A lathe / l eɪ ð / is a tool that rotates the workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
One of the things that many builders find daunting about the idea of manufacturing firearms completely from scratch, is manufacturing a rifled barrel. There are two tough nuts to crack with barrel making. The first is deep hole drilling, which is still called in industry "gun drilling ...

Drilling: In drilling nickel alloys, steady feed rates should be used. If the drill is allowed to dwell, excessive work hardening of the metal at the bottom of the hole will make it difficult to resume cutting and may result in breaking of the drill when it does take hold.
