Here’s another video of my predator shoulder cannon mechanism.  I’ve now completed the mechanism for the bottom pivot which will raise the whole arm and gun up.  This is operated by a lever which will be mounted on my forearm.

This has really been scratch built from various bits I have lying about – the lever was made out of an angle poise lamp, the mechanism is bike brake cable fittings and a metal corner bracket that I bent into a flat shape.
