Assembly
Ball Handles
The ball handles for the X-axis leadscrew have
spring-loaded, keyed center bushings, as shown
in Figure 8. This allows them to disengage
from the leadscrew when using the power feed,
avoiding an entanglement hazard.
To install the ball handles:
1. Remove the hex nuts from each end of the
X-axis leadscrew.
2. Identify the two ball handles with the
spring-loaded center bushings (see
Figure 8).
3. For each ball handle, position it so that the
protruding part of the center bushing is
facing toward the table, align the keyway
with the leadscrew key, then slide it onto the
X-axis leadscrew.
4. Secure the ball handles with the hex nuts
removed in Step 1.
Note: Tighten the hex nuts just until they are
snug. Overtightening could increase the
wear of the moving parts.

6. Align the keyway of the ball handle with
leadscrew key, slide the Y-axis ball handle
(see Figure 8) onto the leadscrew, then
secure it in place with the removed hex nut.
7. Thread the handles into the small end of
the ball handles and tighten them with a
wrench.
