SC3 Half Nut Conversion

SIEG Super C3 Mini-Lathe Half Nut Conversion Guide

A leadscrew cover helps to keep swarf out of the leadscrew threads but it also means only one half nut is fitted instead of two.

Some users prefer the traditional use of two half nuts to ensure greater accuracy and load capability. This conversion guide shows you how.

The guide applies to:

  • SIEG SC2
  • SIEG SC3
  • Those SIEG C2 Mini Lathes fitted with a leadscrew cover.
