My problem here hasn't really anything to do with slingshots, but 'cause it isn't so different than a slingrifle trigger, i ask you for my problem. In a thick massive wooden shaft (spruce wood), I've got a lever tht should be turned 90°. I have to trigger that lever with my index finger at a pistol grip 10cm away from this. I hope this drawing can explain my problem better than my poor english description: Just now the shaft ist cutted up in two ways, one slot from the top to the bottom, one gap between this slot and the left site up to half of the height. I tought about using small strings, but the lever is relatively hard to pull and not so pretty stabile attached. and i need something that pulls the lever back if i take away my finger from the trigger. I'll be glad if anyone helps me. Greetings, Haecksler!
