To get certified for this BB, post three pics:
- action pic of sharpening
- closeup of a tooth that is really dull
- another closeup of the same tooth - nice and sharp!
This is my attempt with pictures and explanation:
1) This picture shows a lot actually. The first pointer is that when I sharpen my saw, I get comfortable. This is not to be hurried, though it only takes about 5 minutes to file a chainsaw. I do it at my kitchen table, using a towel under my saw to catch filings because I am married do not want to experience divorce again. I am warm, comfortable and dry here though, so I do a good job. You will also see in the photo I am only using a bare minimum of tooling, nothing expensive: a chainsaw and raker file!
2) In this photo you see the dull cutter. Here I have to make a confession, it does not look super dull because it is not. I never let my saw get dull, and no one else should either. When you do, the teeth get hot, then the bar, then that heat gets transferred to the bottom case of the saw where the crankshaft is. Being only 2 strokes, they get very little oil. I have gotten 22 years of heavy life out of my saws because I always run them sharp...no heat build up, so no engine problems! Still this tooth is dull, you can see some dulling at the very top of the cutter. But also look at the raker. This tooth is half filed down, and yet the raker is still pretty high.
3) This is just an action shot as required. Ever since 1990 when they started adding the engraved angle line to each cutter tooth, there is no guess work when it comes to filing a saw. I used 3 strokes of the file for the cutter, and 2 for the raker. As for the Stihl hat I am wearing being just plain wrong...filing a Husky with a Stihl hat? Hardly; this model saw is JUNK. It is not that big of a saw granted, but it has no power and is a rattle box. I do not recommend this chainaw to anyone!
4) This shows the finished filed tooth and raker. Its cleaned up and ready to cut. The raker has been filed down just a bit to allow it to take a nice slice of wood.
A sincere thank you to all of Permies Forums for making Christmas special to Katie and I, and our four daughters. Thank you!
