We all know the hazards of DIY. Anyone who’s ever done any sanding knows that a lot of that stuff ends up in your nose. It collects. It really bulks up those bogeys.
But machining metals is another ball game. Metal shards up the nose is one thing for a start.
But in machine shops, you’d be told not to allow the chaff to build up anywhere. You’d be told to keep the floor, work surfaces and machines free of build-ups. This is important when dealing with aluminium and steel. But there’s something they never tell you:
Iron Oxide + Aluminium + Bogeys —–> Thermite bogeys
You have been warned.
