Absolute maximum slinging length
Jul 2nd, 2017 at 11:19am
 
Hi.

I'm planning on making an enormous, maybe slightly over the top sling.

What do you guys think is the absolute maximum length you can make a sling while not losing practicality?

the point of this is obviously to get as much range as i can with this.

My longest sling is a massive 115cm long from the centre of the pouch to the end of the release cord and to be honest I think that's getting close to usable with regular throws. I have to use helicopter style with it but I have managed to pull off a fig 8 throw a few times but each time it felt like my arm was going to come off. Changing the throwing technique to be like a hammer toss (spinning around and then throwing which is the style Timpa uses) would probably mean you could make longer but you can say goodbye to anything like accuracy at that point. Cheesy I can count on one hand the number of times I've had a successful shot that's landed exactly where I want with my long sling so even longer is going to be really difficult. I find with distance I can actually get a lot further with shorter slings but that may be because of the construction of the sling. It has a very wide pouch and the cords are braided cotton so not the lightest and thinnest. With distance I think that is more key than length. If the sling can move through the air quickly and impart most of the energy into the rock (or whatever ammo it is) then that is what will give you distance.

So in conclusion, You can get them pretty long but if you want distance you really need them light and thin. At least that's my opinion Cheesy

Isn't it a problem when you have such a huge sling to make it thin while not breaking it due to the centrifugal force?

also, i'm guessing i'm gonna make mine about 1m from the center. that sounds decent enough i guess.

some more questions:
what i was using for my previous slings was regular 4mm cord, three-strained with two cords per strain. should i keep using this way of making them and switch to thinner cord? or should i just make them in a different manner entirely? and if so, what cord thiccness is best?

also, to prevent confusion, are slings always measured from the center of the pouch to the knot?
i'm new here you see...

Thanks a lot Smiley

centrifugal force will lower if the radius of curvature gets longer.
but longer slings have more circular wind ups than shorter slings which have more ellipsoid wind ups.

so a longer slings may end up having the same amount of centrifugal force of shorter , that may explain why some get longer distances with shorter slings.


i once used 3m sling from 0,8mm rope and heavy rocks, i tried pirouette(better) and underhand while standing on a rock , results: boring loading and wind up and relatively weak throws.


if you are going for pirouette style do experiments on lengths if you are going for non pirouette style then 1,5m is probably the limit.

pirouette styles have very good potential for range but not accuracy, it also needs a lot of training.

I wouldnt worry about your sling breaking from centrifugal force. Any decently strong cordage will stand up to it without a problem. Paracord for example is rated at 550 pounds. If you got anywhere near that during a throw you could kiss your throwing arm goodbye.

Really thin cords aren't actually that necessaary.
Both luis and jaegoor tend to use fairly heavy duty distance slings. The weight of the cords actually helps get it up to speed. You're essnetially smashing your way thrugh the atmosphere rather than trying to slice your way through.

The absolute length ofa sling depends to a certain extent on how tall you are.
Around 50 inches is about the practical maximum.

Weirdly while I tend to use metric for all other measurements - height of a person and sling lengths, only seem to make sense in imperial noidea

I think it sounds weird to use the metric system in the English language. I just still use metric cause im used to it.

Mine turned out to be around 110cm. Which i'm guessing is somewhat appropriate to my height, since i'm 193cm.

I'm probably gonna make a shorter one though, cause i find it only works well with the pirouette. The pirouette technique was a lot easier than i expected, btw.

When you first start slinging super long slings are a viable way to achieve  great distance. As your form improves you'll find that such slings are no longer necessary. Through much trial and error I have found that for any style but Pirouette, which is fun but innacurate, a sling half the length of your body, folded length, will give you the most distance. That said, I would never tell you to not experiment. Make super long slings and have some fun launching ICBMs.

I still struggle getting better range on long slings, my best range comes from about 32-33'' paracord/leather pouch or paracord seatbelt sling.

It just feels a bit woolly above about 36'' for me, feels like my arm action overtakes the sling unless I slow it down deliberately. You can throw heavy rocks more easily though.

yeah with longer slings, technique becomes crucial.

As a short arse, I'm good up to about 40 inches. But no good on slings longer than that.

"yeah with longer slings, technique becomes crucial."

That's been my experience as well. I am no distance slinger and don't have the skill to use a really long sling effectively.  They can be fun though, especially with very heavy stones for maximum destruction.

As said before, it throws really well with the pirouette, but it really seems to only work with the pirouette. Confirming what Aardvark said. It did however get me about 100m of reach (estimated) with some rather crudely made and very heavy and big concrete projectiles. So when you're just looking to have some fun and see some nice destruction (which is what I've mostly been doing so far) it's just for you.

I wish I could see some cool destruction with my long sling but I basically never hit the target Cheesy
