Segmented Screws
Vol.20 #3, Dec. 1993
When assembling a segmented screw, lapping the ends of the elements minimizes polymer leakage along the shaft.
It is common to have burrs develop at the flight tips that prevent close mating of the surfaces. Moving the element in a figure 8 pattern on 400 grit sandpaper on a smooth, flat surface will remove the burrs without causing any problem.
