Hahahaha man!
You remind me myself a few years ago,i wanted to cast some aluminum swage...
So i broke up some old gearbox to chips with my crushing hammer and filled up my biggest
casting spoon,it was about 8 pounds of raw material.
Point is,it WASN'T aluminum at all but magnesium.It took me about 2 hours and pile of sand to persuade it to stop burning.And IT burned like living xxxx, man.So don't do it or you gonna pay for red truck...
PS,i didn't neighbor wasn't keen to call them.
