Anvil - I'm not overly fond of the shape, I will most likely rework this.

Quenching Barrel - I had the devil's own time learning to shape the staves so they would form a proper fit. A lesson about curve modifiers and object arrays I will never forget :-)

Okay so here is the hearth and bellows setup. Working on the anvil and various hand tools (hammer, tongs, quenching barrel, etc.) next.

@Quenten Thank you sir. I got a start on the bellows. The base of it anyway. I still need to make the support frame, the handle, the tube support, etc.

So, after spending most of the day learning how to add both smoke and flames in blender, I can tell you that unless you intend to produce an animated product, the process isn't worth the effort. At least not with my limited knowledge. Granted, it can produce some astounding fluid effects but it takes some effort to squeeze them out. And you can't truly appreciate them unless they are animated.
