So I decided to take on this huge gun. It's Optimus Primes gun based on the Animated film. What Im planning to do is work with the cartoon shape and then modernize it and detail it with all the heat sinks pipes and whatever else to make it look more realistic. The original gun would be too smooth and boring. The great thing about this build is I can work on each section individually, every piece slides off the main tube like a giant shishkabob. Im actually aiming to finish by the summer because I have a wicked opportunity to get it on display at TFCON12 in one of the major booths. Heres a first kinda look. I'll keep posting as things go. Cell phone pic, not much more to see yet lol
Here's the reference pic off the web I based on for dimensions etc.
