To install your Model G1049 onto your mill
table:
1. Disconnect power to the milling machine
before installing the rotary table.
2.Position the 1/2" T-bolt slots on the rotary
table over the T-slots in the milling table.
3. Insert the T-slot nuts into the milling table
grooves.
4. Secure the rotary table in place. It is impor-
tant to secure the rotary table to the mill table
in a very strong and solid set up. This will
help with accuracy, efficiency and general
safety.
Note— The T-slots for the rotary table are 2"
between centers. You will need to have the
same distance between centers on your
milling table to be able to use T-nuts and
bolts. If your milling table has different T-slot
centers, you will need to incorporate step
blocks or clamps to secure the rotary table.
Installation
Make sure the rotary table is secured to
the milling table. Check the T-slot clamps
before each cutting operation. If rotary
table is not secured, serious personal
injury and damage to your mill and rotary
table could result.
Before installing the Model G1049 6"
Combination Rotary Table, make sure that your
mill table and spindle are aligned correctly as
described in your milling machine instruction
manual.
NOTICE
Make sure the rotary table handle is free of
any obstruction. Depending on your setup
in the vertical or horizontal positions, the
rotary table may have to be blocked up or
mounted so the handle is hanging over the
edge of the milling table. Once making a
setup, check for any possible obstructions
that may interfere with rotary table handle.

-6- G1049 6" Combination Rotary Table
Aligning the center of the rotary table to the spin-
dle is essential for achieving quality results.
There are many ways to align the Model G1049
to a vertical mill spindle. It is up to the machinist
and his capabilities to decide which approach is
best.
Here are a couple of ways to align the spindle
accurately to the center of the rotary table:
1. Using a test indicator, (see Models G9610,
G9611 & G9612 in the current Grizzly cata-
log) indicate the inside or the outside of the
rotary table. Position the spindle over center
of the rotary table and touch all four sides
(inside or outside) until all sides read “0” on
the indicator (remember to rotate the spindle
and not the rotary table). Using this proce-
dure of indicating, no measuring tools are
needed.
Alignment
Figure 2. Locations for edge finding.
2. Use an edge finder, like the Model H2939, to
locate the center of the rotary table by con-
tacting two outside edges (Figure 2) and
then moving the mill table half of the rotary
table diameter in both directions. Note—
Make sure to account for radius of the edge
finder and use a precision measuring instru-
ment when determining the diameter of the
rotary table.
Wear safety glasses dur-
ing the entire setup
process!

Table Movement
Operation Safety
SECTION 4: OPERATIONS
The rotary table moves by turning the handwheel
which engages a precision worm gear. The worm
gear ratio is 1:90. One complete turn of the hand-
wheel moves the table 4 degrees. The micro col-
lar is graduated in steps of 1 minute and the
vernier scale can be set to indicate to 20 sec-
onds.
Basic Example:
You are making a flange and you need to index
six holes for the bolt pattern:
Crank turns = 90⁄N
N = the desired division number (6).
90/6= 15 full crank turns
1. Turn the handwheel before making the first
hole to take up any play in the worm gears.
2. Make your first hole then turn the crank 15
times. Note—When you are cranking to a
desired number and crank too far, do not just
immediately back up to the number. You
must back up one revolution then dial back to
desired number, Then lock the table in place
to locate the second hole. This procedure
eliminates backlash in the worm gear.
3. Repeat step 2 for the remaining holes.
Damage to your eyes, lungs, and ears could
result from failure to wear safety glasses, a
respirator and hearing protection while
using this equipment. Make sure proper fil-
ter is worn while wearing respirator.
Rotary Table
Maintenance
Keep oiled to prevent rust. Do not use air to blow
off chips. A few drops of oil before each use will
prevent excessive wear. The worm gear is
greased at the factory.

-8- G1049 6" Combination Rotary Table
1. MT#2—Used for quick setups by placing a
dead center into the taper and aligning cen-
ters, picking up hole centers, ect and just
general machining operations.
2. Rotary Table Lock—Used during milling
operations to lock the table solid. This fea-
ture keeps the stresses of the milling opera-
tions off of the wormgear to extend the life of
the rotary table and ensure that accuracy is
not compromised. Simply tighten the handles
to lock the table.
3. Free Wheeling—This is a convience feature
which allows the operator to rotate the table
by hand and not having to turn the crank
handle. just loosen the lock handle (#3) and
rotate the adjustment ring (#6) C.W. By rotat-
ing the adjustment ring, this disengages the
wormgear and allows the table to rotate.
4. Vernier Scale—Allows precise rotary move-
ments. The vernier scale allows graduations
of 20" seconds.
5. Gross Scale—This scale will allow you
keep track of where the rotary table is going
and where its been. The scale reads from 0˚-
360˚ in one degree graduations.
