I was visiting with a friend about a pistol crossbow I built for an indoor shoot at a men's retreat this winter. He had an idea about a slingshot arrow launcher. So I started engineering in my mind and first thought was a plywood launcher but thought that a plywood one thin enough to attach the rubber tubes might not hold up to the stress of the heavy duty slingshot rubber tubes. I wanted a hole instead of a V-knotch to keep the arrow from dancing about when you draw hence the hole. I got to thinking that antler should hold up and so this is what I came up with.
It needs some better shelf to stablize the arrow at the rest. I was thinking on a Whisper Biscuit in the hole so if anyone has one they would like to donate to the cause please let me know.
