Inventors' nook ;)

Hi slingers!

Sling is a brilliant device due to its simplicity. It seems that it is impossible to improve it. Is that true? I think that human inventiveness has no limit, however (similar like slinger's accuracy Wink

). I have started this topic with hope that that one will accumulate all our GREAT IDEAS related with a sling.

Well, I should be as an example and start first. So, let's go.
Some time ago I had got the idea of a sling with the nail trigger (However I'm afraid that someone has invented something similar before Cheesy

, or maybe not...)

Following solution eliminates two problems:
1) necessity of having a lot room for slinging;
2) hitch the release cord by stones.

The drafts should explain all:

I have tested that and works quite well. I'm curious what you guys think about it, and eventually how it works for you.

Jurek, who invite you all to brainstorming

In the shape, structure and position of each stone, there is recorded a small piece of history. So, slinging them, we add a bit of our history to them.

I have just finished making my new sling to my own old conventional design but I should be able to modify it to try your design. I use brass eyelets to pass the cords through, so the pin should slip out quite easily. So if you don't mind I will have a go with your idea.

The brass eyelets should help. If it don't work for you well, you will come back to the traditional design quite easy. Good luck and let me know how it working for you. Jurek

It looks like the "release cord" is a little longer than the retention cord, and you just let out a little slack to release the pouch instead of letting the release cord go completely. Is that right?

Thanks Yurek, I will let you know how I get on (once I find a quiet place to do my slinging).
What type of sling do you normally use?
I use a 6 inch x 2 1/4 inch oval leather pouch with a triangular 1 inch cut- out at each end and an oval cut-out in the centre to hold the stone. The ends of the pouch are double leather with brass eyelets. I use paracord for the cords with a carved wooden bead for a thumb grip. A picture would have been easier but I haven't figured out how post pictures yet. I am decidedly lo-tech, which of course is why I love the sling Grin

The release is very quick beacause the puch doesn't pull the release cord. That release way is very sensitive, so I have bended the nail. Also it is good when the cords aren't separate by the fingers exessively. But if one tune all up it will work without fail. Jurek

Yurek, a very slick design! I know the missile slides along the release cord upon launch from a standard sling. In time that cord shows a lot of dirt and wear along it's full length. I've often wondered just how much that sliding friction reduces launch speed, ...if it does at all. Any idea? Does this new design seem to offer improved launch speed & range? Does the mechanism at the pouch increase air drag and slow the spin? So many questions? Grin

This should be a great topic. mgreenfield

I have to try it and compare with conventional design, thoug it seems to me that as much mechanism less performance, but it looks simple too. I wonder about the actual advantages... It´s an excellent idea this inventors corner !!!

Guys, I'm glad that it has interested you.

I think that additional air drag is non-significant in this case. The release is very clear, precise and quick. As I mentioned before, the mechanism is sensitive and require a good tunning. It is better when the cords aren't too thick and stretchy. Also is good when they go out from the hand possibly closest one another. Beacause of, a small shift of release causes the release. Lenght of the nail should be resonable, the shorter nail, the more sensitive release, and the longer one, the more difficult release. My nail is above 4 cm (1.6") long, the bending is about 1 cm (0.4") long.

Pouch dimensions and the lenght of the nail and bend depend on your max ammo size. The hole on the release ending of the pouch should be enough big for easy releas. If neccesery that one should be reinforced by leather piece or eyelet. Propely tuned sling shouldn't give an uncontrolled release and a weight of stone should cause openig of the pouch when you release the cord.

I should add, that that release way is unsensitive for twisting cords.

David,

I have put the drafts into the post in the same way like other pictures.

If necessity is the mother of invention....then surely us slingers, we odd lot, find ourselves her scattered children! Your design is quite similar to a device I used with my 'shot pockets' for a quicker and smoother release to produce symmetrical shot patterns.

Me thinks that this should make the concrete slingers very happy; no more tore up release cords! How COOL! How COOL. Now to make it adjustable for length and you would have ultimate slinging tool. 8) 8) WalkingBird
