Slinging tutorial - How to control spin and curve IronGoober 2022-02-06 | I describe how a sling projectile curves due to spin during flight, how it happens and how to change the way it spins (and therefore curves). I then demonstrate the effect, and lastly show slow-motion video of the effect.Please see NOOC and Catch This' video(s) that demonstrate the spin on release using these same principles.youtube.com/shorts/JzpwUyyrU4E?feature=shareyoutube.com/watch?v=4QEbyCOaZg4youtu.be/ajzuWrYfrfk
Experiments with firing clay glandes in a microwave IronGoober 2024-09-18 | Experimenting with using a microwave kiln to make fired clay glandes in the microwave in under 2 hours with commercially available clay. (Terracotta)Total energy cost is around 2 - 3 kWh. The clay was fired at a temperature higher than recommended (1150°C) which is likely why they were shiny and looked glazed.@0:00 Intro@1:37 Microwave kiln@2:22 Setting up@3:40 Recipe@5:45 Expected temperatures@9:55 Power level 2@11:49 Power level 4@14:30 End of Power level 5 (HOT!)@15:45 Taking the glandes out@22:07 Drop test@23:31 Melted clay and final thoughts

Archaic Arms - slow motion, 41 sling (960 frames/sec) IronGoober 2024-07-16 | This is the form that I strive for when throwing for distance...massive shoulder-hip separation, good scapular retraction and good arm lay-back.
Slinging - Get a hit, move back 10ft challenge #3 (30min) IronGoober 2024-05-31 | Hit a 'diana' (50cm bullseye) and move back 10 feet (3m). See how far you can get in 30 min or an hour.slinging.org/forum/YaBB.pl?num=1585792415/90#90You could also do 2 points to move back (2 square hits(120cm), or a diana)Editing error: 10 shots at 100 ft, 3 shots at 110 ft#shepherdsling #slinging #throwing #slingshotchallenge
Slinging - More efficient throwing with a high wind-up IronGoober 2024-05-22 | If you see where my hand goes on the wind up, it is low in the first throw and progressively higher, where I'm trying to get my hand up and behind my head before I start the power stroke (acceleration of the projectile). The third throw looks more efficient (and is!). This is because I have lengthened the power stroke, or lengthened the distance over which I am applying maximum force to the projectile. This is why it gets more speed.

Drills for slinging more efficiently IronGoober 2024-03-16 | I discuss some simple drills for slinging more efficiently (more velocity with less effort).
Sling Types and Grips IronGoober 2024-03-11 | I talk for too long about different sling types, reasons you might want to use them, and different grip styles and reasons you may want to use one over another. I also emphasize the need to change things up and try new things when using the sling, ultimately making your brain more adaptable and become a more proficient slinger.I tried to keep this concise, but failed miserably.@0:00 Introduction/title@0:05 Sling Types (Pouch)@0:45 Sling Types (Strand)@1:00 Reasons for pouch types@2:50 Reason for strand type@3:55 Reason to strand type (speed)@6:15 Sling Grip Considerations @6:30 Finger placement@10:00 Release cord grips@12:10 Unconventional Grip types

I draw some tentative conclusions about the effects at the end of the video. More data to follow (eventually...)Here is the data plotted in more detail. slinging.org/forum/YaBB.pl?num=1703086191/0#001 Camera films at 960 frames/sec and is a 'Sony ZV-1'

Sling Dodgeball! - With the Bay Area Slinging Club boyz IronGoober 2023-11-26 | Sling dodgeball with tennis balls. We all wore safety glasses and weren't slinging hard. This game is definitely some of the most fun I've ever had slinging.

100 m target slinging - into the sea IronGoober 2023-10-22 | Here I was slinging at stone targets out in the sea sitting around 105m (estimated from Google Earth) using a 28" sling and random stones (very, very nice random stones).Featuring Archaic Arms and Acroballistics.AA had a total of 12 hits on the day (including a target at 175m).Acroballistics had a left handed hit, but the camera died.I had 3 hits.
IronGoober, ArchaicArms and Acroballistics sling stones at the beach (Slinging 960 frames/sec) IronGoober 2023-10-18 | Some fun in the sun at the beach!if you notice my two throws, the lower speed throw had much worse hip/shoulder separation and my rotation started much too early. In the faster throw I stayed counter rotated for much longer (but it still isn't very good... see AA's throw!)

Sling velocity training (up to 70 m/s) - Tennis balls (short version) IronGoober 2023-07-30 | Training for distance throwing with different slings and a tennis ball. Tennis balls are good training tools because they don't travel far and have a ton of drag, so they are hard to get up to high velocities.I had an iPad out, but you still can't quite make out the readout. Here are all the readings for this short version: (entire session here: youtu.be/OsXiTmVzG-k)31" sling:60, 62 m/s38" sling:67,68 m/s44" sling:69, 70, 70 m/s44" sling, upward:69, 69, 70 m/s

Slinging tutorial - Increase your power-stroke to get more velocity. IronGoober 2022-10-05 | Just a quick discussion and demonstration of using a larger power-stroke to get more velocity.
Slinging at lake for Distance IronGoober 2022-10-03 | This is video is mostly for my reference, but in case anyone else wanted to see some distance throws, I put it up.Chuckin' stones with a 1m long sling. Just past the first patch of lakeweed was 300m (i.e. "the white dots" which were a couple of rocks sticking out of the water). The second throw was the best distance, I'm guessing 320-330m. It has 7.6 second of hang time. This corresponds (most likely) to a sub-optimal release angle of about 35°, which is consistent with what I've seen from my throws previously. Simple trajectory models show that an optimal release angle of ~40° should get about 9 seconds of hang time and another 10 - 20 meters of distance. These were egg shaped stones ~42g each.Again, this video just demonstrates that with distance slinging, speed is not king, air-resistance is king. Minimizing it, somehow, is the best way to get distance.
Slinging tutorial - How to adjust your aim IronGoober 2022-10-01 | I babble on for a few minutes about how adjusting your power stroke timing may be more beneficial to change your aiming point than trying to adjust your release point timing.Demonstration: @0:45 @1:45 @2:22Diagram and discussion - @3:40Note: this video may not be very helpful if you are very new to slinging... but come back to it in a few months, and I bet you'll find this video useful. Credit to Morphy on slinging.org for this idea.Also, could I have fit the word "consistent" in any more?
340 m throw with a sling! IronGoober 2022-08-20 | I use a 41 inch (1.04m) sling to throw a 58.6g concrete gland 330+ m. Most of the video is me looking for the glands...they are hard to spot. I did it in one take to prove that a 300+ m throw with a sling was possible.@00:00 intro@1:15 The throw: @6:47 The find: @8:11 The ranging:
300m! 160mph sling throw (72m/s), 75g stone IronGoober 2022-07-26 | I found a stone at 302m. I think this was the throw that put it there.
FX Chronograph testing - Sling velocities 65 m/s (146 mph) IronGoober 2022-06-27 | I use a 34" sling (2mm UHMWPE, aka dyneema and leather) and 50-60g stones (weighed).After the first throw, I thought I heard (187)...but it said 137. So that gives me more confidence this thing is correct.Also, I ranged it, it's 250-260 m across the lake and a 22m drop (elevation loss).Update: A side by side comparision with the Pocket Radar showed that they were within 2 mph of each other with a thrown tennis ball (~60mph) and within about 3mph when I was slinging a tennis ball over the top of them (~105 mph). I'm satisfied this radar is accurate within 1 m/s.
