When a plane leaves a rough patch, taking a deeper cut is rarely a helpful first response. Pause and look at the wood, the edge and the direction of travel. A small test pass can tell you more than another full-length stroke.
Look along the edge as well as the face
Grain lines on the face are useful clues, but the edge often makes the slope of the fibres easier to see. Try a light cut in the direction that supports the fibres instead of lifting them ahead of the blade. Mark a small arrow on a hidden area once you establish the easier direction.
Do not expect one arrow to solve every board. Grain can reverse, especially around figure and knots. A direction that works well at one end may produce tear-out farther along.
Reduce the variables
Secure the board on a sound bench using a suitable stop or holding arrangement. Start with a sharp iron and a fine shaving. Lee Valley's plane guidance explains tear-out as fibres lifting before they are severed; blade sharpness, cut depth and mouth opening all affect the result.
Make a short trial in a place where a small defect can still be removed. Inspect the surface in raking light. If the cut is rough, try the opposite direction with the same light setting so the comparison means something.
Know when to change the approach
A narrow mouth and a light cut can help, but difficult grain may call for a different effective cutting angle or another finishing tool. Plane designs differ, so follow the setup guidance for your tool rather than transferring an angle from an unrelated model.
A well-prepared scraper or a careful sanding sequence may be the more practical choice for a local patch of reversing grain. There is no prize for removing extra thickness while insisting that one tool do every part of the job.
Before final surfacing, check the board's remaining thickness and the dimensions required by the project. If a small tear-out has already appeared, decide whether it must be removed completely or can face the hidden side. Make that decision deliberately, before another pass commits you to a thinner part.
