I must think about wheels for glandes :D

Jurek

Great idea, to throw on a run way, were you able to recover all you threw? What did they weigh and of course, how far did it go? Looks like it wasn't traveling in the point first spiral, going by the impact marks on the side.
Oscar

Wow!

That would really hurt the face huh? I got to make me some of those babies!

The last weekend I only reconnoitred the near aerodrome due to future range tests. However, I had two residual glanes, so I slung them along the runway ad hoc, without any warm-up. I recovered only the one of them. The second one most probably was bounced out of the runway into the grass. That one went some to the left, and hit near the edge of the runway (50 m wide, at a guess). I heard its knock. The first one I have recovered easy despite having no observer nearly the fall zone.

The weight of the glande was almost 120 grams. I didn't measured precisely the distance. I measured only the one conrete slab and next couted them. From the calculation I have got the range 388 metres.

One of the glandes flied with wobbling and noise, one calmly.

Jurek

Yurek,

Have you ever shot down an airplane with one of those glands while at the airport? ;D

It was the military airport in the past. Nowadays that large terrain is partialy used by the aeroclub and different buisnesses. That day there wasn't flights, alas :( If so, I would try to hit one of them, sure :D

Does Poland have good slinging weather in the summer?
Tennessee is VERY hot and humid!
Johnny

I can back Johnny up on that one.  It IS hot and humid in Tennessee during the summer.  It rains about every other day.  

A few generations back, my ancestors lived in Cleburne County. Do you live anywhere near that area? Any good rocks to be found in ole rocky top?!
Johnny

Yurek,
That is a very impressive distance! What length sling do you use?

I believe that lead glandes are much more accuracy and have longer range than Stones specially in the windy days. What is your opinion?

Trzymaj sie! Jezeli znajdzie sie okazja to sztrzelaj do jakiegos nisko latajacego samolotu a potem opowiadaj nam co sie stalo :D

Johnny,

I live in Blount county.  It's about 3 counties south of there.  There are plenty of rocks here.  There's even a river near by if I want some flat ones.  

longwinger,

I used the 50" long sling. Normally I use shorter ones, they are easier to manage. That long one I use for longer range shots.

Johnny,

We have the temperate climate, so generally that is ok. Sometimes there are heats too. It is't good weather for slinging, indeed,  specially on a runway :) But this summer is cold and rainy until now.

zeluiz,

Yeah, you are right. Lead ammo work much better, no doubts. It is pitty that lead almonds don't grow on trees :) I usually use stones as the ammo, their quality is mostly average. With lead glandes I get considerably longer ranges. I didn't sling a lot lead missiles as far, just a few dozens. I only used them for distaces, but I'm sure they are more accurate too. The wind have a much smaller influence on the glade trajectory, because they are more dense than stones, what gives a better balistic coefficient.

:o Nie wiedzialem, ze w Brazylii tez mowia po polsku ;) Milo bylo przeczytac tutaj, te pare slow we wlasnym jezyku. Nie bede mogl w nocy zasnac, jak mi nie zdradzisz skad znasz polski  ;D Pozdrawiam i obiecuje informowac o kazdym trafionym samolocie :D


Jurek

Yurek, I was going to ask, how do you recover lead glandes??  I'm preparing to gather materials to cast some myself ... I'll keep a few back as show pieces (I do Roman re-enactment and will most likley create glandes with authentic Roman inscriptions) but I MUST sling some lead!

Mithras,

That glande on the pcture is the first one I have recovered. Before I lost all the glandes, and only knew an approximative points of landing from relations of observers. On the runway there was no problem with it. But as I said above I slung only two glandes. One of them was painted with orange acrylic dye, which has chipped off almost entirely. Soon I will cast some amount of new ones. Yeah, slinging lead is something different than slinging stones, they fly as if they have own power. Good luck!

Jurek

Wow!  ;D

Finally evidence to all the non-believers that slings have superior range.

The only thing I had trouble understanding is ... I am unable to see what the picture is. What is that picture supposed to represent? It looks blurry on the sides, but clear in the centre.. and the centre of the gland looks like some bad fractally-generated 3d-terrain made in Bryce. I'm not saying it's false, just saying how odd your photo is, that it makes me see such strange qualities in it. :) I am in no doubt that it's real, it just looked so odd. Could be the photography itself.. or something.
Try making a photo of it in an indoor well-lit surrounding.

John,

That range doesn't seem to be as impressive as Larry Bray's and David Engvall's achieves:

L. Bray - 437 m with a stone
D. Engvall - 473 m with the special dart.

The above picture isn't a photography. This is only the scan of the tore off surface of the glande. I used the flat CIS scanner, that have a low sharpness (focus) depth (~3 mm) and the black background.

Here is the picture (from my classic camera) with the glades casted in the same mold. This picture was published on this forum once before.

