Venturing into another new area for me... ![Blush Blush](http://www.metalworkingfun.com/images/smilies/blush.gif)
I have an iron casting here (camel back straight edge) that I want to attempt to turn into a usable tool.![Angel Angel](http://www.metalworkingfun.com/images/smilies/angel.gif)
The raw casting has been fully annealed so that it will be machinable. After it is rough machined how does one determine if the casting needs to be thermally stress relieved? Or is that a given?![17428 17428](http://www.metalworkingfun.com/images/smilies/17428.gif)
I would hate to spend months hand scraping this thing only to have it twist into a pretzel later. Anyone been there / done that?
