    Hello All,
    I don’t know if this is a technique issue or tool issue but I’ll start here. I have Miller Falls No. 8 plane which always leaves a scrape in the project. Because of this, I usually use my Stanley 5 1/2. However, I would really like to address this issue. Does anyone have suggestions on how I can fix this? I’ve attached an image of a 2×4 I’m trying to smooth (starting my workbench). The mark/scrape is usually just one side of the plane but that varies.
    Thank you,
    -dennis

    That picture looks much like plane tracks — as if you intended to remove material there, and the plane simply did its job. More material removed from one side might suggest your blade is protruding further on that side. If so, the blade edge on the side most easily seen in the picture is in really bad shape. or maybe you’re planing against the grain? — I can easily see jagged edges in the picture.

    But if you’re sure that’s not the case, how is the edge of the sole of your plane? Sometimes after flattening a plane, it’s easy to forget you’ve just made a very sharp edge, and that (as well as the front of the sole) can leave marks. In this case, again, jagged marks if you weren’t planing against the grain, so you’d know it with a touch of your fingertip.

    A bit of sandpaper should easily round over and / or smooth the edge if that’s the case, and a common technical error that I often make — while compensating for a blade that perhaps should have been sharpened some passes ago, one might also be planing with too much downforce, crushing the plane into the work, which can exacerbate the damage caused by an oversharp edge on the sole of the plane.

    Maybe it’s none of those things, but those are some pitfalls I’ve experienced.

    Are you sure it’s not plane tracks? A sharp corner of the plane iron protruding from the mouth can do that. See if you can feel the exposed corner with your finger. If it’s plane tracks, you can do a couple of things. You can gently round the corners of the iron or you can feather the edges while you’re sharpening. Put a little extra pressure on the right side, then the left side when you’re honing the iron.

    sometimes if a shaving gets caught in the mouth it can give you track marks where the shavings can dig into the wood, especially on softwoods, make sure the throat is always clean, usually it’s a sign you need to sharpen up, and it’s well worth rounding the edges of the blade, even on a jointer plane.
