Decorative cups and bowls can be made on a woodturning lathe, and are often made out of a single block of wood (or a straightforward laminated block of wood). For a more complex appearance, try a segmented wood turning. In a segmented turning, the turning blank is made out of a series of stacked wooden rings. Each of these rings is made from a group of small, precisely cut pieces of wood often of different wood species. Each piece must be cut at an exact angle, or the resulting ring will have small gaps between adjacent pieces. This is challenging enough that people make or buy special jigs for cutting these pieces very accurately.
This instructable shows an alternative way to make these rings which greatly simplifies the cutting and assembly of the pieces. Using a laser cutter, each piece is created to resemble a jigsaw piece. This not only provides the precise angle needed between pieces, but eliminates the need to clamp the pieces when gluing them together to create each ring.
This instructable shows how to make the segmented turning blank itself, but not the process of turning it on a lathe to make the final piece. That is a likely topic for a future instructable...
