Lookls awsome and realy well made if it was UKSlingshots i would surely buy one.
I visit occasionally to make unrelated posts.
Welcome back, and great slingshot!
I have designed and made a new slingshot invention: A mechanical release that will revolutionize the butterfly shooting style but also be useful for any other style.
The device has a 360 degree rotating, self centering lock head that allows you to draw out as far as you like without twisting your wrist.
This way the biggest drawback of the butterfly shooting is eliminated, the cumbersome pouch gripping that limits you in terms of band strength.
Thorsten, a German butterfly shooter, showed us what a 5 kg (11 lbs) draw can do in a butterfly setup (30 Joules!), now imagine what a 15 kg draw will achieve...
Tested it with a super long Thera Gold set (7 kg draw weight at 160 cm draw). Pretty fast shooting!
Unfortunately it is raining very hard today so no chrony tests - will maximize that probably tomorrow. Let us see how much power the butterfly style can deliver!
Here it is:
My design can be made without welding, mostly from wood and a few hardware store items. The video contains a how-to part, so you can make your own one!
The "Butterfly" shooting style brings the power of slingshots into new dimensions.
With a "wingspan" of about 1,60 meters, Jörg Sprave can break the 60 ft/lbs (80 Joule) projectile energy that the US military considers as lethal for humans.
So what would happen if a guy with the arm span of Dirk Novitzki (2,30 meters) and the power of Arnold Schwarzenegger (in his days) could achieve with a forward extended slingshot, giving him a 3 meter draw?
To find that out, a new slingshot crossbow has been designed, with a total draw length of said 3 meters. A trigger based locking mechanism allows a normal person to cock and shoot like Novitzkenegger!
The results are quite impressive. 75 m/s with a 36 gramm, 19 mm lead ball (576 gr, .75"). 102 Joules, over 80 ft/lbs!
Here is the video (the last one from the old house, my wife packs the boxes right now):
Haha I watched the video on youtube already, that is awsome!
I think you should make a semi auto slingshot next...
Here is the first video from the new garden!
I tested the impact of 16 mm lead (made with the Bellsofhythe 12 shot mould) against the ubiquitous coconut and then on to a supermarket duck, still in the plastic coat.
The ammo went through the duck, even lengthwise, breaking bones and shattering through tissue. The duck had all of the innards still inside, in another plastic bag, which got penetrated as well.
I used my strongest handheld frame (the "W) in butterfly (albatross) style, and also the Novitzkenegger 3 meter sling-crossbow.
Sorry for the wind, we are having a very cold and windy August, feels like the fall is here already.
whats the guy that borght you old house goanna think about then he sees a tree with thousands of balls in it.

My metal working tools haven't arrived yet, so I made a wooden slingshot today.
It is the first boardcut "W" design, and it's an ergo shooter! I used the clamp-on method so I can rearrange the bands quickly for butterfly or normal shooting (pics show butterfly length).
I carved the finger grooves first, then I cut of a slice and laminated it to the handle of the boardcut. This way I was not hindered by the fork arms when I took the rasp.
I used the clamp-on method also because it gives no handslap and I like the clean band attachment.
No varnish, just wood stain.
It is a very good shooter, and perfectly safe due to the width of the fork arms. It's not exactly beautiful, but heavy duty!
I must say that this slingshot is pretty darn effective. I think I found the ideal band dimension for the 16 mm lead balls I made with the Bellsofhythe 12 shot mould.
I tested it extensively today, in butterfly of course. I leaned a wooden plank into a corner of my stone wall in the garden. The ball flew right through the plank, hit one stone corner, ricochetted and hit the other side. Here is what it looks like now (compared to the original condition:
Note that I am using lead from car wheel weights, picked them up for free. This material is much harder than the lead used for muzzle loaders, in fact if you use it in a muzzle loader it will damage the rifling in the barrel.
Can a slingshot break bricks?
If it's the right one, yes it can! This video compares a store bought Trumark slingshot with the original bands against a genuine Jörg Sprave "W" slingshot, rigged up with dual Thera Band Gold bands. Both slingshots are tested against a melon, a small pumpkin, wooden planks and then against a modern brick. The hits are recorded both in real time and in super slow motion.
Of course the homemade slingshot, used in Butterfly style, outperforms the Trumark by far - and yet the Trumark did a good job shooting the heavy 20mm steel balls.
So now we're going to test this brick... *knocks it on head*
I wanted to do design a frame that works well for the butterfly style.
- Low, wide fork for little wrist strain and fork hit prevention
- Mid-size (not as huge as the Monster)
- A big palm swell (found out I like palm swells)
- Protection against hand slaps (seems those always happen on OTP butterfly shooters).
I figured that the "W" would make the frame too big. So I used a length of flat steel I salvaged from the scrap heap and attached a wooden grip and wooden fork arms, all with solid metal screws. I hammered nuts into the fork arms, and sealed the holes with epoxy putty later.
Then I cut a piece of leather and clamped it between the handle and the screw.
It looks like a cutlass handle now - so I had a name for the design.
This is as basic as it gets, a full blown hammergrip style frame. The last picture shows it rigged up with really thin butterfly bands, superfast for lighter ammo. Without the leather protection, handslaps gallore.
It is a superb shooter, probably no beauty queen but the king of functionality.
And here is the video:
Have added Reddot sights, and also I demonstrate that the design is safe, no danger to be hit by the returning fork.
The mounting rail is made from a piece of wooden board, with a cutoff part of an old metal saw blade as the rail. Works like a charm.
The Slingshot Channel reviews the only knife that is also a slingshot: The "SYRVIVAL" by the German knife maker company "Blade Systems".
The knife is a tactical beauty in itself, made from high tech "Chipper Steel" and with an splash etched finish. It is super sharp and the canvas micarta handle is really perfect for a strong grip.
The sheath and belt system is up to top military standards with the Tek Lok belt clip and the Blackhawk Serpa QDS adaptor.
The Kydex sheath contains a whetstone to sharpen the edge should it ever become dull.
A fire starter kit can create enough sparks to start a fire at any time. (People pointed out to me that I am using the starter kit wrong in the video, have to slide the steel along the rod.)
The highlight and specialty of the "SYRVIVAL" is the slingshot attachment. It can be mounted to the grip of the knife in a few seconds, and then it turns the knife into a very effective hunting cattie. The original "Fish Hunter" bands that come with the product are amongst the most praised bands available today. They can deliver 27 Joules of energy, more than most air guns and in the same league as hunting bows.
The starting price for the knife is 305 Euros, the complete package with all the bells and whistles cost 508 Euros. Not cheap, but well worth it - a handmade beauty that is as efficient as it looks.
Here is the video:
