Have made another version of my slingbow. This time, upon many requests, I did a tutorial video as well.

I have devised a home made arrow rest, using rubber (what else). Also, I set the rest far back to gain draw length. Then, I designed the "frame" in a way that armslaps can never happen.

The bow is entirely made from 12 mm and 19 mm plywood, with three screws to stabilize the weapon.

It is more bulky, but also a lot more powerful than its predecessor.

Made this on Halloween, so I just had to shoot at a coconut... penetrated both sides. With a field tip.

Here are some screenshots from the video:

The slingbow weighs 550 gramms (1,2 lbs), ready for shooting.

Here are the blueprints:

u like how your not only doing slingshots, ur mixing it up with bows also. good job

 

[Gandolphin]

Although your current works impress me,
I kinda miss the slingshots

 

[JoergS]

Gandolphin, it is just a phase. Been through the Beauties, been through the Chinese Loops, been through the Roller Bearings. Will be back to the basics soon enough. As always.

Beeing out on a limb is fun!

Hello,

very new and interesting project and nice shape.

May I ask you a question about the arrow you use: what is its Spine and Weight ?

Thanks

 

[baumstamm]

great craftsmanship, but it is big, much bigger then a "ordinary slingbow" is it werth the sice?

 

[A+ Slingshots]

Very interesting Joerg!!!

 

[JoergS]

I mostly shoot CF arrows, they simply last longer than wood or aluminum. 10mm spine, 25 gramm weight.

The size is bigger, but it shoots harder, the rubber lasts longer and it never hits your arm. Is it worth it? Depends on what you want. I think so.

Don't know why, but my youtube upload failed twice yesterday. Almost ten minutes, 700 MB... takes five hours to upload with my slow internet connection here.

Oooh, I see pre-tension! I also like the new and swappable rest.

PS/ You need to reduce the capture resolution to make smaller files, or get software than can scale video.

I can output in any resolution I like, and use any kind of file format. I am editing in I-frame only mode, full HD (60 MBit/sec). That would take days to upload, so I output in 10 MBit XVid Full HD.

I want my videos to look good on youtube, so further downsizing is not desirable.

Hi Jeorg what is the total weight of the slingbow ? btw it looks fantastic

Jörg,

On a related note, do you have any tips for people interested in recording and formatting/editing their own videos ?

For instance, what software do you use ?

 

[JoergS]

For instance, what software do you use ?

Well, I am totally biased, as I am the CEO of the company that makes the editing system I use...

One of the reasons why I started The Slingshot Channel was that I decided I have to experience the product like our end users do. So I had to start making films. But you need to have a real task, otherwise the conditions are unrealistic.

I always liked slingshots, and that seemed the perfect topic for my vids.

The editing product benefits from my video/slingshot hobby, I found several bugs and also got ideas about needed features.

There are many software and hardware products out there, it really comes down to what you need and how much time/money you want to invest. I really can't give you a recommendation here, I hope you understand.

Regards

Jörg

I suggest Virtualdub to shrink the AVI to a much smaller file size.

 

[ZDP-189]

I know next to nothing about video, but it strikes me as odd that it'd need five hours to upload what you can later stream from youtube in 10 minutes or less. Sure upload and download speeds differ, but clearly they seem to be converted from a big file to a smaller one. There must be some freeware out there that can do that on a PC. I get this problem all the time when my wife asks me to "just compress it so I can attach it to an email."

 

[JoergS]

No. The quality suffers too much. I do video for a living, guys, and I really know a lot about digital video and compression. 20 years of a career in the industry and a genius brother/partner... I learned.

Indeed I can only upload six times slower than I can download (rural Germany...). But that is not even the only issue.

When you upload to youtube in Full HD, they will convert your video into at least five formats.

1080, 720, 480, 360 and Apple (for the ipod/ipad/iphone clientel). If you upload in 360, you only get 360 and Apple.

So I could use a lower resolution and upload in a fraction of the time. Watchin a vid in 1080 has very high datarates, and many internet users have to preload such a vid as otherwise it will pause all the time. That is why most videos are uploaded heavily compressed.

But I simply can not live with anything less than the best possible image quality. Call it professional pride if you want. I much rather wait 5 hours for the upload than offering miserable quality.

It just seems to me this slingbow is only to be used by somebody that knows what they are doing. To have to align the arrow just right to pass through the second hole is kind of dangerous. I know you have to be WAY off to miss the second hole but ... i guess you have never met my friends. That arrow would be through thier hand in no time!

Good work as always. And I absolutely love the how-to videos. I assume that since you post how-tos you dont mind us reproducing? I want to make the metal W slingshot you posted a while ago.

I'm not interrested to draw arrows, but I think your intelligent design and concept is very well done.
The result is nice.
Congratulations.
Do you know how many joules it dévelloppe to explode the coconut , or approximately ?
