It's all right Marc - we just thought you had a stutter; not a broken spellchecker Grin

Staffslinger,

does the Latin saying in the bottom line of your maikls mean "If slings will be forbidden then only the outlaws will have a sling"?

What he said.  David that is.  I thought it was apropo...  I'm going to translate it into other "appropriate" languages - Philistine Grin, Greek, Persian...

Another one that would be fun to translate would be "You can have my sling when you pry it from my cold dead fingers."

Slings don't kill people, stones do.

well yeah, I suspect you're the only one who didn't realise this -  lol we all have bad keyboard days.

Interesting looking sling though.
So with the shaped glandes does it help in any way ?
I'm guessing it might also be good for golf balls - cut down on the spin maybe ?
Like slinging a knuckle ball ?

I was thinking about golf balls when I was up on the stack today. anybody know th eweight in grams of a golf ball. I was supposed to be in the office this week but I'm back in the field so I haven't had a chance to get out and try this sling with some egg shaped lead sinkers I picked up. Golf ball might be a bit big, but I'll try it and see what happens.

Could, but the point is to try and stay as close to the original as possible, until we learn what it can and cannot do. Once we have that baseline then we can start experimenting.

We have a very unique sling design here, lets see what it can do.
as I mentioned in previous posts, this design may have something to do with delivary of shaped ammunition, but we won't know until we put it to the test. Or another possibility is maybe the experts got it wrong and it's not a sling, but a bit off of something else that rotted away.

Tried using golf balls in the Gdansk Sling. Didn't work, they kept rolling out in the windup stage. My guess is that they were too big. From my notes the diameter of a golf ball in SI units is 9 cm.

I also tried some egg shaped lead sinkers. I had two sizes available. The first weighed 13 grams, the second set weighed 57 grams. Probably need to get the length and width in SI units.

I had the opposite problem with the 13 gram (3/4 oz) sinkers. They were too small. stayed put during intial windup but during the release stage they were real erratic during the release. By this I mean they would either release early or late. They definately wouldn't release when I wanted them too. I think thier s

I tried the 57 (2 Oz.) gram sinkers next. First set of casts I tried orienting them point first through the pouch. Lets just say this wasn't real optimum and I have another slinging horror story that involved a close call.

The next set of casts involved laying the sinker so that the short axis was directly across from the thongs that attach to the pouch and the long axis facing the direction of the cast. Yep that definately worked. Sinker flew like a champ point first and impacted on the ground that way. I even managed to recover it a few minutes later.

I didn't measure the range. The main reson is my back porch is on a hill and my back yard slopes down then starts climbing back up. Net weekend if I can get to the river when it is way down I will try slinging th elenght of it and see what kind of range I can get with the sinkers.

Casting style was Byzantine, might also try underhand with it as well.


Ok here is where things start getting intresting. so far preliminary testing shows that this sling will work, just need to fine tune the ammunition source. Based on archelogical evidence we know that early europens, Say Neolithic to Bronze agish seemed to prefer ammuntion in a wide weight range. The Red Crag Artifact weighed in at 0.5 ounce (9 grams).In the Journal of the British Archelogical Association (1864 Pg 75) Two excavated sling stones are mentioned. The first weighs 7 ounces (150 grams) the second weighs in at 12  ounces (300 grams). And this is just in the British Isles

 We do know as well that the Greeks and early Romans used lead glandes. However no known reliable reference has mentioned the use of lead bullets in the medieval period . In the case of this sling near the end of the 10th century. Are we missing a valuable piece to this puzzle? Is this sling design optimised to actually use lead ammuntion?

More study is definately needed.

Hi Marc,

I also have a feeling that the experts got it wrong and the item is not in fact a sling at all. I found the original Polish article fairly unconvincing and "bitty". It had the feel of an assignment knocked together the night before it was due and by someone who was not at all comfortable with the subject, casting about for quotes to give it a bit of credibility.

Regards,

Aussie

Yeah and the article by Michal Gradowski not even touching on it's unique nature definately is odd.
I fully agree about the Krystyna Nadolska article. I thank any of us on this forum could have done a better job than that in half the time ;( But welcome to academics.
But the kick is the thing does sling albeit some ultra specilised and tuned ammunition..............
Anyway lets see what happens, and who knows get enough experienced slingers looking at it and maybe we can figure this bleeping thing out Smiley

Yea I'm trying to be optimistic. Now ifI can just get the Gradowski article to cut and paste into my research paper Sad ( yep I'm trying to work on it before I hit the hay)
Anyway hope you are staying cool Aussie
