Hi Strykernet.

I would first do a lot of concept sketches, and also I would switch software. I would choose Alias|wavefront Studio or designer for this since Maya is more of an animation and film software and Studio is aimed at CAD - and you need CAD like software for designs.

Designs usually should be modeled in NURBS Degree 5 - 7 surfaces and Studio excells in this area. Also Studio exports directly for production in various formats like IGES, STL, PRO/E etc.

anyway.

Create the concept sketches
model the object
export for production

ofcasue you can break down each point in smaller stages with rendering, texturing etc.. but that would basicly cover it..
