How to Use This Calculator
- Enter the bar length (inches) — the total length of the section to be twisted.
- Set the desired turns per inch — more turns create tighter, denser patterns.
- Select bar cross-section: square, round, or rectangular.
- Review Total Turns, Heats Required, and Turns per Heat Zone to plan your twisting session.
- Account for Estimated Stretch (%) by leaving extra length before twisting to reach your final dimension.
