Turning Segmented Wood: Making Beads-of-Courage Vessels

Every year the Beads-of-Courage (http://www.beadsofcourage.org/) program provides 60,000 sick children in 250 hospitals beads for every procedure they have to endure. They start out stringing these beads together but too often they have so many that they need a container to hold them all. The organization asks woodworkers create fancy boxes to hold beads. In March I made a vessel using flat boards.

My First Beads of Courage Vessel With Rings Made Out of Two Flat Boards

I recently joined a group of woodworkers learning to make round objects using segments. The technique uses triangles or trapezoids glued together to form rings that are stacked to make bowls, vases, urns and similar cylindrical forms. By incorporating different colors of wood, these creations can be extraordinary. The pieces of wood are typically arranged so that grain is tangent to the circumference of these round forms. Tools then shave nice ribbons when slicing along the grain. When making a ring from a solid board, only two small parts cut along the grain the rest becomes more difficult as more and more wood fibers have to be cut at up to 90 degrees. Cutting tools often pull bits of fiber out of the wood that require more sandpaper and effort to finish.

Three additional vessels use twelve trapezoids that have 15 degree angles on each end to create five or six rings. The upper and lower rings of the cylinder are walnut and the three layers that make up the top alternate cherry, walnut and soft maple. The sides of the vessels utilize either soft maple or birch dowels, lined with clear formed polycarbonate sheet. Knobs (actually rejected wine stopper handles) were turned from lilac. In contrast to the first vessel that used two pieces of wood, the solid cylinders use 74 pieces, not counting knobs.
