Had some time to kill today, waiting for my epoxy to harden.
So I made an entirely new slingshot, to be held like a bow, and with rubber instead of the bow string.
I tested it veeery carefully and with thick gloves. But no need!
It works very well. I need to make a slomo tomorrow because I don't understand why the rubber does NOT give me a nasty slap on my left hand.
Crazy! It even has serious power, in spite of the wide fork.

nice one mate,ide l;ike to see that using arrows!

Very nice.

Made one more cattie using this technique. Needs some more polishing, but shoots very good.

JoergS,
It probably has good power because of the wide fork - rubber has a weird way of storing energy and one of the most critical components of a catapult shot is time to accelerate the bullet. A catapult with narrower forks but the same length bands will have more slack in the bands when they're at rest, and bands which are slack aren't accelerating anything.
So while you might have reduced the overall draw of those bands by using a wide frame, you will have increased the effective draw by removing a lot of the slack from the system.

makes sense.
jorg using the priciple ov the 'V' applied in this context it would be very good!
JoergS
Well, some slack is needed, otherwise it would be a pain in the backside to load a bullet into the pouch.
The new model is 30 cm long, so the bands have to be 15 cm each minimum, otherwise the pouch would be stretched and cumbersome to load.
A draw length extension like I use it in the "V" should only add about 5 cm for each band, otherwise the bands would simply be so long that only an octopus could draw it out in full.
In a way, the wide fork is a draw length extension in itself.
Greetings from Germany, where the fall is kicking in fast
