I talked to Tobias, fellow slingshooter and the current record holder for the most powerful handheld discipline, about further enhancing the available designs for hammer grip shooters.
We both use my "Hand Howitzer", which is a great slingshot. However, the "Lead Launcher" is also a good concept. And two of my other frames have advantages, too. So we spent some time thinking about how we can "marry" all these designs.
Here is my take!
The fork is low, which is achieved by making the "throat" very thin - but deep. This way, it is totally solid and won't ever break under stress. It thickens out to a 20 mm round tip, for easy band attachment. The handle is very narrow right under the fork, which is great for holding the frame in the webbing of the hand. A huge palmswell gives you fantastic purchase, and the curved front of the handle is from the "lead launcher" design - very effective.
I started out with three identical forks, cut from 18mm Multiplex.
Rasp work done.
File work done.
Totally flat over the hand.
Banded up with three layers of TB Gold, very powerful - but manageable with this great frame.
Here you see it next to the three other models that influenced it.
Hope you like it!
