Tutorial added at link above

This is a light duty sling for throwing tennis balls. Structurally not the best idea to make a two-part pouch connected at the point of highest loading! But just because it is a dumb idea doesn’t mean it can’t be done!!!

I have not seen anything similar (likely because it truly is a dumb idea!), so maybe I have invented a new type of sling construction??

In any case, very fast to make. Basically tie 3.25” loops at the end of two paracord strings. Then connect those loops together in their centers and the sling is done.

Love to gear your comments, including your prediction many tennis ball throws before the pouch explodes in two!

At least the whipping hides the pouch is really two separate paracord loops. It will take a closer inspection to see this sling is put together illogically.

Oh, it looks interesting! The only thing is, the connection point is where all the inertia rests...
What didn't you like about the regular three-line design in the bag?

If you're interested in the direction, scroll back a few pages; erricrice made a very similar noodle-shaped construction, only using dyneema and avoiding knots.

I like the noodle sling for it’s simple construction. It does throw great too.

Just I prefer not fiddling with split pouch/noodle strings every time I load a tennis ball.  I like the convenience of a solid pouch. So I created a “cage” sling to fix the noodle strings in position.  Then I did this Twin Loop sling as an even simpler-to-make “fixed position” noodle sling.

If I had some quality leather likely an Aussie pouch would be ideal. But right now all my materials are slippery nylon webbing, paracord , and mason line. So just trying different designs using materials on hand.


You are correct the loading was moved to the weakest component… basically the opposite of good design!  Paracord breaks at 550 lbs, mason line at 150 lbs, so quite a reduction. Definitely not ideal but for tennis balls should at least be not too unsafe.

I do like the simplicity of the design! What kind of webbing do you have? If it is tubular webbing, perhaps using a short piece of that as the connector and running the loops that make up the pouch through that tube before tying off the loops would work. It would give you a similarly quick and simple construction (arguably quicker) while giving you a much stronger connection for the center.

Brian:  I have 2” wide flat nylon webbing. But I see your idea would be an improvement for sure. Either a one piece pipe (not sure where to find one of correct diameter)…or a series of stacked beads (ranger beads are very common).

So far the Twin Loop sling is working perfectly. No issues with the mason line common whipping at all. But just for fun, today I made another Twin Loop sling but this time instead of the mason line I used 550 paracord west country whipping to hold the pouch together. Cosmetically does not look as nice but it must be stronger I think.

Ive found the west coast whipping (WCW) can hold up way longer than the standard whip, but yeah its not as neat looking.

Im going to have to make one of these and see how they throw! Its an interesting overall weight/balance sling since all the mass concentration is at the very end of the pendulum (bottom of the pouch) and theres no excess material anywhere else besides the knots.

Love to get your impression, swiftcreek.

Had not thought about weight distribution…that is a very good observation!

I used figure 8 follow through knots to tie the loops. Lot of paracord in those kind of knots, so there is a chance to use lighter knots for sure. I was thinking a “flat” knot would be better (figure 8 follow thru did wind up kind of flat on one side), but was not thinking about a lighter knot would be better.

And the sling I made was 32.50” long, so a bit shorter length would make the pouch center even a bit higher percentage of the overall weight.  I did not accurately measure but I think I used around 28”-30” of paracord to do the whipping.  So the whipping paracord then was roughly the same length and therefore the same weight as the retention cord. Interesting.

Maybe there is a chance to use some other, heavier cord than 550 paracord for the whipping too??  Can it be a double layer of whipping??

Very curious what you come up with. Please post a picture.

In any case, I don’t think I am a good enough slinger to describe how this sling feels to throw. I guess it feels “snappy” and opens quickly?? My first throws vs my normal seatbelt sling were off in the direction that suggested the tennis ball came out sooner or I released early (slings were same length so usually release timing does not change for me). Maybe there is less drag on the ball as it leaves the pouch since the pouch is minimal??  Just guessing what happened, but it threw well and I really like it. I kind of think the tennis ball had a lot more spin too…but the ball went straight, no curving, so maybe wrong on this. Maybe when I use it more I can better describe it.

