Not too close yet Rob. I need proper tuyere attachment, patching lining (it's taken a beating with all the metal work and moving), make pouring shank, need to mix iron molding sand, make ingot molds, make blower /motor assembly, test fan output, make skimmer, line ladle, make more charcoal, break up and clean iron pieces, get weights for flasks, figure out a ladle heater. Seems like there's a never ending list ! And it will be raining through Wednesday. I'm going to guess a week 'til I get a nice hot ladle full of slag!! :lol: :lol: :lol: :lol: |

Decided as long as it was raining today I'd take an hour drive down to a town in Massachusetts that has a pottery supply business, and buy some silica sand. It's getting hard to find, and expensive for the real stuff because of health concerns. They had the pure stuff in #60 mesh. I had read a recommendation for #70 from Stewart Marshall, but 60 was all they had. So I bought 200 lbs of it and trucked it back. Brought plastic bins with me to keep it dry. I'm going to use Ironman's mix of 85% sand, 7.5% Bentonite, 3.5% coal dust (I might have found a source for some coal I can pulverize -- but can I substitute charcoal dust?), and 4% water. Ironman's video: (Ironman, if you read this, is this greensand composition by weight or volume. I'm assuming weight. Thanks!) |