Yurek, you said you know the approximative points of landing for your lead glandes.  I was wondering if a metal detector would assist you in locating your glandes.

Yurek - even more questions!!! I'm currently making clay moulds for glandes and its a bit of a fiddly business. Who do you produce such perfect castings?????

ZaQ,

That place is very difficult terrain for finding glandes but good for slinging and have a shelter for an observer. A metal detector could help, of course, but I don't have that one. There was railway line before, so there is a lot scrap-metal in the ground. Some poeple seek that with metal dedectors.

Mithras,

I molded these glades in the mold made of plaster of paris. The models I rolled of the hot-setting plasticine paste for children. Just a simple but time-consuming technology, require a bit care.

Jurek

Just wondering about the landing that your lead friend made  on the runway. On hard surfaces, such projectiles bounce and roll quite a bit, making it hard to determine an accurate range. Maybe a lead glande deforms on landing and doesn't roll as much? ::)

This is my first recovered glande, so I'm not an expert on these deformations. But lead is very soft metal and that undisputed fact explain that kind of damage. The first imapct enegy makes the plastic deformation and heat, so glandes don't bounce immediately but in this short time they slide on concrete (what wipes them and additionally slows down). When the deformation stops (due to lack the kinetic energy), just then the glandes start bouncing but not so very mightly. Just my theory.

This glande was a bit deformed and had a few not large bruises and rasures on the other sides. That one lost almost all dye during the first knock. I heard that knock clearly, so hidden in different positions observers shouldn't have a problem with determination where to start the search for the impact point marked by the peeled dye and lead.

Soon I will do the more accurate testing on the runway.

Jurek

Today I slung the lead glandes on the runway again. Their "injuries" were similar. They didn't bounced far from the impacts points. All ones mostly had the one wide flattering and a few (some 1 or 2) smal razures or bruises. Looks like they "sticks" to the concrete. The surface of the big flat distorsion of some glandes had marks of frication, but some of them were only crushed,  had a texture of the concrete (I think it was glades that I slung more high). I was amazed because one of the glandes didn't lose the paint cover, even the flattered surface has kept the paint but that one was darkened from the high temperature.  Looks like it had sat and stayed in the impact point ???

It was really nice slinging, couldn't stop it. Recovered glandes I slung again an again, until I could find no one of them due to dusk.

I'm very happy because today, first time I noticed that I'm able to sling a granite stone (used them for warm-up) over 400 m!

Jurek,
That is just incredible, four hundred meters with a rock!!
Using a long sling like you do, is more than one revolution required to get up to speed?
Is wind a factor when you are slinging, or is your area fairly calm?
Oscar

400m with a granite stone ?  :o With what slinging technique did you manage to do that ?

Quote:

That is just incredible...

Oscar I know... few mounths ago I thought the same, until I had seen Larry Bray's result from the 1982 year - 437 m.

Most often I make the single initial revolution (sometimes the more, but it doesn't seem to be a big factor) and next the springy lash. Sometimes I use the overhand throw and sometimes more lateral, I'm not decided which of them is more efficient for me, seem to work similar. Yesterday I was slinging not long before the dusk and the wind had calm down after the windy and rather rainy day, so I heard almost the all knocks.

Consider I declared to take the try beating the GW Record this year so I simply must to reach similar ranges ;) No retreat way :)

A long sling is more difficult for the efficient manage. If one haven't a practice with it, most probably is able to get better results with a shorter one.

Maybe it is incredible, or not. Anyway I have decide to share it here. There isn't any better place for doing it, right? Besides, maybe somewhere there is a guy who thinks - Only 400?! That is  poorly! - Who knows ;)

I will hold my thoumbs hard for you, Jurek!!!


Ulrica

Thank you Ulrica!

Your words make me twice happy!

Jurek

Congratulations, Yurek!  I see you are determined to beat the Guiness record this year. I´d like to see your training and advances there in Poland as a member of your actual support team  ;D, but one have to be content with only a virtual observation and support. Give us details of your progress, technique, etc. It will be nice to share your experiences and encourage you  :D

Are the lead glandes finally permitted like projectiles?

Thank you Hondero too. I would be honoured having you as guest and adviser in my home :) I have to struggle with my mistakes alone, so all advises are welcomed. But there is a problem with the virtual observation, because I haven't suitable hardware for making digital movies, while we all know that a picture says more than thousands words, especially in my awkward english. I desribed my technique sometime, but no desription can deliver all niuanses, what is even not easy in own native language. I think that I have a bit modified and improved that one and additionally started to use more underhand one during last mounths.

I'm presuming that since David Engval used the lead darts so lead glandes should be premissible with no problems.

When I make the official try I will got some movies and pictures and then will share it.

Jurek

the support team... ehh... old good times :'(
