied 1/8” hex key, loosen the (4) button head fasteners
that secure the faceplate to the protractor and, depending on your applica-
tion, square the faceplate to the blade, miter slot, sanding belt, etc.
NOTE:
When squaring to a saw blade (see Figure 5), use a reliable square for this
important alignment. Securely retighten the (4) button head fasteners to
complete the alignment.
This important one-time adjust-
ment prepares your INCRA Miter
V120 for perfect angles at all other
indexing tooth positions. Verify
the accuracy of your alignment
with a test cut, and re-align if the
cut is not exactly 90 degrees.
Fine adjustments to the angle of
the fence mounting bracket to
your table top can also be made by loosening the same fasteners and plac-
ing a paper shim between the bracket and the underside of the protractor.

Your INCRA Miter V120 is now ready to easily and accurately produce
perfect angles. Just loosen both clamping knobs and engage the indexing
tooth at the desired angle. Lock the indexing tooth clamping knob (the
small knob), then lock the large clamping knob.
Operation
Your INCRA Miter V120’s vertical faceplate doubles as a Universal Mounting
Bracket that makes it easy to attach your own user-made auxiliary fence if
you ever need one. Just cut a straight piece of wood to the desired length
(18” to 24” is a good size),
and attach with user-supplied
wood screws and washers through
the two slotted holes.
