8mm steel bar, and some wood from the armrest of an old chair.
After making it, I realised the fork was quite high, i might bend it outward to make it wider and lower, but i'll test first like this
You're probably right, but I don't have equipment for advanced woodworking, most of my slingshots are made with handtools.Just a suggestion:
Try a fatter piece of wood, where you can cut grooves that the wire frame will slide into.
It would give a much more stable handle.
I dont think the height of your slingshot is an issue, using a pistol grip handle.
