Typically, when creating a wooden bowl a crafts person would do so on a lathe. A chunk of wood would be bolted to the head stock and the bottom of the bowl turned to an appropriate shape. Then the half-bowl-shaped wood is flipped around on the lathe so that the material on the inside of the bowl can be removed. This traditional method of bowl turning requires a lathe, turning tools, and the serious technique and skill required for the task.
The master maker of weird wood working tools, [Izzy], decided to make a wooden bowl without the use of a lathe. He created a unique fixture to cut the shape of the bowl on a table saw, a piece of equipment that is a bit more common for the average DIYer to have. The fixture itself is made of wood and supports a standard hand drill in a vertical position. The soon-to-be bowl is bolted to the drill and hovers just above the table saw blade. The table saw is turned on and the fixture allows the work piece to rock back and forth creating the bowls outside shape. The drill rotates the piece so that the contours are consistent around the bowl.
The bowl is then flipped over and re-attached to the drill. This time to cut the inside of the bowl, the fixture is locked in the vertical position and the wood is dropped straight down on the spinning blade while being rotated. The saw blade cuts a perfectly hemispherical cavity in the wood. The final bowl looks great after a little sanding and an application of oil. Check out the video after the break.
