The leveling or truing chuck is the traditional way of compensating for uneven materials or inaccuracies in work holding systems when moving from machine to machine.
The chuck not only compensates for inaccuracies radially like a four jaw chuck, but it also allows for adjustments axially which are virtually impossible to deal with otherwise.
This tool is an absolute must for anyone turning layers or large diameter pieces where runout becomes pronounced because of the size. Both the male and female threads are 1″-8.
