We had a pretty big gang of sand pounders last night, casting countless bits for the Omo and a few other sundry projects. There's just something so fun about the hot, bright, loud, scary, magic of molten metal and stone-age sand molds.
We are melting down old worn out oarlocks, which are made of a high strength yellow brass, which is about 58% copper and 39% zinc, with traces of iron, tin, aluminum and manganese. The zinc begins burning off at melting temperature, emitting a bizarre green flame.
I failed to get shots of the grinding and polishing crew at work. But the net result of the evening is that we sometimes get a little dirty.
