I finished the bola launcher yesterday. It was a ton of work. Two full blown "slotted barrel" type sling-x-bows, with two individual triggers, plus the central trigger and the fan-out mechanism. You can adjust the angle between the barrels, as I have no idea how much of an angle is needed. It was dark yesterday when I called it a day, so I don't know how well this works. Today, another film team will show up, and tomorrow a news magazine will visit. Had an 11 minute piece on German nationwide TV yesterday. I am really busy and seriously think about getting an agent. I also had to make the bola. Two pieces of 20mm rectangular steel, connected with a length of paracord. Each steel weight is 87 gramms = 3 oz.
