Jurek,

Your confidence in my ability is flattering.  It sounds like you are having great success with your throws also.  I wish you the best.  I bought a mold for 2 oz egg shaped fishing weights about 10 years ago and have cast several hundred lead projectiles.  I have thrown a few and they flew really well.  The rest are sitting out in the shed awaiting their moment of glory.  Smiley  I should maybe file the ends to sharpen the point a little, they are quite blunt but similar in shape to the rock I threw, but with a much smaller frontal area.  I have improved my slings using smaller diameter cord and smaller pouches.  Less wind resistance prior to release.  We still have a foot of snow on the ground but within a month or two the weather will be nice and the reservoirs will be thawed so I can see where my throws land.  I prefer throwing over/across lakes to better judge distance.  Do others do this?

Larry,

I'm going to try. We have winter too, and it is not good seson for such play. I tried 100 and 120g (3.6, 4.3 oc) lead ammo. Really, I surpass Davids's range with them. I have put the pictures of these glandes and slings here, maybe you have seen it. I have made the mold of plaster of paris. The ranges were "measured" by the observer who was hiden close the aim zone.

I don't know whether I shouldn't resign, since you are going to do it Smiley))

I like slinging into water too, but there are too many people around usually. So I often chose a more solitary places. I also wish you the best. I hope we will be in touch, and you will tell me your ranges Smiley Maybe I beat the air Wink

Larry, I like throwing over water, too. I get instant feedback about the throw.

Yurek, would you please repost your glandes pictures here or email them to me?  I'd like to see what you came up with. Dan

Hi Dan;

Here can you found the lead glandes that Jurek made:

Thanks, Ulrica, I forgot the search engine, which works well on this forum.   Grin

Larry, Don't sharpen those points just yet. I've been thinking about the glandes shape. Here is my thinking graphically. If you can't throw the proper airfoil, then the final shape will be the best compromise, based on my limited knowledge and experience with air/hydrofoils. Dan

The funnest scenario would be several of us chasing the record, leapfrogging each other and pushing it up to new distances previously thought out of reach.  Records are meant to be broken, right? 

Dan

The fourth shape (symmetrical glandes) from your post is very similar to the profile of the record rock but the rock is much larger.  Your image is very near to actual size for my lead pellets except mine are slightly more blunt front and rear.  I need to refine the "well shaped forebody" somewhat by modifying my mold.

Dan, have you realized that your NACA n.1 is just the shape of David Engeval missils? I think that if David has used his atypical device and method of launching is because he did not find a way to lodge this type of optimal projectile in the pouch of a sling   Roll Eyes.

Larry,  If you like, copy and print that image to make your shapes. I can also provide you with a CAD file if your university has a CNC mill to cut the molds. Wouldn't that be sweet!? 

Hondero,  Or, David's dart is close to my shape.  Roll Eyes  LOL!

Good design is good design! Actually, the NACA shapes go back to the 1920's or so. Of course now the organization goes by its new name, NASA.

I came up with my shapes from practice, experience, and common sense.  The glandes shaped stone simply flew the best for me so that is what I used for the record and what I tried to duplicate with my lead pellets.  These were some of the "secrets" I alluded to in my first post.  Don't I feel silly!  You guys knew this stuff all along!  But we're among friends here, right?

[quote author=Yurek link=board=1;num=1076973351;start=50#57 date=02/22/04 at 16:48:26]Dan,

The sling is to be made entirely of leather..." I suppose that GWR rightly tries to restrain the "technological race" in that category and the rules are new.

Well... that is only my opinion, But I think that forum is the bigest sling experts community of the world and it is the best place for creation and carrying rules to GWR. I'm curious of your guys opinions and Larry's one too.
]



The new regulation of the Guinness sincerely seems to me inadequate and lack of knowledge of the sling. The integral leather slings are not indeed the best ones and estatistically they have been used much less throughout History than those of braided fibers. I think that if we considered ourselves as a group with some authority in the world of the sling we could establish a minimum regulation on the weapon, since we have commented. My idea on the matter is that the sling is a well defined weapon, that has lasted in its initial configuration from prehistory to the present time, and that indeed its design and functionality is the one that we, lovers of the weapon, must make an effort to conserve and transmit.

Nevertheless, the incorporation to that traditional design of all the advances in the technology of the materials must be allowed since it results in benefit of a greater performance of the weapon.

As a first epigraph of a possible regulation of the sling it would be necessary to write up a clear and precise definition of it.
It would have to be described the existence of a pouch to lodge the projectile, of any design and shape, but obligatorily with functionality of only support, not allowing other ways of attachment of the projectile, like hooks, spherical boxes or tubes with opening capacity to release the missile, etc. Rigid structures or of articulated parts would not be allowed either.

In regard to the cords,  it would be necessary to mention the existence of a cord of permanent attachment at the hand and another one of firing, that when loosen allowed the liberation of the projectile in the pouch. Handles could be allowed (already they were used in the antiquity also), but  firing gears included in them would not be allowed. The materials could be organics or synthetic, flexible, even metallic cable, but never rigid rods of any material, nor articulated pieces.

In regard to the launching, it would be allowed any movement able to provide kinetic energy  to the projectile, and any style of turn around or simple movements of propulsion. The projectiles would have to be massive, globular more or less extended, with a ratio length/width non superior to 3/1. Composed forms are not allowed, with fins, stabilizers or other complements. The material could be anyone, and of course heavy metals, of long historical tradition. The projectiles would have actual capacity of destructive impact.

Well, sorry for the long message, but these are only some minimal  and common considerations on the matter. I think the sling has not followed the way of update of the bow, and must it have done. Does the bow hides Freudian reasons which the sling lacks, and for that reason its much more appealing? Or it´s simply because it is easier to use?

Larry,

Yeah! You are absolutly right. It becomes more and more interesting and exciting now. I'm curius whather someone else is going to set up the new record.  Anyway, gentlmans, who starts first? Cheesy Wink

Dan,

Probably, you have seen those pictures, since Ulrica gave tips for you. But I have put the pictures here, anyway. They are on-topic here, I think.

Your compromise shape make sense. My own ones I formed at a guess.

This is my forst sling made for the lead glandes. As you can see it is nothing "hi-tech". Just that one (+ 100 elongated glandes) let me to surpass David's range. I know it only from relations of my observeres and  I believe that they didn't lie Wink

...

Here is my second test sling and the lead projectiles. Alas, I don't know eficiency of that sling and the "balls" yet.

Please tell us how you made your lead glandes!
Your sling looks like it has loops half way between the pouch and finger hold, why?
Great work!

Hondero,

My point is similar to yours. I think would be well to get  coherent rules here and submit to GWR. Devices out the rules should be in other category. The situation should become clear, when someone surpass David's record with the sling which is compatibile with these rules. David's record should stay in THE SLING CATEGORY, anyway. I personaly recognise that one due to lack the clear rules before. But it would be good to restrain the "armaments race" in the future.

Johnny,

If I find more time I will try to desribe more exactly how I made them. The way is primitive rather. I formed the models of modeling paste and flooded them with plaster of paris in the box, in two stages. So I have got two piece mold. Next I made the drains.

I wasn't sure what lenght of the cords would be the best for me. I used these knots for adjusting a lengh of the cords.

Here are the pictures how to make that knot. That one is quite good for making a sling of single rope, too.

Yurek, Since you showed me your glandes, I'll show you mine!  Roll Eyes

39gram  (1.4 oz.) glandes with mold I made.  Based on what I've been reading here, I'd like to make larger and better shaped ones, too.
