Home of Hexrod Cane Rod System

Hexrod is a set of tools for split cane fly rod tapers.

The core of Hexrod is the engineering stress analysis developed by Everett Garrison and described in his book, A Master's Guide to Building a Bamboo Fly Rod, Everett Garrison and Hoagy B. Carmichael, first published in 1977. Wayne Cattanach implemented the analysis in the BASIC language and named it Hexrod, and this online version is started as a translation of Wayne's code into CGI/Perl by this author. I made it available beginning in 1997 on the personal webpage server at the University of Wisconsin-Milwaukee.

Like many computer programs, Hexrod grew by "creeping featurism." Many cane enthusiasts submitted ideas for improvements and important information for inclusion. In particular, Claude Freaner worked out the stress formulas for penta and quad construction, which permitted conversion between rod geometries. Later, tools for John Bokstrom's method of controlled modification of tapers were added. And the taper graphs developed by Vince Marinaro and described in the "Split and Glued" book by Whittle and Harms. In 2020, various deflection calculations were added.

It also performs more mundane chores like calculating ferrule sizes and planing form settings. See the documentation page for some details.

I've tried to make Hexrod simple to use; anyone who knows how to construct a split cane fly rod should be able to get the hang of it in a few minutes.
