Chain won't sharpen....

[jakethesnake]

That's actually my favorite chain. I've had some minor issues with it. Hardened depth guages. But I've had issues with every brand I've ever used.

I've overheated cutters with the grinder. Makes them a bear to sharpen with a file

It does sound like case hardened cutters due to overly aggressive grinding. But t4driller said he saw no overheating discoloration. hmmm.

Some more pics trying to show the color of it. There's no signs of being heated up that I can see. The only thing that stands out to me is under the top plate I can see a line. I'm assuming it's the plating and it looks alot thicker then the other chains I have.

The first thing to do is to touch up one of the cutters with the grinder and then see if it is easier to file.

I remember I had a Stihl chain that was just like you are describing....the only thing I did, was grab an older file, and "hog" some material out....it seemed like you are saying, there was just a really hard part in some of the cutters, it was very strange....I didn't have a grinder at the time, so I had to make do....


I will say like you I found it very strange!!!!

I have not had that problem agian...

Add me to the list as I had one several years ago that I couldn't sharpen either on a customer machine. Just ended up installing a new chain. The chain was pretty messed up anyway and time was pressing on the repair.

Any luck?

Any luck?

Haven't had a chance to mess with it anymore.

These work great for breaking through.
Also the best I have found other than solid carbide to work a cutter back on some of the trashed chains brought to me to sharpen.

All of them are the same. I tried atleast 6 cutters on the one side. I did not try sharpening the other side.

That could be a good thing. Hold a edge better once you do get an edge. I like carlton and stihl chains on my saws

I forgot all about this chain.. It's hanging on a nail somewhere. When3vwr I bought that dealer out I got a bunch of chains that homelite saws. Was a couple old stihl chains in there is like to use, but the dl count is a lil short for the stihl bars I have. Need to take some apart and make them longer/shorter. The ones I've used seemed to be better then the new stihl chain.

The chrome layer is very thin. While it is possible that the cutter was hardened in the manufacturing process (typically not heat treated properly) it appears to have been sharpened by someone, so I am going with the 'overheated by a previous sharpening event with a grinder' camp, even though you don't see any discoloration.

Typically, as noted, if you grind through that section, it can usually be filed afterwards. Worst case, it may be a grind-only chain that still cuts fine.

You're going way too deep for one thing .If you're going to use a guide I think either old style Oregon the one Stihl sells are the best .Pferd files seem to work better on hard chain such as Stihl brand chain .Stihl chain will knock the teeth right off an Oregon file and most likely this chain will too .Fact I think the "house brand" Baileys sells,woodland pro is a better file than Oregon .

 

[jakethesnake]

Woodland pro files are pretty good. I buy the 12 packs of them.

I typically go deep on my grind so I don't have to work bout the gullet later. But everyone has there own way to sharp a chain and my chains work great on my echo top handle hard or soft wood.
