@Sarosh - Well done.  That thing is definitely a piece of work.  I'm interested in seeing your development with it.

Does it feel as though your getting a more powerful throw than with a normal sling?  Or potentially could?

Title: Re: Compound sling vid
Post by Sarosh on Apr 7th, 2019 at 3:40am
@ timpa
can't wait for your idea

@ joe_meadmaker

can't really tell. the trick would be to feel just normal but produce high speeds. heavy slow movements to produce a fast cast.

I didn't throw for range... so i can judge the power only from the hits on the wall and the cliff, and they sound normal, what would be a 45-50m/s throw.

in the video is every throw I've done till today . It potentially could be better, a longer sling with better tuned release angle. and a better booster mass:projectile mass ratio.

what i've learned is that the sliding mass is better than the fixed and that the 500g are better than the 1kg for 30-150g ammo.

oh i should have put this in the video :P I'll put it in the description

that's a pretty good start :thumb:

Just need to be able to use it without getting dizzy and falling over :-)

The original idea is to hold the missile and swing with the larger weight.
This builds up more energy than you can put into swinging a small weight.

My original plan was to use it for slinging paintballs.
They work great from a catapult, just too light fora sling. Although using a weighted pouch can help.

Probably best to use with a shorter sling though, both for practicality and simplicity :-)

This is looking really promising. A tuned up version could have a really powerful throw.

if it was made for paintballs then a lighter booster mass would be suitable 50-200g like normal ammo mass, at that mass a shorter sling would be better than a pirouette length sling.  I don't think weighted pouch would be needed for the paintballs.

practicality and simplicity are already compromised :P

pirouette allows me to safely and efficiently use 500g-1000g booster mass and throw ammo of the same mass as with the simple sling .

next level would be using hammer throw style, 5-10kg booster and holding the projectile with the teeth  ;D

you use a weighted pouch for slinging paintballs with a standard design sling :-)

Tryig to sling a really light weight, causes joint and muscle issues. It's like throwing a punch and missing.

It's what got me thinking about the compound sling in the first place :-)
While ago now - probably still got the paintballs too !

@Sarosh: that’s a very nice start! please post the drawing and some photos on here too so we don’t have to pause the video to get a good look at the sling.

@Jaegoor:  The purpose is clearly stated... the goal of a compound sling is to achieve higher velocities with smaller projectiles, but this comes at the cost of increased complexity. Sarosh is demonstrating a proof of concept, not an optimized system. If you see no purpose, it’s probably because you lack the imagination to see past the flaws of an early prototype.

anyone trying to figure out a better trigger/ or a mod that could release exactly when the main cord straightens out? :-/

Title: Re: Compound sling vid
Post by joe_meadmaker on May 25th, 2019 at 12:15am
I have made an attempt at a compound sling.  Forewarning and spoiler alert, this attempt was pretty much a failure.  But I am going to make some adjustments and try it again.

First things first.  Here's a picture of the sling:



I'll try to explain the setup without being too confusing.  There is a main retention cord permanently attached to a weight.  In this case the weight is a red plastic ball filled with silicon.  This is not ideal, but it's what I had available when building this prototype.  Another permanent attachment on the weight is a secondary retention cord that connects to one side of the pouch.

The other side of the pouch is attached to primary and secondary release cords.  The secondary release cord has a loop which is wrapped around a post on the weight.  The primary release cord is made of two pieces of cord.  The reason is so that it can come down on both sides of the secondary retention cord, and help to hold the projectile in place while the sling is rotating.

The basic idea is that when you let go of the primary release cord, the pouch is allowed to swing free on the secondary release cord.  As the pouch extends out, the loop of the secondary release cord will slip off the post on the weight, releasing the projectile.

There are a couple adjustments I tried to apply that differ from the design by Sarosh.  One is that I wanted to make the sling one handed, so a windup could be used without rotating your entire body.  Second, I wanted the projectile to be in a rotating motion during the windup along with the weight.  The hope is that less energy from the throw is needed to get the projectile moving when the sling is released.

Here is a video of this sling being used: https://youtu.be/5oPGFPuNbwY.  Sorry about the distance.  I was trying to stay far away from my phone during the recording because I had no idea where the projectile was going to go.

