People who love to craft designs from wood have made amazing art using this particular woodworking method. Some of patterns are quite spectacular and your project can be, too! Among the many masterpieces that I’ve seen online, my all-time favorite is a segmented bowl. The one that I saw was really beautiful and way the pattern spiraled into the bottom of the bowl gave it great depth. One day soon, I plan on making one for my own home.
You can start by deciding on the general shape and size of your project and the appearance of your final work. You also need to consider the color and design pattern you want. Consider the species of wood to use to contrast the different colors and final appearance.
The best way and most cost efficient way to make one of these bowl is to create a block of wood gluing strips of wood together of different thickness and colors. If you repeat the design on each side of the center you will have spiral design on each side to the bowl. The block should be between 2.5 inches and 3 inches thick when finished. You will then cut boards from the block you just glued up, you need four boards, and thickness is variable. You will need to need to cut rings from these boards. Use a compass to draw the rings so that they should nest inside one another. The rings can be cut out with a scroll saw or a band saw; if you use a band saw do not glue the center of the block; you can tape the boards together to draw the rings. The rings can be glued together later.
From large to small, each ring is slightly larger than the previous ring. It is critical that the surface of the rings be smooth and well sanded, any blemish will be highly visible in your finished work. The rings overlap each other by a half inch to three quarter inches, when gluing these rings together it is important that the rings be centered within each other and the stack as vertical as possible. The side walls of the finished bowl will be thin 1/4 to 3/8 inches, if there is excessive wobble or the stack is not vertical you will cut through one side and a lot of work will be wasted.
The stack of rings will not be perfect, but should be glued together as carefully as possible. Rotating the rings as you glue them together will create the spiral design.
