Welcome to the activity to eat up time - Turning is a good thing though --
Segment construciton is a pretty broad topic with different approaches to different styles. the scroll saw artists use different gear and jigs than do the compound miter saw (CMS) crowd, and then there are the different kinds and sizes of table saws - and the different approaches to disk sanders.
I suggest you tour the library to see what others have written up, and then browse through the photos --- and do tell us what your gear (or your dreams of gear) might be and how you want to approch the opportunity --
Take a good look at the celtic knot style of segmentation as well as some of the scroll saws work -- Lots of ideas around for you to look over.
Again Welcome
