I'll show you how make round wooden bowls from strips of wood and a bandsaw. I don't have a wood lathe, so I found a way to create round bowls using my bandsaw. You can make them any diameter 3 inches and up. The pictures show a few of the bowls I made from mesquite wood. My instructions will get you between 4 to 6 nesting bowls from one setup.
This method also allows you to make very large bowls that would be impossible to do on your typical lathe.
People's reaction is typically "How do you make these?" and "Do you sell these?". I'll show you how I make them; but no, I do not sell the bowls: I just make them for relatives and friends.
