Reply To: Wooden fore plane – question about the cutting iron …. help!

It is also possible that the plane you have was actually put together from components from different planes. Blade length wear wouldn’t affect the wedge. It pushes the blade and cap iron in to the body of the plane.
Does the wedge show any marks / different shades from where it was assembled to the plane, and do they match to the plane body you have? If you match the marks to the plane body, do the ends of the wedge extend below the plane bottom?
You could do one of several things. Add some material to the edges of the wedge, so that it stops higher in the plane, or make another wedge that does fit, using the existing one as a template.
