Concepts - Gun Mechanics Test

Here is a quick 2D animation of the gun mechanics from the side:

Here is a test I made in maya:

For the rigging I will be using the connection editor to connect the rotates of each cog. I will need to use multiply and divide nodes in between the connections as the speeds of the cogs will be different. The beginning cog will be the largest, at the elbow and this will be the driver for the whole sequence therefore there will be a nurbs curve controller; orient constrained to this cog so that you can cleanly control the mechanics. The node connections will finish at the gun pole and the actual gun itself will have individual controls giving the freedom to animate all the gun parts however you want.
