-  *Travelling steady\\ +The Metal Lathe is very happy cutting most common engineering materials. including: 
-  *Fixed steady\\ +  * Ferrous metals: Steel, cast iron and stainless steel  
-  *Rotating centre for Tailstock\\ +  * Non-Ferrous metals: Brass and Aluminium. 
-  *Keyless Chuck for Tailstock \\ +  * Engineering plastics: Such as Nylon, Delrin, Acetyl are also perfect.

-  +On very rare occasions, when there is a case for using metal lathe to cut hard wood precisely. If this is the case, please take care clean off all traces of wood dust when you have finished. After clean up, anoint the lathe with copious amounts of ways oil, repent for your sins and consider sacrificing a small mammal to the metal gods.
