Compound sling revision 3. This version has the pouch designed by NooneOfConsequence incorporated. You can see an image of his pouch earlier in this topic.
I made one small change. To the retention cord that wraps around the projectile while it's in the pouch, I added a small leather tab. The intention is to create more surface area for the cord when it's pushing the ball out of the pouch. Here are some images with an orange ball held in the pouch as a projectile:
And here is the full sling:
The primary retention cord is paracord. The secondary retention cord is braided linen. And the release cord is also braided linen. The booster-weight is the same thing I used in my previous versions of this sling, it's a plastic ball filled with silicone. It weighs approximately 130 g.
Now on to the most important thing, how well does it work? I'm not yet certain, but I think shows promise. I've only done 6 or 7 throws, which I tried to record, but it's so hot and humid that my phone just quit recording. I also had the angle wrong, so I wasn't even in the frame for most of the video. Needless to say I just deleted it and will record another.
I was planning to do another recording right away, but a little rain came through and bumped the humidity up from 100% to what feels like 120%, so I'm not doing it today. But a video of this thing in action will be coming soon.
The only real feedback I have at this point is that the pouch may not be releasing the ball as cleanly as I would like. But if that turns out to be the case, I have a few ideas that may help.