There are a few problems with this sling and the attempt.  One is that the weight and the projectile I'm using weigh the same.  They are the exact same red plastic balls.  Again, this was not ideal, but what I had available at the time of this test.  Second, the cords on the sling came out shorter than I wanted.  The sling needs to be spun around too quickly and it's difficult to see what's happening during the release.  And related to that, because the sling is spinning so quickly, it makes it much more difficult to time the release.  My first throw almost hit my phone (which I was using to record).  You'll see that in the video.

I'm not sure when but I'm planning to remake this sling with longer cords.  I also want to test with a projectile that is smaller and lighter than the weighted ball.  But for the moment, this is my attempt.  At this point I think the design by Sarosh is much more effective, but I'll report back after the next trial with my design.

Feel free to throw out any thoughts or ideas.  This is by no means a completed design  :)

Thanks for experimenting it's nice to see other people trying it too. :D

if the projectile mass is rotating then it means you put energy into it,
if the mass is low, the energy you put is negligible, the speed is also low so no reason to do that.This way you shorten the cord between booster and projectile which limits the arc of accelerating the projectile (bad).

if the projectile mass is high then the best place to put it  in order to put max energy to it is at the biggest radius, where the booster mass is, that would mean you got a simple sling but also a booster mass that steals you energy.

i would say you shouldn't care if the projectile mass has initial speed or not since the ratio should be: projectile mass<<< booster mass .energy should transfer from body to booster to projectile like a whip.

On the release mechanism:
I can't say i have completely understood how the secondary release cord releases from the pin on the red ball. how easily would it misfire?
i don't like non sliding booster mass because when you release the primary release cord the secondary cords will relax at first and then be pulled by the booster mass. And the booster mass retains a lot of it's speed which means low efficiency.

you should try it with a much lighter projectile mass, 5-10 times lighter than booster and see how it behaves.
you can lengthen the secondary cords and remove the primary release so that you pinch and release the projectile pouch, leading to longer arc of acceleration.

I agree with you on these points.  But there is another point that I forgot to mention.  Having the projectile in motion was also intended to help keep it in the pouch until the secondary release cord is free.  But you could be right.  This may be completely unnecessary.

The pin in the weighted ball is just a small nail.  Which is also something I want to change, because it makes me nervous.  The secondary release cord basically has a finger loop tied at the end which is slipped over this nail.  During a throw, when the pouch is released, it will extend to the full length of the sling and the secondary release cord will just fall off the pin.  I'm not a big fan of this method.  But it's the only thing I can think of for an automatic secondary release.

There is another thing that comes in to play.  With a primary and secondary release cord, there is a lot of cordage that could potentially be in the way of the projectile when it is released.  When I remake this sling to lengthen the cords, I think the retention cords will be left as paracord.   But the release cords will be replaced with something thinner and lighter.  Probably hemp or flax because I have a lot of that.

Definitely agree with the lighter projectile.  Especially being that one of the original intentions of the compound sling was to throw small light projectiles.

I like the idea of having just one release cord, but because my design doesn't have a moving booster weight, I'm concerned that the pouch won't get momentum quickly enough to hold the projectile.  I will think on that though.

Thanks for the input.   Hopefully I'll have some new results soon.  :)

Post by joe_meadmaker on Jun 13th, 2019 at 8:44pm
It took me a while to get around to it, but I finished the second revision of my compound sling.  Here is a new image.



The basic functionality is still exactly the same as in my previous description.  There are two changes with this revision.  The release cords have been replaced with thin braids of linen.  It's lighter and not as stiff as paracord so I hope it allows the sling to open more easily.

The second thing is I extended the length.  I don't think I ever took a measurement of the original.  The current sling has a length of 42 inches (107 cm) from the finger loop to the center of the counter-weight.  Once the sling is released, center pouch will extend to 58.5 inches (149 cm) from the finger loop.

The original was so short that it didn't allow any time to see the release of the throw develop.  I don't know if this one will either, but I have higher hopes than before.  One last change I'll be making is to switch the projectiles to golf balls.  The last time the projectile was exactly the same as the counter-weight and that was definitely causing problems.

I haven't had time to give this sling a try yet and I don't know if I'll have a chance this weekend.  But I'll get to it as soon as I can.  There will be video and I'll post a link once it's up.

