This Is Why I Sharpen My Own Chains!

Compare these to teeth. Bottom one is decent but not great. Note the bottom tooth was sharpened by a round file and has had the gullet filed out.

What makes you think that bore cutting will be more problematic with that chain? To my eye it doesn't look sharp at all. In fact to my eyes it looks like a complete hack job.

Because I have actually used it and can attest to its feistyness attempting to bore cut dead seasoned oak. It chattered like crazy and wanted to rip the saw out of my hands.

This looks a whole lot better than mine. The side plate angle is much more vertical.

My chain cuts well but I do want to start square filing it.

The side plate angle that your cutters are ground at don’t look excessively sharp, which would make it more aggressive yet. Are the depth gauges too low?

The depth gauges were also ground but are about right according to my progressive gauge.

Hello,

I received two chains like this when a volunteer sawyer retired and turned his saw back in. Anybody see anything wrong here?

Looks like his wheel is almost perfect square. Looks like rakers need a little touch but hard to tell from pictures. Might cut ok anyway.

Ok a look at the second picture shows hand filing way down in the gullet lil th file was too small and didn’t hit the cutting edge at all.

You want insight into how badly I expect everything to go... before I opened the images, I expected to see that he'd sharpened the drive links or something.

I think it’s so blunt it can’t sever. I’d give a few swipes up under the top plate with a 5/32”

I agree. Would cut terrible.

I'd say the chain on the right was hand filed to me, that grinder head would have to be tilted pretty hard to get that hook on left. Agree the riders are pretty low, too much hook. The right chain looks like it could have used a new drive sprocket and some bar maintenance too!

The photos are opposite sides of the same chain. They were definitely put on a grinder. Good point on this possibly screwing up the drive links. I didn't look closely at them.
