Topic: Craker

I like tapered crakers but i dont want to do them all the time. I think they make it easier to get that flow go all the way to the crack. I like to have some lenght in the fluffy section but that usually gets tangled so i have to cut them off and tie a knot but that messes up the taper after while.
Making them takes lots of time and material so i wanted to make them last more.

I tought that if i would make the fluffy section replaceable i could save some time.

This is a prototype so have not figured out how to make the thik end look better but it works fine. When the tapering portion gets fluffy i just use my lighter to make it nice and smooth again. I can make those boom ends pretty quikly and with less material. I have used this one quite a lot already.

What do you think?

Surely a different and unique approach.

Jyri, thanks very much for this. I shall do some playing about....

Cool idea!

Re: Craker

Jyri - I think I've seen people use  series of diminishing sizes crackers. I think the ideal whip would be one that smoothly diminishes it's thickness along its entire length, so I believe there is merit in this.

If I can't run fast, I'll make slow look impressive.

Re: Craker

Jyri, that's an interesting idea. Please keep us posted on how it works out.

I'll give it a try, Dad, but it's going to be really hard...kind of like trying to saw something in half using a banana.

Re: Craker

Thanks!
Thru my testing there hasn't been any broblems so far. Its just that butt end i'm struggling with. How to make it look better that is.

Re: Craker

Here it is. Not loud yet as the tip haant opened yet. Feels good.

Re: Craker

It looks like it works well.
Thanks for the experiment.

Jyri, this does look very worth trying. Thanks!

Re: Craker

I really like the idea of a replaceable ‚fluffy part‘ of a cracker.
However I‘m on the sceptical side when it comes to the idea of a tapered cracker improving the performance of a whip. I would really like to see a zoomed super slow-motion of the actual crack not only for this but any kind of whip.
Of course a good taper of the plaited part of a whip is bread and butter, but there is a transition to the fall with sudden change of weight/diameter and inner friction which should cause a sudden acceleration once the loop has rolled down the whip which sometimes is enough to make a whip crack even when there is no cracker at the end. (This happened to me a few times, the cracker had come off as it tore through the end of the fall and I was wondering why the sound of the crack changed). After the fall has reached its point of maximum extension another acceleration of the cracker will make the sonic boom.
In the slo-mo section of this video
https://m.youtube.com/watch?v=XavzX0djEkM
it’s visible, that the loop doesn’t travel all the way down the fall and that the fall is moving in a rotational way around the point where it is attached to the thong.
So there is two motions, a loop-wave followed by a rotation around a fixed center.
Okay, my point simply being this: If the whip is not one piece absolutetely continuously tapered down all the way down to the cracker (like e.g. in a signal whip) I don’t think a tapered cracker is improving the performance or „crackability“ of a whip.

Is there any difference here?

Re: Craker

Wow that is a great video! The whip is faster here at the end because of its length, but I think the first two cracks show a similar pattern as in the volley video: The loop travels down to the fall which then snaps upwards and subsequently causing the crack.

Re: Craker

Hit reply too soon...the forward flick at the end however looks as if the loop travels all the way through to the end. Difficult to tell. Is this whip plaited down to the cracker or has it a tapered fall?

Re: Craker

It has english eye and just normal 550 cord fall, 2 gutted 550 cords inside each other.

Re: Craker

One thing is sure: This is one great looking whip! I find it interesting, that the cracker is longer than the fall.
There is probably an optimal length of thong to length of fall to length of cracker ratio that might depend on the type of whip , thickness of the thong etc.
This can probably be calculated with a finite element computer analysis similar to the equations which where recently posted in the taper-thread. Only it’s even more difficult because in that paper they used a simplified model that didn’t take the points of unsteadiness (material, diameter change) into account that are located at the fall hitch and the cracker knot.

Re: Craker

I think a person can over analyze things that it makes things more complicated than it has to be.

There can be no perfect mathematical formula for whip making when the variables are so numerous. That's not to mention the human variable in cracking style. Don't forget the different plaiting styles and the  different behavioral qualities of materials.

It can be used as an overall template but not as an absolute.

That would be an interesting experiment though to try to figure one out.
