The gap insert directly under the spindle (see 
Figure 138) can be removed to create additional 
space for turning large diameter parts.
The gap insert was installed, then ground flush 
with the bed at the factory to ensure a precision 
fit and alignment. Therefore, if the gap insert is 
removed, it may be difficult to re-install with the 
same degree of accuracy.
