A typical segmented project will cost a lot less to make (even if you use exotic woods) because you make your blank in the shape of the project. This means a lot less material is needed.

There's less mess to clean up after turning a segmented object. Because you don't start with a solid chunk of wood, there will be 65-75% fewer shavings to clean up.

You can control the grain direction in segmented objects so the turning is easier with fewer opportunities for 'catches' and other unfortunate mishaps.

You'll end up with creations that Mother Nature could only dream of because, with segmented projects, you can mix different wood types and take advantage of different orientations of the joints between pieces of wood.

You can (in fact you'll have to) figure out what your segmented project will look like before you start. There are several design tools you can use to do this.

Segmented projects are a way for you make good use of those little, left over pieces of wood; even pen blanks are sometimes useful.

There are a bunch of people ready and eager to help you. At least six books and as many web sites are devoted to segmented turning.

You don't have to wait forever for the wood to dry. Kiln dried materials are readily available.

Segmented turning requires more patience and planning. You can't just throw a log on the lathe.

Segmented turning requires more accuracy. Good rings require accurate, consistent miter cuts, and good gluing techniques (so you'll have really good joints).
