Hi all. This is my first time ever made slingshot. I know its not perfect, well maybe not even good compared to all what i can see on this forum but there it goes. I made it out of two pieces of 9mm plywood glued together since i cant find anywhere 18mm. Its not finished yet still need some final touch like place to attach rubbers etc. My question is how long should rubbers be ? i really have no idea. Already bought some theraband gold and waiting till it come so have a little time to ask some questions If u can give me any suggestions how to make batter ones i will appreciate. I dont have many tools yet. This one is made with 1 saw 1 file and a few sandpaper sheets.
