INSTRUCTION SHEET
MODEL G1760
DIVIDING PLATES
The Model G1760 Dividing Plates are designed for
the Model G1049 6" Rotary Table. Dividing plates can
be installed onto the G1049 6" Rotary Table to achieve
a higher precision of hole placement, spot facing and
gear making.
3. Insert the dividing plate with the counter
bores facing out and secure it with the
provided screw.
4. Place the sector arm assembly over the
shaft, then slide the sector spring into the slot
on the shaft to secure the assembly.
5. Install the crank handle with the indexing pin
and secure it with the cap screw.

1. Remove the crank handle cap screw shown
in Figure 2.
2. Gently tap the crank handle off the shaft with
a rubber mallet and tape the key to the
handwheel for safe keeping.

The Model G1760 has three plates with the
following hole circles:
Plate A: 15, 16, 17, 18, 19, 20.
Plate B: 21, 23, 27, 29, 31, 33.
Plate C: 37, 39, 41, 43, 47, 49.
Basic Example:
You are making a bolt pattern that has a 13 hole
bolt pattern.
Crank turns =
90
⁄N
N = the desired division number (13).
90
⁄13 = 612⁄13
1. Look up 13 in the spacing column on the
index table to find the correct hole divisions.
Turns: 6
Holes: 36
Hole Circle: 39
2. Install the “C” dividing plate onto the rotary
table as described earlier, set the crank
handle and the indexing pin to index the 39
hole circle.
3. Turn the handwheel before making the first
hole to take up any play in the worm gears. It
is important to always turn the handle the
same way.
4. Set the sector arms so there are 36 holes
plus the hole the indexing pin is located in,
then tighten the screw.
5. Make your first hole, then turn the crank 6 full
turns and move 36 holes on the 39 hole
index plate to rotate exactly
12
⁄13 of a turn. The
6
12
⁄13 revolutions are equal to the sector arm
adjustment that was done in step 4.
6. Rotate the sector arm so that the arm locates
on the pin once again, then crank the handle
until the pin will drop into the last hole
between the sector arms.
7. Repeat step 6 for the remaining holes.
