Sorry about that post Did some more reading on it No way to shorten the process got to meassure with pennies count and then calculate

Bill - willierods.com

Read the article. It explains the standards used to fix the blank into a shape that the designer defines as "fully loaded." That amount of weight in a static environment is not the same amount of weight the blank is able to cast. Please read the article.

Hmmm...I detect the rich aroma of politicians.

Tell you what - load the blank with the amount of weight required to flex it to a distance equal to 1/3rd of it's length. Now go outside and attempt to cast that amount of weight with it. The sound you hear will be the blank exploding.

The blank isn't measured for the amount of weight it will cast - it is loaded to a specific point and then measured for relative power.

Tom, I think given the context that's one of the funnier things you've posted. /smile

Bill,
Even with a small amount of weight hanging from the end of a rod, barely deflecting it in a static (unmoving) mode, if enough energy and speed was applied, the rod could be flexed beyond its safe design limits. Designers/engineers can calculate for stress loads, but the amount of input energy/speed can only be estimated to be within a range derived from averaged angler’s capabilities (the “human factor”). Formulas can be generated, but along with known variable properties, unknown subjective variables (“human factor”) would also have to be “guesstimated” and included so as to derive a “suggested lure weight range”. The calculation would/should be within the “safe limits” of the rod’s capacity, but again, if enough energy and speed was applied, exceeding the human factor assumption, it could result in failure.

Jim,

That was a nice added touch to the topic at hand. It explains the added energy from a moving object is greater than it is at rest.

If an object that weighs 640 times less than a products breaking strength, can break that product, (a half ounce lure snapping 20# test line), as the result of too rapid of an acceleration, or deceleration, I see no reason that the same wouldn't apply to a rod blank. Like Tom said .... get ready to hear a loud crack. And hopefully you have a firm grip on the rod's handle, or that baby may go in the water.
