NOTICE
Use care when aligning the table leadscrew
gears with the gearing on the power feed.
The fit is correct when you can just slightly
wiggle one gear without engaging 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 sup-
porting bearings in the power feeder will
wear out quickly.

3. Attach the power feed body to the clamping
bracket assembly with the hex bolts. Before
tightening completely, position the power feed
body so the gears mesh perfectly. Tighten the
hex bolts when the gears are in mesh (Figure
14).

The Model G1007 features a 110V auto-feed
mechanism which allows hands-free, side-to-side
passes while milling. Variable-speed feed control
makes flat surface milling more consistent.
To install the power feed:
1. Attach the 2 1 /
4
" diameter drive gear to the left
end of the longitudinal table leadscrew. The
gear couplers on the drive gear and table
leadscrew will lock together (Figure 12).

2. Set the clamping bracket assembly on the left
end of the table. Mark the points on the table
trough where the mounting bolts contact the
table. Remove the clamping bracket assem-
bly and spot drill to give the mounting bolts
a small lip to “bite” without slipping on the
rough cast surface. Set the clamping bracket
assembly back on the end of the table and
tighten down the mounting bolts (Figure 13).
