Since it is not that much off being straight, I'm hoping that will resolve the issue. I don't think that will over-stress the metal but anyone with experience has a few more days to chime in before I go through gaining experience, which sometimes means learning what not to do ever again.

- Ooops- I didn't realize the shaft, blade and the guide pin were of a piece (AISI 1018?)- yup, moderate heat and copper vise jaws- just don't use the old machine shop Rule of Thumb- "Never force anything, just go to the tool crib and get a larger hammer"-- That's in jest of course- let us know how it works out please, Jack