Honestly, I think my main feeling using this sling so far is just a feeling of surprise the pouch has not failed yet!! I am in shock this thing even works.

I love your analysis! In the end all of us are just making our best interpretations of the anecdotal data we collect.

I could see it releasing early for sure. There is so little mass and material in the way of the ball when it flies out. i would think this would put less spin on it but there are other factors at play too. Depending on how large the loops are that will determine if the ball really has to roll out of the pouch or if it can just teeter off the edge if that makes sense.

I usually make my sling pouches as small as i can for the desired ammo to be comfortably sat. My thinking is just to have as small amount of material possible impeding the projectiles natural momentum path as possible.

I was thinking of making two eye spliced loopps and connecting those so as to reduce the side profile and get rid of knots.

No knots would be awesome!

I am not that familiar with splicing. Is there any way to replace the whipping used to connect the pouch loops with a splice?

Under the whipping there are essentially two separate paracords side-by-side, running parallel to each other. Can you splice two separate, parallel cords into a single cord?

Keep in mind part of the reason for me is the whipping is stiff and so fixes the position of the pouch strings so I don’t have to fiddle around with adjusting the pouch to fit each time I throw a ball.  Would a splice be stiff too?

Forgot to add: concerning your comment about the tennis ball rolling out of the pouch.

Not sure what happens when you throw it, but statically before you throw it I do know the pouch will hold the tennis ball even if the sling is horizontal.

When I created the pouch I played around with loop sizes and whipping length until the pouch held the ball when the sling was able to hold the ball horizontally.  I used masking tape to temporarily hold things together until I figured out all the dimensions.

Maybe this is excessively “gripping”??  I would guess if you reduce the amount of initial pouch grip (by changing the dimensions I used, for example), perhaps the pouch could release quicker. 

UPDATED REVIEW.

swiftcreek mentioned the weight/balance of the Twin Loop sling, so today I purposely tried to understand how this Twin Loop sling feels to throw.

I compared a standard seatbelt sling (with 7” long, 2” wide nylon backpack webbing for the pouch) with both the orange, mason line common whipping version of the Twin Loop and also the black 550 paracord west country whipping (WCW) version of the Twin Loop sling. Here is what I found.

Feeling due to spinning the sling:    The black WCW Twin Loop sling felt noticeably heavier loaded with a tennis ball and marginally heavier when spinning with the pouch empty.  The weight was all in the pouch, making this sling feel like it was loaded with a “heavier” tennis ball. Both of the other slings felt much lighter, and in fact, I really could not feel any differences in how the mason line whipping Twin Loop sling felt and how the seatbelt sling felt. Subjectively I would say these other two slings were the same sling in terms of feel.

Accuracy at 20 yards:     All slings were the same length so that should not change accuracy. I also threw only 2 tennis balls and then switched slings and kept repeating this to prevent “dialing in” any particular sling. Style was Byzantine.  The seatbelt sling was accurate with my typical scatter of misses generally to both the left and the right of the target.  The orange mason line whipping Twin Loop sling was similarly accurate but the misses were clustered more to the right of the target (as if the release was early). The black 550 WCW Twin Loop sling was very much more accurate. All the misses were much, much closer to the target and much more consistent-really felt like the tennis ball goes where I aim.




All in all, I like the heavier feeling Twin Loop sling put together with the 550 paracord west country whipping. At least for throwing tennis balls the sling felt and performed the best for me.

I didnt think about splicing those two parallel lines together where youve got it whipped now. I feel like it could probably be done but figuring out that splice before doing the two eye splices for the loops could be challenging. I need more splicing experience.

It would be stiffer than a regular cord but not as stiff nor as dense/weighty as the whipped connection. Which will have some small effect on how it feels.

