I posted my forge setup and there was a couple people interested in the bellows I made. I use coke and coal in my forge and it works very well without having to resort to electricity for a fan. Here is the link to the file for instructions Blacksmith bellows. The main archive of cd3wd is intended for third world development but the info contained within the index is very useful for sustainable living or if you are interested in learning how to do things. The info on making a lost wax casting foundry and how to make your own wind turbine were very interesting.
