I Hate Porting Heads!!

I used to grind cast iron when I worked at an automotive stamping die plant. A tracing/milling machine would rough out the shape of the fender, hood, whatever, from a model, then we would grind, grind, grind and, oh yeah, grind some more, for weeks. That work is done by cnc now. I would clean up and shower, by the time I got home from work, my hands were dirty again. It came out of your pores. It was in my ears, nose, everywhere. You couldn't keep it out. Really fun in the summer. Now, I rust like the tin man when I'm out in the rain! I don't miss that one bit!!!
