3. When the auto feed and the clamping bracket are secured together, set the assembly on the
end of the table, so the gears mesh. The clamping bracket will fit over the top of the table, allow-
ing the bolts on the inboard side of the bracket to be tightened against the table’s cast iron sur-
face. Mark the point on the table’s trough where the mounting bolts contact the table and spot
drill to give the mounting bolts a surface to “bite” without slipping on the rough cast surface.

4. Replace the center travel stop at the front of the table with the microswitch. The switch, when
used with the adjustable stops, automatically limits table movement.
Caution: Before operating the Model G1126, make sure the placement of the auto feed’s power
cord and the control cord for the microswitch are both clear of any movements which could pinch or
crush either cord. Before operating the power feed, mark the maximum distance the table can move
before the power feed comes in contact with the machine’s base. Use that as a reference mark each
time you re-adjust your table stops to avoid possible damage to the power feed.
NOTE: Use care when aligning the leadscrew gears with the gearing on the power feeder. The fit is
correct when you can just slightly wiggle one gear without moving the other. If there is too much
space between the gears, teeth can be stripped under heavy loads. If the teeth mesh too tightly, the
supporting bearings in the power feeder will wear out prematurely.
An alternative method for attaching the power feed is to eliminate the clamping bracket and mount
the power feed directly to the table. As with the other method, you want to be certain that the gears
are properly aligned. Once aligned, mark, drill and tap holes in the end of the table casting. Bolt the
power feed to the casting.
In many ways, this method of attachment is much better than the other method. The removal of the
clamping bracket provides more secure mounting and provides a greater area of flat table space.
