Hi guys!
I'm from Sanremo, Italy, but i work for the University of Siena - Arezzo (in central Tuscany, about 450km from my hometown in western Ligury) where i attained a Ph.D. working on the production of printed books from XV to XVII sec.
At the same time i enjoy myself studying ancient weapons and warfare with a collegue and friend of mine (a madman from Turin, clearly resembling a nordic warrior, but i'm sure he is also in the lineage of Attila   ): we basically focus on the european middleage period, although from time to time i feel the needing of expand my horizon and look to other ages and peoples.

I found this forum and the site slinging.org about one year ago, and keep on lurking your conversation because i was really caught by the sling: construction, use, effectivness in war and hunting, and so on, and i really wanted to deepen my knowledge about it... and yes, clearly i was eager to create mine and use it! (my girlfriend says i'm halfway between Indiana Jones and MacGyver... every time working to an armour, a knife, a bow when i'm not trying to understand some crampled parchment from XIV sec. or to retrieve an old and dusty book )

I created my first sling about six months ago, now i'm about to start the... mh, i think it's the eighth  

It will be my care to share as soon as possible photos of them, as of ammo i use, but i can anticipate that i worked with various commercial fibers (cotton, hemp, linen, sisal, polypropylene, nylon), and i gave a try to make homemade strings made from broom: in Italy we call it "ginestra" and it's really common in ligurian undergrowth, and was used from local textile industry until '40s.

thanks for the welcome, sir
I made a post with a few slings of mine: they are not absolutely "state of the art" pieces, but i wanted to share anyway http://slinging.org/forum/YaBB.pl?num=1172017416/2025#2030

Alas, in the photo there is anything made from broom, because i've made only a sling from such material and i left it in Arezzo (now i'm in Sanremo for a month). Anyway, i'll try to made at least a piece of cord to show you, as soon as possible (the method to obtain the fiber from broom requires, inter alia, a long immersion in water and implies a definite smell of rotten vegetation, so I'll have to proceed in a proper place, and not in my apartment )

Welcome from an exiled tedesco in Wales, silme!

I would have never thought about using broom. Sounds very interesting. Please keep us informed about the results.
