Okay perhaps a little out-of-the-box, but anyone ever considered doing a small-scale Bessemer conversion? Could be a fun way to turn 'unuseable' cast iron into true mild steel. I'm thinking clay crucible (cheap, easy to make) in the acid Bessemer method, with a modified air source from above, like the basic oxygen process; this makes construction easy.
Thoughts, ladies and gents? Issues? How does one identify low P cast iron? Am I mad for thinking this? Are you mad enough to try it?
