Hello from Minnesota
Jul 24th, 2023 at 11:31am
 
Hello from Minnesota, USA. I知 new to slinging as of last November; an archeologist friend of mine got me interested when sharing some of his finds. Now I知 working with him to learn and write about how slings were used, specifically by Roman auxiliary troops, in the first century AD.

To better understand the art and science, I致e made a few slings, some out of paracord and nylon webbing for the pouch, and several in the Balearic style out of sisal and hemp; they are getting better but not photo-worthy yet, based on the craftsmanship I致e seen on display here! I知 working my way through the tutorial section, so looking forward to making the next ones and raising my game a little.
I知 also practicing slinging, but will continue to stick with tennis balls in the interest of safety for those nearby.

Current curiosity: very interested in the external ballistics of sling ammunition, particularly bi-conical or ellipsoid shapes. I suspect that the act of slinging imparts spin to the projectile along the long axis, stabilizing it in flight, and that it flies point-first, much like an American football. This attitude in flight results in less aerodynamic drag (as compared with a sphere), increased range, and greater penetration at the target.

I値l continue searching on the forum, but if anyone has related information that would validate (or correct) this view, such as slow-motion video of ellipsoid sling projectiles at release or in flight, related data or charts, or other links/pointers that would pass muster in an academic paper, that would be super helpful.

Looking forward to learning from the many talented and experienced slingers here!

Welcome! I also got into slinging last November-ish. Tennis balls are great ammo.

Roman Auxiliaries... sounds interesting Smiley
Sling ballistics are a great topic for a discussion here.

Once, Toivo and Eino were building a house, but as Toivo worked, he would occasionally throw a nail over his shoulder. When Eino asked why he was being so wasteful, he said, 典he heads are on the wrong side! Eino looked at him and said, 添ou dummy, those are for the other side of the house!

Welcome from Pennsylvania!

The biconical projectiles you're referring to are commonly called glandes in the slinging community.  And you're correct that with this type of projectile, a flight similar to an American football is what's desired.  Getting a clean release of the projectile with perfect rifle spin is the goal, but can be difficult to do.

Hello from Florida.  I'm new as well and have download much of the information on the forum.  Great material.  Your focus is much more technical than mine.  I just want to hit the broad side of a barn - so far anything in front of me is absolutely safe.  Thankfully, I'm using tennis balls with a pouch PDF design I downloaded from this site.  Please post more as your adventures continue.  Mark
