I finially found the time to make myself a forge and fired it up this past weekend. I must say I am pleased with how it turned out and I also found out that beating out rail road spikes is harder than I thought 
I used this as my inspiration

Anyways... on to the pictures:
First I made the adobe which is half sand and half cheap kitty litter with a handful of wood ash. I mixed water in until it was well mixed and similar to wet concrete.
I cut a hole in the side of the washtub for the air pipe, which is used oilfield pipe about 2.5 feet long with holes drilled about every inch or so. I also welded a plate on the end of the pipe rather than have it go all the way through the washtub. I know i'll just have to take off the blower to drain the ashes.
Once the pipe, washtub, and adobe were all in place it was a waiting game for the adobe to dry. it took a good 3 weeks in my garage but once it warmed up I sat it outside and it dried quicker.
The blower is a $11 hair dryer from Family Dollar.
It fired up nicely an heated evenly. I used charcoal I made from oak. I went through about 3/4 of a 5 gal bucket of charcoal in about an hour.
I look forward to getting it going again this weekend if the weather permits.
