Just thought I would stir the pot.
Anvil:
The image below is a 20 lb sledge with the head set in a stump; I would advise boring a hole in a better specimen such as elm or hack berry, but this should give you some idea. Just make sure that the force from your hammer travels through to the ground.

Forge:
Pictured below is the first forge that I constructed.
2" pipe from the local hardware; nipples/2 Each, Flange/1 Each, T/1 Each, Cap, 1 Each, Brake Rotor or Drum/1 Each, and 3' of Pipe.
Weld or bolt flange to Brake Rotor and screw assembly together.
You must use the T with the nipple and cap instead of a 90; the T will prevent obstructions in the air stream and the cap allows for cleaning.
This forge can be connected to a vehicle exhaust with a length of flexible pipe sold at your local auto parts store or some sort of blower such as a hair dryer would suffice.

The above items are cheap, readily available, serve multiple purposes, and are easy to store and transport.
Hope this helps.
I will post photos of some tongs tomorrow.
