Sharpened chain run amuck!

[billyboy]

Picked up a saw at an auction I intended to resell. 16", 3/8, full chisel that had been rocked pretty bad on one side. Usually sharpen mine with a dremel but this one was too far gone for me. I didn't have time to take it to my usual guy for chains that need serious correction, one hour round trip. Took it to local hardware store that had off site service. It came back a mess. The rocked side wasn't touched much and the good side didn't even cut a new edge on the top plate. The gullet was mined down into hell. Looks like the village idiot was given a grinding stone of some kind.

Wow! If someone feels they can legitimately charge for that I'd be pretty sceptical about buying anything off them.
Be interesting to hear what their response is if you take it back (which I definitely think you should)

I probably should have chucked it in the recycle bin. Another brain fart on my part.

Not sure about paying someone else to sharpen it, but I definitely would've salvaged it... once fixed I'd say you'll get another dozen or so sharpens out of it if you keep it off the ground. Bring the top plate filing angle back to 25° & bring the cutting angle back to the ~55° it should be & you'll get a bit more out of it again.
Given the appearance of the rakers I'm guessing that they weren't even deliberately filed, just got tagged by the underside of the disk as a result of how steeply set it was

I took it back to my shop guy who I take chains to and he did a pretty good job of salvaging it. It cuts pretty good and straight. It isn't perfect but it'll do. There's still some life left in it.

This chisel's corner is bad all of the way back, I would toss it.

This is one reason I don't use full chisel. A semi chisel would have been a bit easier to rectify and might not have been screwed up as much. I cut mulberry out of fence rows and ditches that the snowplows throw rock into. i use junk chain for that and they are small trees. I'm just a wood burner, too old to get in a big hurry.

You make a great point but I would probably save it but it would be a lot of work. I would never sharpen it for pay though and that is what the O.P. is talking about here. Bearing in mind of course that this may or may not be the worst tooth on the chain.

Toss it , even if you sharpened it back to that line it's not going to cut good. I'm not buying any more full chisel. Steve

Looks like it should go back farther than that. that corner edge is baaaaddddd.

The other parts of the chain look to be in good shape and Stihl is one of the better chains.

Hopefully a lot of that is rock shine but some of that corner is definitely abraded away.

Like us, it will never be new again.

I cut up a green mulberry , about 20" diameter at 4' height, 47cc 028, marched right through it and it cut straight. Made chips and probably some dust. One side of the chain was in good condition. Too bad I took it to the wrong guy the first time.

Hunter Biden must be sharpening chains now. That definitely belongs on the wall.

 

[Rooshooter]

Whoever attempted to sharpen the chain should never be allowed near a grinder again, for a start it really is non recoverable and should have been rejected before attempting to sharpen it.
If a customer bought me in a chain like that for sharpening I would tell them to bin it.

 

[pioneerguy600]

Someone took a , mini side grinder to that chain, the grinder disc must have been close to 5/16" thick.

Here are a few pics. As I said one side was in decent shape. It looks like the side that was rocked, he changed the grinder angle a bit to take more of the tip off. It does cut pretty well I must say. It marched right through that green mulberry.

@pioneerguy600,, I don't know what was used on that chain but i have never seen such a pigs breakfast in my life like that.
