What I want to know, is how did they keep the metal cool while they removed the ring.
In the early days when I work at MINSY, I was grinding metal with air driven grinder. We did QC grinding with an air driven 4" wheel and large weld with air driven 8" wheel. If you put some pressure on the grinder, the sparks will burn your cloths. The grinder will melt the metal at the point of contact. I had metal turn bright red, it was that hot. |
