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.
