i thought a steady rest is for this kinda thing.

[johnrob281]

@Guds777 -- You're right! I think today we would use the steady reat for the same thing. This tool was popular with the electric motor repair folks. For some reason they did not use a steady rest. ---John---

THE BRASS WILL WARE ALOT?

[johnrob281]

@djzupzup You are correct, the brass will wear. However the speeds are relatively slow and the brass is softer than the shaft. Replacing the brass inserts (after years of use) is much easier and less expensive than replacing a motor shaft or armature shaft..
