This RGWOOD 2MT 1″ Safety Drive with Spring Center will mount right into your 2MT lathe spindle for an easy switch to spindle turning. This drive center relies on friction on it's rim to hold your workpiece in place (much like a clutch in a manual transmission), but WILL spin on a catch. In addition, the spring loaded center makes this chuck spur easy to align and mount. What is a drive spur? A drive spur, also called a “drive center,” is a small, pointed piece that fits right into the spindle of your wood lathe, to securely hold your work-piece in preparation for turning. This is ideal particularly for spindle turning, and works by providing a central point of contact for the tailstock live center to push against. To use a drive spur, simply insert the spur into your lathe spindle, align your project's center with the spur, and then engage the tailstock live center to push against the work-piece and keep it stable while turning.
