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!
