My cleanest throwing sling has been with paracord and a tab at the end. Basically the closest to reverse taper you are likely to see.

I wonder how much it really matters that a release cord is tapered? Is the stone really that likely to contact the end of the cord? I think the only time Iíve had this happen was when using very poor ammo which didnít release cleanly due to the ammo not the sling.

Maybe certain throwing styles and/or set ups are more prone to such problems. To my knowledge it hasnít been a huge issue with my paracord slings.

Come to think of it a stone is a lot more likely to contact the near pouch portion of the cord so wouldnít it make sense to have that as small as possible?

The ammo should be out of the pouch after the release cord has moved outward by half the length of the pouch. Itís only a few inches. The mass distribution shouldnít have a huge effect either way. The biggest reason to taper is for that supersonic whip crack.

I really do advise to buy one of Luis slings. His slings are some of the best

I've whipped myself pretty hard just with a knot and it can sting like hell.

I understand what you say now Mersa. You are right about a taper hastening a release.
That does not mean that an extremely tapered cord (i.e. very thick a the base) would release quicker than just a straight thin cord (the misunderstanding). And if there's a fluffy end it will slow it down again.
Before I tied a little weight I had a knot. To my mind it felt as if it released quicker with the tiny weight. I added a larger weight and it slowed down again. That means it can't open up quicker with more weight at the end. It is counterintuitive.

But now that I have removed both the weight and the knot it feels as if that gives the quickest release. No knot, no weight, no tab, no fluffy tail. Just the thinnest cord possible


I quite enjoy reading your posts. It's almost like a stream of consciousness.

I was thinking that a weight on the end should impede the sling from opening faster, but I held my tongue in the occasion of you coming back with video evidence proving me wrong Smiley

Actually, I was thinking that if you had a small weight on the release side of the pouch might help with opening. Because the weight is out at a larger radius in the rotating reference frame (with the same angular velocity), the force on it should be larger, allowing more acceleration and hence the pouch should open faster.  So the balearic sling design may actually be something the helps to open the sling, given it's overall large mass. Of course thin and light should "open" faster.  And I say "open" because it simply means that the sling is out of the way, enough for the projectile to get by. A heavier sling has more inertia and can affect the projectile more by being in contact with it.

I agree IG , Iíve always pondered the idea of a weight on the release side of the pouch to help open the sling but truth be told itís only a thought and Iíve not tryed it in practice

(Sigh)... I really do need to set up those high speed video experiments.  Iíll add cord mass distribution to the list of experiments to try... some day.

Not to be a huge downer but release timing is far less crucial imo than is being made out to be in this thread.

The crucial part of it is consistent release timing. So long as it happens consistently from one shot to the next thatís all that matters for target and perhaps even distance. On a decent throw the stone is already exiting the pouch in a matter of tenths of a second.

That being said Iím a hypocrite  as Iíve considered for years putting a weak elastic cord on the release side of the pouch to flip it open faster. I never did because I canít reason out how that would actually help. Interesting idea though.

By the way, thereís two extremes to consider for pouch opening: one is where the release cord swings outward without bending... opening the pouch like a hinge. That would be the slowest mode of opening the pouch because the entire release cord has to swing 180 degrees to completely open the pouch. The other extreme is where the release cord moves outward, parallel to the retention cord, gliding directly away from the slingerís hand. This rolls the pouch open and is the fastest release because the pouch will be flat after a few inches of motion.

Real slings will do something in between these two behaviors. The pouch rolls open and the release cord also swings away. If a particular weight setup reduces the release cordís outward swing, then it will release faster, but added mass will also slow the acceleration of the cord, so for any particular motion, less mass will open the pouch faster. 

Howís that for a complicated non-answer? Grin

Obviously we need experiments and high speed video to get a real answer.

@Morphy, If you buy into the hinge versus glide model above, it may very well be a source of inconsistency in the release timing if the sling opens differently each time.

(I suspect the slinger is still the most significant factor most of the time though)
