Mick and Emory: Guide spacing may seem like an art to some degree, but I'm a true believer in phyiscal modeling and I've modeled some complex problems that I'm certain exceed that of a fishing blank and these models were predictive and found highly accurate when actual tests were performed. I may be wrong, but I have the impression that when I mention the word "formula," some folks

Emory: I think I see now what you are referring to as "stiffness" and second derivate. I was analyzing spacing purely from total physical deflection path and first derivative that any blank would make on a horizontal jig table with a well defined chart in the background. But a more accurate analysis would take into effect the second derivate so it would better deal with extreme l

Emory: The rod curve itself from butt to tip has ever increasing slope under load, and hence is monotonic because the first derivative is always increasing in absolute value isn't it? That is, if I brace the blank at the butt and extend it horizontally out, then dangle a weight at the tip, the slope of rod deflection is always getting steeper as I go toward the tip. That is the definition of

Hi folks. I couldn't help but get interested in this topic of spacing. I agree with Jim Benenson's assertion that if we assume natural curvature to be mathematically smooth and monotonically increasing in first derivative (in absolute value), then the spacings should increase not a fixed amount between guides, but a varied amount that continues to increase. But I'd argue further that as a fi

Hi Tom: First post on this board. I have some background fishing buzzbombs both from shore and from boat and have built a few rods for that purpose. To get an idea of what a buzz bomb is, check out the www.buzzbombzzinger.com website. Basically, as others have alluded to, it's a long diamond metal spoon designed to slide onto your main line through its center much like an egg sinker. The
