Topic tags/keywords: question maple

I brought home some rough cut soft maple and when I was planing it down, I found some stains that went the entire length of one side.

After I ripped a clean edge, it looked like some of the satins go a good 1/32” deeper. They aren’t a problem because those surfaces are not going to be exposed.

Just curious to the possible cause.

The other side was fine.

Looks like sticker stain to me. It should mill right off.

For the streaks, okay. What about the dots? They are only an inch or so apart?

They look like large planer feed roller marks to me. Lumber mill planers have steel teeth on their feed rollers.
