Gap Removal &
Installation
This lathe is equipped with a removable gap
insert that will allow for turning large diameter
workpieces. The gap was seated, preloaded, and
then ground for precise bedway mating and align-
ment at the factory.
Removing the gap can cause the lathe insert to
slightly spring out of shape. When re-installed,
there is no guarantee that original alignment and
flush mating will be the same. For this reason,
removing the gap is considered a permanent
alteration to the lathe, even if it is later re-installed.
