The first one is the forge that I use when doing living history demos at Lincoln Log Cabin Historic Site (Abe's Father's last home site), Lerna, ILL. It is built on the order of an old artillary cart forge, with a 4 foot long 2 stage bellows. It's a lot of fun to work with.

The second is my shop forge, at home. Nothin' fancy, but it works for me. The hood is just barely visible at the top of the picture.. It goes out a 12in X12in roof vent.
