Resin

For f’ks sake, the subject matter is: This article will hopefully help the custom rod builder better understand some of the characteristics of blanks, properties of the materials and the terms used to describe them. It doesn’t claim to be a treatise on casting But it is a thread on resin, I know. An...

Nobody expects the Big Spring Inquisition. Fetch the comfy chair. I’m just bloody glad he didn’t mention Jehovah.

Hi Daniel I think if you read it in context, it was clear that Emory Harry was introducing the concept of strain energy and not describing the total mechanics of a cast: Strain Energy There is another way of looking at the area under the modulus of elasticity curve is called Strain Energy. Strain En...

Preload? Thanks to provide me with Server’s paper on this point, I’m curious to read that. If it exists, it is not something common in casting and this introduces a doubt on the understanding of the author. For him, preload is something usual then? Hi Daniel I understand that Server lectures in Mec...

Hi Vince I refer to the sentence quoted by Paul, and I read something on the way energy is built during casting. I agree with Paul on the fact that we do not load the rod during the backcast to get the energy back in the forward cast. This is a kind of big spring approach and there is no conspiracy...

The big spring seems to be back :upside: Apart from this point the article is nearly OK, there are a few misconception (e.g. efficiency), but who cares? Merlin I think you are seeing conspiracy theories everywhere. :ninja: It’s a paragraph entitled strain energy and explains that when a material be...

When we cast a rod we are storing energy in the rod on the back cast and the first portion of the forward cast and then that energy is released on the latter portion of the forward cast by the rod.
Blimey! I didn’t expect to read this. :upside:
Why not ?

Many years ago when I was first interested in producing the HT one of the companies I visited was David Norwich. I had a very interesting day with David showing me how rods were manufactured. His carbon cloth came from Japan and was kept in the freezer. I assume this is the same for all companies. ...

I've been following this thread and I don't get a feeling you're getting a good answer to your question about the 'modulus'. In composites, a designer usually strives to get 'strain-compatibility' between the binder and the reinforcement. The 'modulus', here it's about tensile and/or flexural modul...

Stiffness and Tip speed

The difference in feel is fairly trivial, less than picking up a different rod. Distance was a bit shorter but only a couple of feet, not enough to make a difference for river trout fishing. It’s quite tip heavy and clunky but I was chucking about 85’ with it. It’s a Shakey Agility Exp that says 8.5...
