i like the High Hammer very much! for targetbands is this a very nice and comfortable slingshot! with much space between your hand and the ammo. good work!
the X-Hammer reminds me on a idea that one friend of mine had some time ago, but he dont made it real, now i looking forward how the X-hammer work for you! what do you hope from this design ? more power or more accuracy? or just a fancy design ?
The high hammer will work well, the X-Shooter... I don't know.
I tested a ring-like design a while ago, and it was a fail. I use pretty strong bands, which means I always flip my wrist down. This happened with that frame, too, and I hit the top of the ring a few times - until it broke.
I think you have to use very weak bands so you can hold the frame very steady, or you will have to attach a wrist brace.
Thanks for the feedback, Joerg. I was going to cut 1/2" straight TBG bands for the X-Shot and set it up to draw forward and then back through the ring. It is more of a design exercise than a serious attempt at a usable slingshot.
