C3 Mini Lathe Bearing Change

A step by step guide to replacing the single row ball bearings fitted to the headstock on the SIEG C3 and similar Mini Lathes with 30206 taper roller bearings. Proper replacement will provide a higher precision finish on your work and reduce or eliminate tool chatter.

This project requires the use of a second lathe to make and adjust two plastic spacers in the gearbox so don't start work if you don't have the facilities!
