CaneCalc
Taper design, stress analysis, and casting simulation
for bamboo rod makers.
Real-time engineering that runs entirely in your browser.
Open the Design ToolReal-time stress analysis
Garrison stress analysis recalculates as you edit. Change a dimension and see the stress curve respond on the next frame. No waiting, no refresh — the curve is always current.
The 220,000 psi threshold line shows where bamboo fibers are at risk. Shape your taper to keep stress below the limit across every station.

Compare any two tapers
Overlay a Garrison against a Dickerson. See where stress profiles diverge and why one taper casts differently from another. The comparison curve appears as a dashed line so the primary taper stays in focus.
Load any taper from the community library as a reference — Payne, Young, Leonard, Carmichael, or your own.

Marinaro Chart Improvements
ImprovedCommunity FeedbackMarinaro chart now defaults to 1x Y-axis exaggeration with section slopes visible by default. Slope rates display in thou/in to match Hexrod conventions. Section slope lines are brighter and more visible, with smaller station dots so subtle convexity is easier to read. Butt slope rate now extends through grip stations, matching Hexrod behavior.
Chart Zoom Controls
NewDrag to zoom into any region of any chart. A Reset button appears in the toolbar when zoomed, and double-click anywhere to snap back to the full view. Works on all chart types — stress, dimensions, Bokstrom, deflection, Marinaro, and more.
Design Title Sync
FixedRenaming a design in the save dialog now updates the title inside the taper data. Previously, reopening a renamed design would show the old title.
