Nachoman's 2010 spring bash chalenge

I did some more work to the frame, building up both ends, cleaning up flash, filling in holes, and installing couplers. There is still a lot of work to do on the frame, but things are definitely taking shape. I also carved off some details on the tank that I think were supposed to represent straps that hold the tank to the frame. I decided these looked bad, so I will make new ones out of brass strip.
