Singing off tune…..Hi all you smart folks. I am finally using a Stanley #4 smoothing plane, sole and sides square and smooth, New blade, sharpened and slightly rounded edges. When I plane a walnut board, I get lines I can only see in reflective light, almost as if the fibers are compressed. Doesn’t seem to be the blade. Any thoughts?

If the lines are going in the same direction as you are planing they could be plane tracks, the corners of the iron digging in. This can be countered by cambering the iron slightly or feathering out the corners when sharpening. Bear in mind that even with rounded corners there is still a transition from straight iron to curved iron, and there is pretty much no way to avoid it entirely.
If they are going across the direction of planing it could be chatter, either because the cap iron and plane iron don’t have a good fit or because the wood isn’t held securely enough.

There are other reasons too, more info or pictures would help.

When I re-hone my blades on a 8000 waterstone, 6 strokes flat then 3 with light presure on each side! Makes more sense if you actually see it done?

There’s a possibility that it’s the corner of the plane leaving a track. I like to ease the edges of mine with a file so they have a slight chamfer with a smooth transition. A sharp corner will cut to some extent.

+1 If the sides/sole are dead square with sharp edge, you will leave tracks.
Break edge with file and radius slightly with some 100 grit paper.
Don’t want a sharp corner.

Hi All, back in with my walnut shelves and the number 4. I cleaned up the sole all around with a file and 400 sandpaper…All good now.
Thank you!

It pays to pay attention to the sole, especially if you’ve got any gluing going on nearby.

One time a tiny drop of epoxy glue got on the sole of my plane.

What a disaster that was…............