Regarding your last paragraph, those are my thoughts exactly. When i make mine i will make as small of loops as i can while still being able to safely nest the ball inside.

my motto of sorts regarding this is to make the projectile sit as precariously safe as i can.

I have an idea!
Where your knots connect two loops, you could create a "cobra" weave, like paracord bracelets or the "Primal sling" pouches they use on their slings. This would still keep the weight centered and increase the contact patch.

For side knot removal, try the Brummel Eye Splice and Brummel Lock Splice. This can be done not only with dyneema but also with paracord, if you partially or completely remove its inner strands.

That is a neat idea, pocket rocket!

A cobra weave would definitely look so, so much better cosmetically than west country whipping. The cobra would be flatter too and likely conform better to the tennis ball shape. Likely that would also look better and maybe even grip the tennis ball better??

Cobra weave I think uses more paracord (never made one so am guessing), so that adds even more weight to the center of the pouch.  I like how the west country whipping makes the tennis ball feel heavier, so likely I might like the heavier cobra weave even better.

I am out of paracord, need to buy some more. Will have to try this cobra weave. Might be this fall when I get back as going camping for two months this summer.  Got to learn to do a cobra weave first as well. If you are able to put one together would love a picture please!


Honestly, I really don’t completely understand why I like how this WCW version Twin Loop performs. Except for the “heavier tennis ball” feeling that is explained by the weight of the whipping added to the pouch center, not sure what about this sling feels “snappy” and feels like it releases quickly, nor why the tennis balls fly straight (no curve) and accurate.

I was thinking the west country whipping looks kind of like a stack of “beads”. The tennis ball contact is a single point on the outer surface of those “beads”.  The pouch grip is minimal with such a small contact patch. And maybe the “beads” let the tennis ball roll out of the pouch instead of the tennis ball sliding out of the pouch???

No idea. Can’t explain how the sling works. But it is very nice to throw and is becoming my favorite for tennis balls.

I once made something like this for a bracelet to attach a slingshot to my arm, but not for a sling. The weaving is not difficult and yes, I assume it will require a little more paracord than you have now and will therefore add weight.
As for me, thank you, I'm still happy with the "minimalist noodle-shaped survival slingshot" for two years now, despite trying various other designs. :)

I still havent found time to make one so i dont have actual experience with it but my hypothesis is very similar.
Basically that you get the added benefit of a little more weight to feel as you sling around and release, without the negative of that extra material and mass in the way of the rocks trajectory. Since its all just single cords besides the center; the light, supple strands conform really easily and smoothly without disrupting the natural momentum path the mass the projectile has built up over the throw. This would explain the early release, low spin, and general accuracy as the actual trajectory aligns better with your expected trajectory due to the lack of resistance pushing it one way or another.

And yeah I was thinking of the cobra weave or also could do an over/under finger weave with one or two strands. Or i could see a small four or six strand warp woven rectangular patch running perpendicular to the pouch orientation being a very effective glande sling. That would be a little more complicated to figure out though.

You guys have great ideas!!

I don’t know much about tying paracord honestly. Sounds like if could get rid of the whipping the sling would be stronger.

Can the sling be made in this manner?  Instead of whipping, just directly weave or make a “chain of knots” to connect two strands of paracord….leaving plenty of paracord sticking out the top and bottom of the weave/knot chain.

Then tie the paracord sticking out the top to the bottom paracord to create the 3.25” loop….one loop on each side of the weave/knot chain. The bottom paracord would left long and become the release/retention cord.  Poof!!  The whipping is eliminated and the Twin Loops are directed connected in the weave/knot chain at the center of the pouch.


If it is possible to make the sling this way then that does not seem hard to make (if I knew how to weave/make a knot chain that is). 



The way I made the sling was a conscious effort to make something that was very, very simple to me (tie 3.25”loops at the end of paracord, then whip the 3.25” loops permanently together). Very simple and very fast to make too….but the Twin Loops will always have that weakness the entire thing totally depends on the whipping carrying the load.  Thankfully tennis balls are so light!
