Author's Note: Thought I'd try making a SteamPunk style rifle from the bits of phone. The phone picture was the only source used. I used several pics for visual reference to get the correct types of proportions, mainly this one - Full view is recommended because of the width of the image.
Here's a WIP of sorts. It's really just me turning on all the pixel layers and adjustments layers in the PSD. It doesn't show the creation of each layer.
To quote Blackadder: "Congratulations on choosing the Armstrong Whitworth four pounder cannonette. Please read the instructions carefully and it should give you years of trouble free maiming."
