Product Description

Coming December 2023

New from Planet A British made Chuck Mandrel for turning wooden or composite rings complete with 3 sets of bushings for the most common range of ring sizes.  Available in the three most common thread sizes M33x3.5mm, 3/4x16tpi or 1x8tpi.  

The Ring Turning Chuck provides precision and convenience when turning ring cores helping you to achieve a perfect high quality finish on your rings. The chuck can also be used with other small projects.

The chuck is screwed directly onto your lathe spindle. It can be removed using a knockout bar (in the hole), or a spanner.

When you look at the tool in detail, you'll see that it's precision machined from solid steel and threaded to fit directly onto your lathes spindle, the single piece design with 60 degree dimple on the end of the shaft for tailstock support guarantees perfect concentricity every time.

Benefits of a chuck over expanding mandrels

  • The artisan ring turning chuck, being attached directly to the spindle of the lathe, prevents concentricity issues that might occur when expanding ring mandrels are inserted into a chuck (prevents "wobble").
  • Only one chuck is required rather than at least two expanding ring mandrels giving great value for money.
  • No moving parts, providing the chuck with a longer lifespan than mandrels or step chucks.

Ring Turning Bushing size

Long-lasting machined aluminum ring bushings are included in small, medium and large sizes. The ring making bushings allow you to turn a full range of ring sizes from 4-16 (USA) including half sizes.

With the Ring Turning Chuck, changing bushings and mounting ring cores is as easy as removing the brass tightening nut, swapping out bushings and replacing the nut. This will be the most used ring making tool in your work-shop.

  • Designed & manufactured specifically for turning ring cores
  • Machined from solid steel, one-piece design
  • 60 degree shaft recess for revolving cone center support
  • Accurate & and eliminates vibration
  • Changing bushings is quick and easy
  • Wrench flats for easy removal - (wrench not included)
  • Made in England

Package includes:

  • Ring chuck body
  • Set of small aluminium ring bushings
  • Set of medium aluminium ring bushings
  • Set of large aluminium ring bushings

The 3 bushings fit ring sizes 3-16 (USA) & F-Z+7 (UK) - Some ring sizes can be used on 2 different size bushings, this allows flexibility on how the ring is presented on the chuck.


When applying a finish such as CA glue to the ring, we recommend that you cover the bushings with a suitable protective tape. You'll get first class work and the bushings will have a longer lifespan.
