Straighten a chainsaw bar

[Keta]

It will not be easy without a press, I love mine.   First determin where the bend is and how much by running a string or wire from the tip to the base and marking it.  Then clamp the bar full width a inch or so from the bend and pull the end, a large crescent wrench would help.  Check the bar and repete until the bar is streight.

Heat will alter the temper of the metal. 

Absolutely, if you apply too much. That's why I suggested a heat gun. You have to be very careful with a torch not to get it too hot.. One has to be careful applying heat to tempered steel but a little heat helps to get some movement.

 Getting the bar straight again is just the first step.

The groove that the chain rides in will also be deformed.

I bent mine one time. The Proctologist got it straightened..!
