Re: straightening pot metal?

Basically same method I did to flatten a curve that developed on my AC vent after it cooled. I also used a heavy flat bar to kind of control and spread the amount of bend so I could tell when it was straight and not going the other way. One thing the guy did not mention in the video is pot metal has a low melting point -- around 700 degrees is when it starts getting scary. When using the concentrated heat of a torch be extra careful not to linger in an area. The difference between softening and a complete melt happens faster than you can blink an eye. If you have an old scrap of something to practice on it might be worth getting a feel.