Title: Re: Compound sling vid
Post by joe_meadmaker on Jun 23rd, 2019 at 1:07am
I had a chance to try my revised version of the compound sling.  It's still not working very well, but it was an improvement on the first attempt.

The changes (which are detailed in my previous post) did make the sling a little more consistent.  Other than a couple misfires, one of which is the first throw in the video, I was able to pretty much throw forward.  But I think the projectile is being release earlier than intended.  I will give this version a few more sessions and then hit the drawing board to determine what my next adjustments will be.

This video also shows the setup of the sling better than the first one did.

That looks like good progress!  FYI, I’m working on a pouch design specifically to solve the retention and release problems with a compound... I hope to have something to show in the next week or so.

@ NooneOfConsequence

Thanks!

Looking forward to seeing that pouch.  That is one of the larger concerns at the moment.  And not just releasing at the proper time, but also holding the projectile until the time of release.

Title: Re: Compound sling vid
Post by NooneOfConsequence on Jun 23rd, 2019 at 11:50pm
Yup... hopefully I’ll have a good solution to that. It still needs a little more tweaking and testing to be sure it works though.

Title: Re: Compound sling vid
Post by Morphy on Jun 24th, 2019 at 5:50pm
Could one simply scale down the sling considerably to make a more user-friendly design? Obviously this doesnt fix the release issue but just a question I had watching Sarosh using it.  If you guys could get this thing working to the point it could be aimed that would really be something else...

One thing I try to work on with my own slinging throw that has added a great deal of control, is to focus on slowing arm movement down as much as possible while increasing sling lag to the optimum point. Creating essentially what feels like a very efficient high gear ratio between arm and sling.

But this design takes that concept to a whole new level. I would think if the bugs could get worked out you could have very low arm movement (giving extreme control) while maintaining high velocity. Anyways just a thought.

Nice job Sarosh!  [smiley=thumbup.gif]

Ok. Here it is! Ring Sling 2.0:
I had some time this evening to build a rough prototype non-compound sling to show the mechanism for a compound sling... it’s functionality is similar to my original ring sling, but construction is simpler and you don’t need a big heavy metal ring.  This version ejects the tennis ball reliably and holds it securely until the release. I’ll try to get better photos and a video, but I ran out of time and daylight tonight.

thanks morphy

I tried recently to scale it up to a 5m main cord using the same trigger style. The thing became too tangly and unreliable on the release timing.
A new trigger release design is the main problem to be solved, then scaling up or down will be easy.

P.S.: that means, on my end this project is stalled.

@ NooneOfConsequence

That's genius!  And I think it could definitely work for a compound sling.  I may need to make a completely new sling to try and incorporate this pouch, but that will be next on the list.  Thanks for posting!  :D

Title: Re: Compound sling vid
Post by joe_meadmaker on Jul 6th, 2019 at 2:17pm
Compound sling revision 3.  This version has the pouch designed by NooneOfConsequence incorporated.  You can see an image of his pouch earlier in this topic.

I made one small change.  To the retention cord that wraps around the projectile while it's in the pouch, I added a small leather tab.  The intention is to create more surface area for the cord when it's pushing the ball out of the pouch.  Here are some images with an orange ball held in the pouch as a projectile:

 


And here is the full sling:



The primary retention cord is paracord.  The secondary retention cord is braided linen.  And the release cord is also braided linen.  The booster-weight is the same thing I used in my previous versions of this sling, it's a plastic ball filled with silicone.  It weighs approximately 130 g.

Now on to the most important thing, how well does it work?  I'm not yet certain, but I think shows promise.  I've only done 6 or 7 throws, which I tried to record, but it's so hot and humid that my phone just quit recording.  I also had the angle wrong, so I wasn't even in the frame for most of the video.  Needless to say I just deleted it and will record another.

I was planning to do another recording right away, but a little rain came through and bumped the humidity up from 100% to what feels like 120%, so I'm not doing it today.  But a video of this thing in action will be coming soon.

The only real feedback I have at this point is that the pouch may not be releasing the ball as cleanly as I would like.  But if that turns out to be the case, I have a few ideas that may help.

Title: Re: Compound sling vid
Post by NooneOfConsequence on Jul 7th, 2019 at 10:33pm
Very nice!  I noticed on my first few prototypes that the ring pouch works better with just a little slack. If it’s too tight around the ball, you will get inconsistencies in the release.

