Dave asked if I did Corian rings and so I did three black corian rings in 3 different sizes. I also turned 3 pendants in CMU ( Central Michigan) colors. I was cutting some purple heart and Osage orange and I dumped the chips together and they looked so close to the CMU colors that I had to laminate the two woods together and these pendants came out of it. All these pieces are finished with EEE and Shellawax.
I was asked to show the expanding mandrels I use to make rings so I have a series of process shots of how I made the corian rings:
If I start with flat stock, I drill holes so they can be mounted on a bolt and rounded up on the metal lathe or the wood lathe. I use the metal lathe for these.
I turned them round to a little over the finished size.
Then I bore them to the ring size.
These are the 7 mandrels and the 3/4”nylon adapter that fits the wood lathe chuck
Then I mount the ring on the mandrel and expand it by tightening the screw. If the ring is weak, it usually breaks at this stage.
Then I turn and finish the ring -flipping is from side to side in the process
Here are some close up shots of the mandrel and the adapter
