customers will attempt with it. After several months of
feedback, we noticed several areas where customers had
suggested a need for greater clearance or capacity. Some
users noted that lowering the column all the way down

by allowing the column saddle to be lowered an additional

Thecolumnsaddlelockupgradeprovidesasuperiormethod
of preventing saddle movement by locking the saddle nut
against the leadscrew. This is much more positive than the
existing friction saddle lock. We have looked for a way to
produce this for years, but it required finding a way to start
a thread in exactly the same place each time so that the

Disadvantages to lowering the saddle and how to
overcome them
Lowering the saddle makes it easier to work close to the
table.Thetrade-offthatalwaysoccurswithanyengineering
compromise is that movement at the top of the travel is
limited by the same amount as is gained at the bottom.
Certain tall setups that involve multiple accessories can
stack up to a height that may require more clearance at the
top end. You will probably find that with the upgrade in
