Busy Busy Workers

Ok I've pretty much finished the worker arms, they could do with a bit of optimization and improvements in places, such as the turner wheel at the back, there isn't enough sides so it looks really jagged rather than smooth.

At the moment, these arms are coming in at 5.1k polys, a lot more then I really want. If I can bring them down to 4k I'll be happy, 3k and I'll be chuffed to say the least. Saying that though, these will be split into 2 or 3 so I can have them damaged or broken, so it shouldn't be too bad, especially if I can occlude some.
