The Sherline Metric Lathe Crosslide Anti-Backlash Upgrade Kit is designed to enhance the precision of earlier Sherline lathes by retrofitting them with a backlash adjustment feature. This upgrade mirrors the effective design used on the mill X- and Y-axes, incorporating a round, knurled brass lock nut on the leadscrew. This component is tightened against the side of the saddle, effectively reducing excess play in the threads by pulling against the threads in the slide screw insert, thereby allowing for precise backlash adjustment.
Once the desired backlash is set, a knurled lock wheel, secured by a button head screw, ensures the lock nut remains in position, preventing any unintended movement. The kit also includes a drill guide block, which assists in accurately locating the hole that must be drilled and tapped into the lathe saddle, facilitating a seamless installation process.
