Glad you found that helpful. Iron is a different beast than aluminum at double the temp. of aluminum, 2600-2700* it is very unforgiving if you have a mishap, extra care is needed. My desire to melt iron was to see if my design could do it and for thrills more than need. My initial test was a 12 lb open face block seen in the last photo of the initial post. Many home melters of iron run into the problem of hard iron which is virtually unworkable, I added hardwood charcoal dust to the mix to try and maintain carbon content in addition to using soft iron scrap. To demonstrate that I produced workable Iron I sliced of one lip on my bandsaw without encountering any hard spots. Here's the picture:

I have just recently purchased a granite surface plate to check it against so I plan on making a small surface plate for model work out of the iron block. I am sure there will be times when aluminum just will not do and I will be casting more iron.
