    Default Hand Filing - Free-hand

    this is sort of a spin-off from a conversation in another thread of mine.

    Trying to learn to hand-file (round) "free hand".

    Below are photos of my "chips" from my latest attempt at hand-filing my ms461 w/25" bar

    It isn't 100% "sawdust" ... and there are some *bigger* chips, but not the way it is supposed to look.

    Note the wide variation in chip sizes...is this a clear indication that some teeth are sharper than others?

    .... or does it have anything to do with teeth being all different sizes (Buckin Billy said same tooth size didn't matter at all).

    The depth gauges/rakers should definitely be low enough.
    -- I used the single tooth Husqvarna type filing gauge followed by the Oregon "saddle" type (spans 2 teeth with depth gauge sticking through slot in center) just to make sure.

    Do these chips give you enough information to diagnose any specific errors I'm making in my filing?

    thanks for looking and commenting.

    From what I can see of the chain, that's about what mine looks like when I've hit dirt or something and stop to sharpen it. Looks like you need about 3-4 more good strokes on each tooth.

    I showed my ground-man the 4x's zoom. He was astonished.

    I can spot a not sharp chain from far away. I think in part because I had really good eyesight and bright Nevada sun to learn by.


    From the blurry picture, I'd guess every front-working corner is bent down.

    Round-top, aka chipper chain, aka micro-chisel is way more forgiving.




    Side plate pictures?



    13/64" or 3/16" round file?
    Raker/ depth gauge offset spec?


    Make sure you are using sharp files!
    If it looks like I asked a question, but put a period, it's probably a question.

    I'll also offer one more small tidbit told to me by an old timer 30+ years ago-
    When you stroke the chain tooth with the file, use long straight strokes. Like you're beating off, consistency gets the job done. You don't play it like a fiddle.

    I've seen some guys file and it's amazing the saw can even cut when they are done. Hands and file flailing all around like he's conducting an orchestra or something. Focus on consistent repetition in the exact same plane on each and every tooth.

    Can you get some close up pics of the cutters?

    I'm glad you ended that sentence with cutters after Skwerl's post.

    I do find there can be a difference between wood chip quality depending on the kind of wood you cut. Some may naturally end up powdery or inconsistent, but in general will be rectangular. I remember worrying about how I wasn't ever getting my chain sharp enough as a beginner when chainsaw manuals stated and showed that a sharp chain will produce short noodles, and I'd never get noodles, just rectangle chips. Only a few woods will produce good cross cut noodle chips.

    Looks like oak in your pic? Oak splits easy, the chips could be getting split up on the way out of the cut. Chip thickness looks good, but as the chips get thinner from the depth gauges not being low enough, you will get more powdery chips. I think different sizes of teeth will cut at different depths relative to each other even if a depth gauge guide sets the cut depth equal on each tooth. You can get away just fine with uneven teeth, but it can eventually give you problems.
