Wood Plane Mouth Fix
When making a Krenov-style wood plane, it’s easy in the beginning to create a mouth that’s wider than desired. You may make too many passes on the jointer when flatting the plane sole or file a bit too much when fine-tuning the mouth opening. Or, perhaps you’ve used your plane so much that the mouth has just worn out. Regardless of how it was created, it’s relatively easy to fix.
It wasn’t quite that easy for me because I wasn’t doing this on a Krenov-style plane; I was using a very old coffin smoother. It looked like this:
I don’t go through all the machinations of how I trimmed the insert, as it was difficult and time-consuming, and didn’t really apply to the subject plane, but I was pleased with the result.