Title: Re: Compound sling vid
Post by joe_meadmaker on Jul 16th, 2019 at 7:33pm
Here is the video of version #3.  There has definitely been some good progress.  The sling in this video is the one pictured in the post above, with the pouch design from NooneOfConsequence.

Some thoughts on this version of the sling.  I like this pouch design much better than the one I was using.  It works using the same concept, to hold the projectile in place until the sling is released.  It just does it way better!  The throws feel much more controlled than the version #2 sling.

That being said, I believe the release of the projectile is still the biggest problem.  I'm going to make one more sling (at least that's the current plan ;)) to incorporate three more pouch adjustments.  One will be to make it with a thicker material so it's a bit stiffer.  The second is to make it just slightly larger so the ball will come out easier.  And the third change will need to wait, because it's a little difficult to explain without picture.  Once the sling is ready, I'll post photos to show what was done.

Check out the video and let me know what you guys think.

Post by joe_meadmaker on Jul 16th, 2019 at 7:41pm
Oh, almost forgot.  Just to give an idea of distance, most of the throws are in the 20-30 meter range.  Although that's a very rough estimate because I only paced it off.  But as you can see, I'm just kind of lobbing them without much power at all.

Title: Re: Compound sling vid
Post by NooneOfConsequence on Jul 17th, 2019 at 8:03pm
Nicely done Joe!

What’s the mass ratio for the counter weight versus the ball? And how long is your second stage compared to the first?  I’ll bet we could do some modeling and parameter optimization in the maths section.

Title: Re: Compound sling vid
Post by joe_meadmaker on Jul 17th, 2019 at 10:02pm
Thanks!

The projectile ball is 50g.  The weighted ball is about 135g.  The ball I'm throwing is just a plastic street hockey ball.  I think a golf ball would work better, but I'm still not completely confident that every throw will go forward.  My house is usually behind me or to the side when I'm slinging, and I don't want a golf ball flying toward it at high speed.

The length of the main retention cord from the finger loop to the center of the weighed ball is approximately 54.5 inches (138.4 cm).  Once the sling is laid out, the length from the finger loop to center pouch (with the projectile still loaded) is approximately 74 inches (188 cm).  As the video shows, this thing really wraps you up after a throw.  :)

Title: Re: Compound sling vid
Post by joe_meadmaker on Oct 30th, 2019 at 10:10pm
Compound sling revision 4.  This is the last one of these for me.  At least until next year. ;)

I've been working on this sling in short bursts for a while.  I had it out for a test, which failed horribly, and had to make an adjustment.  First the pictures, then the story.

Full sling:


Pouch closeup:


The big change between this one and revision three is the pouch.  I'm still using the pouch that NOC designed.  But I switched to a thicker leather than used with previous ones.  I glued in some padding to help hold the projectile in place.  And at the point where the cord passes through the pouch (this is at the top of pouch in the image), I put in an eyelet rather than just having a hole in the leather.  I hope this makes it stronger as well as allowing the cord to pass through the hole more easily.

Now the bad news.  I don't have any video of this sling in action yet.  I mentioned at the beginning that a test had failed.  I'm still using paracord for the primary retention cord.  The secondary retention cord and release cords are shoe laces.  When I first put this sling together I used satin cord.  I thought it would be light and not interfere with the projectile.  It turned out to do nothing but constantly get tangled up.  So I removed that and substituted the shoe laces.  The laces are less stiff in their movement than paracord, so I hope they work okay.

Since the laces have been substituted in I haven't had a chance to try the sling out again.  I'm hoping to be able to this coming weekend.  And as long as things go better than the first attempt, I'll record some throws.  Another update should be coming soon.

Post by joe_meadmaker on Nov 10th, 2019 at 9:37pm
I finally had a chance to do some throwing with the fourth version of my compound sling.  The link is below.

Just a couple thoughts I would like to include.  Regarding the pouch on this sling, it's tricky to balance the tasks.  You need a pouch that will hold the projectile well, but at the same time release it cleanly when it's time.  My latest rendition is working pretty well, but I know it can still be improved upon.  Another note on the pouch, this version was the easiest to load because the leather was stiff and held its shape.  That was definitely an advantage when reloading.

