pic: Simple hook delivery system

[IamBuild]

I strongly think climb is within reach for just about everyone (To the point where I'm thinking about designing a "Climb in a box" cheesecake).With only 3.3 ounces I made a launch tube, hook, and rope that has a 95% success rate. It's shot with pneumatics and if you include the motor, winching system, and the solenoid, the whole system can weigh under 3 pounds. If you have any questions about this feel free to ask and I have some pictures of it here: https://docs.google.com/presentation...it?usp=sharing
