A Retractor can be used for two activities on the rose engine lathe.
- Fading work. But, unlike a fixed fading mechanism (e.g., the MDF rose engine's fading wedge), a retractor can be used to change the fading during the cut.
- Fixed Tool Turning, where the desire is to slowly engage the cutter into the work.

How it works
A typical retractor is a screw mechanism which is rotated using some form of mechanical attachment to the spindle. A common approach is to use a belt drive so that, as the spindle rotates, it also drives the action of the retractor to turn the screw.
