At the suggestion of Elkaddalek [link]
I am building a paintball gun for my dalek model. This is a work in progress; I have yet to add the paintball hopper, air supply hose and detailing.
Updated on 17/09/2011 to change muzzle brake, add detailing to mechanism under barrel, and to start on hopper attachment.
Updated on 18/09/2011 to continue work on hopper attachment, and to add a frame around the barrel (a targeting sensor perhaps?) to make it look more dalek-y.
Updated on 20/09/2011 to revise the frame around the barrel and start work on the air hose.
Updated on 22/09/2011 to remove frame around barrel (it's just not right yet), improve the air hose (although there is still a bug in the way it coils), and to experiment with textures.
Updated again on 22/09/2011 to fix the bug in the air hose.
24/09/2011 - Further progress will be shown in a new WIP [link]
