With the recent thread on building a forge, maybe there are a few tips out
there on the fabrication and placement of the forge hood. Mine is a simple
side draft that is made from a 2x2x2 steel box with one side cut out and a
4" duct chimney. seems to work pretty good once the air inside the box heats up.

         The hood at our groups forge was rebuilt last month. A standard
hang over the fire, inverted pyramid type with a 12" pipe. Before the
rebuild it smoked a lot and it seemed to put more heat on the smith than it
did on the steel. By lovering the hood about 6" made all the difference in
the world, much less smoke and slightly less heat than the surface of the sun ;)

        Any other hood tips?

A side draft forge hood needs a smoke shelf to function at its best. About four 
inches deep on the side of the box away from the fire, six or so inches above the 
top of the opening, where the box starts to taper to the chimney.
See articles in The Anvil's Ring, March 79 and in The Blacksmith's Journal, 
September 92.
Also, a bigger chimney: these articles recommend 10x10 and 12x12.
