Gap Insert Removal
& Installation
this lathe is equipped with a removable gap
insert that will allow for turning large diameter
workpieces. the gap was seated, pre-loaded,
and then ground for precise mating and alignment
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.
