Solid Octagon rods

Hi,
Have anyone seen and casted these:

Nope. I’ve tried solid tips before. And also
B&W Hexagraph, many years ago.

No opinions and I would need to test drive. The cork looks to be poor quality unfortunately and the rings look like they would cause friction problems.

I agree with them that it’s possible to go too light. But I don’t *think* I want to go heavier that I currently do. I don’t like FG as a material for complete rods and think Bamboo is the better material of the two. FG butt sections have some interesting possibilities.

Personally I don’t think the difference between rods is so much about materials. Obviously it plays a part, but really it’s about design and how it performs throughout the distance and speed ranges. I really find it hard to imagine anything better than what we currently have available nowadays, and quite what that would be I don’t know. Heavier I don’t think is it. A thinner blank diameter is interesting however and I can imagine advantages here. But not if the end result is rod bounce, which has been the problem with the solid carbon tips I’ve cast.

Interesting. Thanks for posting Grunde and I look forward to trying one when that happens.

Cheers, Paul

Cool to see someone thinking outside of the box.
Artfully done although at prices close to $3000.
Interestingly one site has some of the lower weight
blanks available for $450 which includes a
nice tube and sock.
Here is a video of the rod being cast. Again more art than substance but perhaps something can be gleaned from it by those with a practiced eye.

I'd love to have a cast with one for the sake of an "academic exercise" but I'm happy casting any rod.

Well obviously there are a couple of issues there. I suspect some of that might be caused by the weight in the tip. But how much is caster and how much is rod I don’t know.

I think you're being very diplomatic there Paul - the caster's tracking is awful Great way of seeing the effect of poor tracking from multiple angles though.

There is also what looks like late tails on my phone screen. I wonder if this is caused be the weight of the rod tip at the beginning of the stroke?

Weight of the tip can hardly cause a uneven force application

My thinking is inertia would cause the heavier rod tip to significantly deflect backwards.

Eg just like we see with any graphite rod accelerated away from a wall. The tip kicks back slightly to touch the wall. Increase the overall weight and logically it’s going to kick back further.

It might explain some of the casting issues. But it cold also be technique. It needs a test drive by someone we know.

How would that account for a late tail? All rods does it, but it's the early hot which accelerates the line downwards, not that the rodtip moves backwards.

It looks like caster error all the way
