Collets are a valuable piece of tooling for any lathe. With less run-out than a typical scroll chuck, they firmly grip the work without marring while being contained in a small, streamlined package. In this article I will describe constructing my first collet chuck which was machined from a single piece of bar stock. This chuck, which uses ER32 spring collets, will screw onto the spindle of the lathe in comparison to this lathe's native 6K collets which seat directly inside the spindle with a draw bar.