Ultimately I don't think this design (including all the ones I've done) of a compound sling is particularly effective.  It does work, but the original idea (or one of them) was to throw a projectile that is light in weight.  The designs I've used rely on the momentum of the projectile to open the secondary portion of the sling, and then the projectile's weight to pull it free of the pouch.  So something extremely light in weight would be a problem.

I've been using street hockey balls as projectiles, but I think I could throw a longer distance with just a regular sling.  The farthest throw in the video below was around 28 - 30 yards (25.5 - 27.5 meters).  I don't have a precise measurement because I just stepped it off.  A contest between slings will be a video (potentially my last compound sling video) coming soon.  I'm going to run a little competition between regular and compound slings and see what happens.  So stay tuned for that one.

https://youtu.be/veDKQGq1j_I

One last thing to mention, if you missed any of my previous compound sling videos, they're all linked in the video description.  I'm quite amazed how much this sling evolved over 5 months.

Title: Re: Compound sling vid
Post by Curious Aardvark on Nov 11th, 2019 at 11:43am
okay - my original ida was to use a VERY heavy primary weight and a relatively short cord. The energy used to get that moving would then be transferred to a small and light secondaty/weight/missile
I was just looking for a way to sling paintballs without dislocating my shoulder.

You seem to have a much too long primary cord and way too light a primary weight.

Title: Re: Compound sling vid
Post by joe_meadmaker on Nov 11th, 2019 at 12:52pm
The long primary came about because of a couple things.  The first thing is as you mentioned, the weight I'm using isn't as heavy as I would like it.  With the longer cord the lighter weight can be moving faster and have more energy.  I have an idea to make a heavier one with some lead, but that's on the table for next year.  I do have a concern with getting the weight too heavy though.  Something I've experienced with these slings is after the release the weight has come around and hit me.  So far it's usually just been little bumps on the leg, so not a big deal.

The second reason was to more easily find the point in time to release.  I don't know if everyone will get this analogy, but using this sling is like playing an original Nintendo on a modern flat screen TV.  When the LCD TVs first started coming out, anyone connecting their old Nintendo experienced an input delay.  A button press on the controller was just slightly delayed to the game reacting, so all timing was off.  This sling is kind of like that.  The release time is just a fraction of a second before it is with a normal sling.  It's way easier to get comfortable with the timing with a long slow rotation over a small fast one.

Thanks for the input.  Maybe next year will be a heavier weight, a decrease in overall length, and a decrease in the proportion of the secondary release length.

Title: Re: Compound sling vid
Post by Curious Aardvark on Nov 11th, 2019 at 4:19pm
yeah, I never said it would ever work - just trying to sling paintballs.
I think the heavy weight needs to slide, in order to impart energy to the final missile.

There is a video on here somewhere of the original one marius made.
I believe that used  a sliding weight.

Would love to know what happened to him. 

Title: Re: Compound sling vid
Post by joe_meadmaker on Nov 11th, 2019 at 5:35pm
I agree, I think the sliding weight is a good idea.  I know Sarosh used that in his too.  I ultimately dropped that because I couldn't think of a simple way to do it while still having a one-handed sling.  I'd love to see the video you mentioned.  If anyone comes across it, please post a link.

Maybe before doing another re-design, I'll read through that long original thread again.  Now that I have an idea how things are working, there may be a new inspiration to be found.

the video should be in my forum backup (reminds me, need to do that again) I'll have a look with a proper viewing program. problem mis most of the videos and images are assigned random numbers for names. So you can't just do a name search.

Hmmm... yeah the sliding weight makes a lot of sense.  I’m going to have to think about this more and see if I can come up with any ideas. I definitely think the ring sling could be adapted to a slider.

Is the staff sling a compound sling?

I would say it uses the same basic idea.

no because it's one handed and resembles a throwing motion.compound sling in function resembles the whip more
staff sling is usually 2 handed and motion resembles an axe/hammer strike.

staff sling better be light and have little mass on the tip Compound sling needs all the mass on the "tip". You wouldn't use a hammer as a staff sling or would you....

I think it works similar to how a compound sling unwinds but it’s only half a rotation, you can’t twirl it past the staff so it’s kind of a half compound in my eyes.

Still need to make a staff sling out of a fishing rod.
