What other materials can a lathe be made of?
I said all that to explain the importance of the material you will use to make a lathe, if the lathe will be used for small, light and easy to cut materials you can make it from Wood, (seasoned hard wood) precision ground steel tubes, extruded aluminum, remember, the larger and heavier the turnings, the more rigid the materials are for building the lathe, accuracy and tolerances in building the lathe “Equals” more accuracy an ease of turning.
