Model G0757Z (Mfd. Since 02/15)
Installing Horizontal Spindle &
Tooling
Single or multiple cutters (gang milling) can be
arranged anywhere along the length of the arbor
for simple to very complex cutting operations.
4. With one hand holding tooling in place, insert
vertical drawbar (longer of two drawbars) into
spindle from top of head, then thread it into
tooling (see Figure 27).
Note: Drawbar has an adjustment hex nut
(see Figure 27) that is used to raise/lower
drawbar to compensate for different tooling
lengths.
5. Tighten drawbar until it is snug. Avoid over-
tightening, as this could make removing tool-
ing difficult later.

Note: Make sure drawbar has at least three
threads engaged with tooling in next step to
avoid damaging drawbar threads or tool.
2. Loosen drawbar a couple of turns, then tap
top of it with a brass hammer to knock taper
between spindle and tooling loose.
3. Support tooling with one hand, then com-
pletely unthread drawbar from tooling.
