Here is my latest work; a viking age forge for a viking-group in Norway.
There is not much archaeological material to define the viking age forge, but a few forge soapstones and a wood carved relief on a portal to a norwegian stave church. It seems fair to say, that there was no double chamber bellows used, since we have no findings, but only two bellows used. The portal from Hylestad Stave church and a large carved stone at Ramsund (Sodermanland in Sweden) shows us the use of two bellows put together (pictured below).
Below is a foto of the remains of two bag bellows and the mouthpiece from Nydam mose an ironage sacrificial burial bog in Denmark. The bag bellows has worked as one, blowing air through the mouthpiece.
My interpretation of a viking age forge and the result is pictured below. The soapstone is from Norway and has a natural finish. I have used oak, ash, willow and juniper wood in the construction of the bellows and the table. Of Course I try only to use materials and techniques from viking age, but here the bricks hide a metal plate, and the bricks will be covered with clay, sand and organic materials, so the forge will last longer. Yes I do also use a few screws where it’s not visible 😉
Her is a couple of picture from the making of the bellows:
