Fly rod guide spacing calculator

This page uses the sums laid out in Art Scheck's excellent book "Fly Rod Building Made Easy: A Complete Step-by-step Guide to Making a High-quality Fly Rod on a Budget"  (ISBN-13: 978-0881505115). Any errors are mine, not his.

The first/last guide positions and the ferrule length (actually the insertion length) should be entered as decimals ("3.75" etc.); the output can be converted to any of the units in the drop-down box. If any of the guide positions is calculated to be within one and a half inches of a joint, that guide will be marked with a warning.
