Terry, I just found this post and did not realize it was finished.

To shrink metal, all that needs to happen is get the metal hot enough that steam rises when water is applied. The amount and area size you need to draw it will determine whether you choose to use a water-saturated rag, or an air hose blowing air over the surface, ...or just allow it to normalize back to room temps on its own. If the metal has been turned red, that is too high of temps. This, like any craft, takes some time to learn how to properly execute the process but this method of repair is much more stable and lasting.
