About this calculator
Overview
Segmented woodturning involves gluing together many small pieces of wood (segments) to form a ring, then stacking those rings to create a bowl. This technique allows for complex patterns and large bowls from small boards.
💡
Pro Tips
Always cut a test segment first to verify your miter angle. A 0.1° error becomes a 1.2° gap on a 12-segment ring.
Use a 'Wedgie Sled' for your table saw to get perfectly matching angles every time.
Plane or sand the surfaces of the rings perfectly flat before gluing them together.

Fun Facts
"Segmented turning uses much less wood than turning a 'solid' bowl because you aren't hollowing out the center."
"The 'golden ratio' is often used by turners to decide the height and diameter of their rings for better aesthetics."
"A segmented bowl can have hundreds or even thousands of individual pieces of wood."
