When to replace a bar

[Haywire Haywood]

I'm going through a 290 that a buddy loaned out and the fellow scorched the bar pretty badly. Color changes 1/4" back from bar edge. It dressed up fine, but I can get .075 worth of feeler gauge in the .063 bar. Time to chuck it?

na.. if the saw cuts straight just use it forever. Squeeze the rails if you're worried (I wouldn't bother).

Sure the discoloring isn't from where the bar edge was hardened?

Is it the metal or the paint?

Get a new bar, and use the old one to make a machete... Bars make excellent machete's.

Just so you know.. under the paint the rails are "blue" from the laser heat treatment, which goes to Gary's point...

There's no paint left on the bar edge... it may very well be from factory hardening.

thanks,

All my ES bars that finally wear the paint off on the rails (which takes some cuttin'...) have the blued "hardened" edge...

a picture's worth a thousand words....

That's the factory hardened edge... dress it up and keep usin' it.

Maybe some paint too...

Good deal. I learn something every day. He said that his buddy had the smoke rolling off it. I assumed it was toast.

OK there Gas-O-Gary, you've brought up a way to keep this thread going. What about painting? Any tips from the gang? Sand off all the old paint or do you just prime and paint? What paint do you use that will last? Do you bake the fresh coat?

 

[Lakeside53]

If it's bad, take off all the paint, buff and wax...

I would call this a problem

Here's the tip on my 360pro after the last outing. I'm gonna call this a problem.

Is that why you are supposed to grease the tips??

No, that is why you dont pinch the tip. onve you heat the sprocket up like that its gonna fall apart..

Well, I would have to drill a hole in that Pro bar to do that. Good bars do not require you grease the tips. As far as pinching it,,,,,,maybe,,,,,but it's just worn out fella's the sprocket in the end has razer sharp points and shows alot of wear. I figured if the sprocket is worn that much the bearing isn't far behind, causing the added heat. I've been looking for a replacemnet tip, found one on fleabay, but the seller says"Although it fits the sthil bar's you have to add some to the chain" his is longer than the factory. Crap in other words. Guess I'm either gonna have to break down and buy the stihl one or get another bar,,,,,Damit.
