- action pic of sharpening
- closeup of a tooth that is really dull
- another closeup of the same tooth - nice and sharp!
I was limbing a tree the other day and things weren’t going as smoothly as I thought they should and there was a little smoke coming from the cut. I decided the blade might be dull, but I don’t really know what I’m doing. I was thinking about buying a replacement blade but found some info on sharpening in the manual and then I remembered the tool-care section of PEP and found this BB. So I bought a sharpening kit and read the instructions that came with the kit and the saw (over and over, trying to make sense of them) and coupled with some stuff said above in this thread, I performed a basic sharpening all around.
I have more to learn but this was a cool start toward competence.

Someone flagged this submission as an edge case BB. BBV price: 0 Note: It's hard to tell the difference between the dull and sharp pics. Could you try to get a better "sharp" pic for us? Or a worse "dull" one?
I have once again sharpened a chainsaw chain! Except this time, I really sharpened it. As a someone who's never done a lot of this stuff before, it's often difficult for me to tell if what I've done truly meets the standards set forth by a particular BB. But when I looked at the previous submission I made, it was clear to me that I didn't really sharpen the chain that much. I consider it a sign of progress that I was able to see that, because at the time I totally thought it was sharp. Hopefully this submission is up to snuff.

“There are no words to express the abyss between isolation and having one ally. It may be conceded to the mathematician that four is twice two. But two is not twice one; two is two thousand times one.”
― G. K. Chesterton
Tip: be careful not to heat up the tooth if using one of these electric sharpeners. No more than 3 seconds per tooth. If the chain is really dull, I go around the chain multiple times at 3 seconds per tooth to accomplish this. If you heat them up the steel will lose its temper and get soft.
It was really hard to get a close up of the tooth, so I included two shots from different angles.
Someone flagged this submission as not complete. BBV price: 1 Note: The hardest part of this BB is getting a clear close up picture of the sharpened edge. Check the first few posts to see examples.
I use a grid wheel model by Oregon. I do all my chains (usually around 10 or so) one direction and then adjust for the other direction. This way I can just put on a sharpened chain as needed. A few years ago I had about 25 chains made, saved lots of money. I also suggest using a depth gauge after sharpening.
