Some days ago, John from Texas (close to Austin) sent me four great, fat forks from Persimmon. The tree was felled by a storm, and supplied plenty of very nice wood.
Persimmon is an interesting wood, it is a kind a ebony. Subtly brown, great grain, and very dense.
As always I will send John one completed slingshot back in return, and have made the first one the last few days.
A Hammer-Howitzer, what else, it is the best design I found (so far). A great cooperation between me and Tobias brought out this shape, which I think is hard to beat.
The wood was fresh and is known to crack easily, it took many careful microwave sessions to dry it.
It may seem a waste to start from such a thick fork, but the HammerHowitzer shape requires a very thick and wide piece. The raw "board" has to be thicker than 2 full inches, otherwise the handle won't reach this sweet depth which makes the frame so controllable.
Sanded, wetted, resanded, oiled (linseed), and polished.
