Cast Iron Warpage

[waybackwhen]

What is the best way to even up a warped cast iron skillet?Seems to me there has to be a proven way by all the C/I folks out there.Is there a good Metallurgist that can help on this or a lay person?All info would be appreciated.Thanks

I've only heard of one person that was able to do it with any success.  He heated the piece red hot and used a series of presses and custom made pieces that kept the piece from being stressed too much and cracking.   I think he then let the pieces cool very slowly.   He only described the process, so I never saw the finished work and he's no longer on the forum here.   I've never heard of anyone else who was able to remove any warp from cast iron.

Well, I know for a fact that a 5 lb hammer WILL NOT WORK!  :-[

There is not a cost effective way that is 100% successful to remove warps.  Cast iron is too brittle and the one person that has done it spent a lot of effort and still had 'scaling' from the process.
