Helix Builder™ — Digital Helix Design & Build Package

Helix Builder™ is a comprehensive, build-ready system that helps you plan your helix and fabricate it with confidence. Unlike basic helix calculators that stop at grade math, Helix Builder™ produces practical outputs you can build from—backed by clear shop drawings and guidance pages.

What’s Included

• Helix Builder™ (browser-based tool)
• Imperial / Metric toggle
• Cut list generated from your inputs
• 16-page Shop drawing package with dimensions, drilling locations, and assembly photo references
• 22 Introduction/informational pages with photo references to help you select a configuration and build accurately
• 9-page Assembly instructions

Key Features

• Total Rise output (overall helix height)
• Total Run output (total track length estimate)
• Maximum Clearance output (verify equipment clearance; subtract rail height as needed)
• Supports fractional turns (in 1/12-turn steps) to match real entry/exit positions
• Supports multiple helix styles (circular, elongated/oval, and advanced configurations)

Who This Is For

• Builders who want to DIY a helix from plywood with accurate parts and proven drawings
• Anyone trying to reduce re-cuts, guesswork, and “almost fits” assemblies
• Modelers who want to estimate track length, footprint, and clearance before committing

How It Works

1. Enter your design inputs (radius, roadbed width, grade target, rise per turn, turns, segment count, etc.).
2. Review outputs (rise, run, clearance, inside/outside dimensions).
3. Cut parts using the generated cut list and build using the included shop drawings and references.
