Overheated bar

[Mill_wannabe]

I picked up an 028AVEQS yesterday, and the bar has significant blueing all around. I presume it was run without oil at one time, but I did see some threads saying some Stihl bars are laser welded and blue under the paint. Would you say this one is toast?

I need to figure out the picture posting. Maybe this will work in the mean time?

The bluing is usually from the hardening process given to the bar edge and is typical on heat treated bars before painting. Your photo did not work. Here's a photo from an old bar that I have with the paint worn off.

Thanks, RacerX. I think I fixed the picture. Is my bar OK?

True up the rails and check the groove width. Should be fine.

Also looks like bar never got flipped, run it "upside down"/flip it after several chain sharpenings.

I agree with the Mad Professor, clean up the edges, flip it over and it should be fine.

It's supposed to look like that.

Agree with everyone else. Dress the rails and it'll be snazzy.

Had a bar that looked like that. Blued top and bottom, but not around the radius of the sprocket.
Some hinted that it was burned. But I always kept the bar oil topped off and had thought myself that it was just heat treating.

Do maintence on the bar, wash it, sand it clean, paint it white and stencil Stihl on it. Just like new again. Seeing the bluing I don’t like. Lol
