gap removal
A section of the bed called the "gap" is located
just under the spindle and can be removed for
turning large diameter parts or when using a large
diameter faceplate.
the gap is installed, then ground, at the factory
during lathe assembly for precise fit and align-
ment. Factors during the remaining assembly
apply additional forces to the gap; therefore,
replacing the gap to the original position will be
very difficult.
if you choose to remove the gap,
the mating surfaces of the gap will probably
not sit flush with the bed if you ever re-install
it. for that reason, removing the gap is consid-
ered a permanent alteration to the machine.
