Shaper table extension

That actually worked on a piece of chilled cast iron I had a few years ago. I was a little surprised at the time, since I wasn't sure cast would respond to it, but naturally glad that treatment worked so well.

Whatever that mystery metal is, if it is treatable that way, the main thing is to let it cool slowly -- I buried mine in a bucket of woodstove ashes after it was red hot.
