3D Modelling - Gatling Turret

Hi all.
It's been a while since I last posted so heres an update on what I've been doing:

I have been getting stuck into modelling all the things I need for my 3D short film (storyboard available for download in previous post). This is a gatling turret that will feature in the animation.

I have only been using 3DS Max (program to be used for all the 3D work) for about a month now. I'm learning fast and hope to have all my modelling done by the end of this term.
