All good homemade slingshots will require these materials: good y-forked frame. When 20 years ago I were a kid , the only source of y-forked stick was from chopping a tree's branch. Went the forest and hunted for a good y-fork and chopped it off. Then is to check for cracks, imperfections, and rotting in wood as one wouldn't want slingshot to get snapped when they are shooting it.
But nowadays, with many advnaced tools bought from Internet, I am not limited to the y-forked stick, I can make a forks from timber. Of course, for safety reason, not any wooden timber, only make homemade slingshot with some high quality timber.
Anther thing one requires is elastic band. It is a string that you I'll be pulling back as well as snapping for slinging ammo of yours forward. The stationery band or surgery tube works, but if you are serious to make a slingshot, I recommend you buy commercial slingshot bands which is cheap and offer at least triple power compared to other alternative bands. Such as DANKUNG SHESHOU band.
