Materials Used: wood (apple log, self-dried), beeswax
Tools Used: woodturning tools:
Approx. Cost: next to nothing


Turning "captive rings" is a tricky technique, but tried by many woodturners at some point.

I taught myself how to do it in order to make a one-piece rattle for some awesome babies!

tl;dr

  • hard wood
  • patience
  • shape & sand as much as you can before "freeing" the ring
  • expect some burn marks

Choosing the Material

You'll need especially even-grained and dense wood for this project or the rings are prone to breaking.

I was very happy with the apple log I had laid aside for this project all along, but the birch and especially fir that I used as first tests behaved pretty badly.


Making the Hook Tool

First of all, I made the special tool needed to undercut the rings. There are commercial "ring" or "hook" tools available but I had seen DIY versions made from hex keys and obviously just had to try that!

Materials:

Educative Failures

lessons learned: wood too soft, piece too thin


lessons learned: wood still a bit too soft, parting tool much more suitable to define the ring width than spindle gouge, poor bevel on the hook tool, use even less force than usual


The second birch ring turned out a lot better than the first so I decided to get serious!
