I'm working on my heavy frigate's weaponry (here...
http://www.hard-light.net/forums/index.php?topic=84699.0) and I just need to know whether a couple of things would be feasible or not, I don't need details for now.
1. Here's a sketch of the turret I want to build. Is it possible to tell the ring (blue) at the cannon base to perform a 180° rotation, to get the cannon to firing position and THEN tell the same base-ring to act as elevation mechanism? Maybe the sketch is more immediate then my explanation.
2. The main weapon of my ship (that huge cannon under the upper plates) will be protected by a diaphragm, an iris with 4 blades. Is possible to rotate the blades to open the "mouth" of the cannon just before a shot and then rotate them back to a closed position.
