Thanks to each who commented on my last post. There were a lot of great ideas. Many focused on using a band saw. For this video, I show changes to the original jig for the table saw plus some examples for cutting rings on the lathe and bandsaw.

Each approach has its own strengths and limitations.

Table saw:
Can handle large and small ring sizes.
Slight limitation due to segment width vs saw height.
Takes a wide kerf depending on saw blade.

Band saw:
Narrow saw kerf
Jig and saw capacity limit larger ring sizes.

Lathe
Capacity limitation is moot since the lathe capacity limits ring size anyway.
Requires some form of mounting

For some techniques, I paid a visit to Frank Young, who has been a guest previously on this channel.

Splitting on the lathe:
I demonstrate an unsupported cut risking the ring breaking.
Frank demonstrates cutting while the offset is held securely

Splitting on a bandsaw:
Frank demonstrates his jig for safely and accurately cutting on the band saw.

Splitting on a table saw.
I show updates to my jig for additional safety while cutting on the table saw.

Which technique is best? That depends on your equipment, your project, your skill level. Best of all is to have a variety of techniques available to choose from and to adapt to different circumstances.
