Description:
Pi Dividers are a precision measuring tool designed to quickly determine the circumference of standard sized glass tubing. The tool is constructed with two pointed legs joined at a pivot, allowing the user to set a consistent spacing and transfer that measurement directly onto the work. In lampworking and scientific glassblowing, Pi Dividers are used when you need to measure how much material is required to make a single wrap around a tube, such as planning a wrap-and-rake decoration, sizing a strap wrap, or laying out evenly spaced marks around the outside diameter of tubing.
How it is used:
- Set the divider points to match the outside diameter of the tubing you are working with.
- Step the dividers around the circumference to determine the wrap length needed for a single full rotation.
- Transfer the measurement to rod, stringer, or strip material so you can cut or pull the correct length before heating.
- Use the same setting to repeat consistent wraps across multiple pieces of the same tubing size.
