Jointer Planes: Flattening Large Work

Jointer planes (No. 7 at 22" and No. 8 at 24") are the longest bench planes. Their length bridges hollows and high spots, cutting only the peaks until the surface is perfectly flat.

When You Need a Jointer

For edge jointing boards wider than 6 inches, flattening tabletops, or dimensioning rough lumber, a jointer plane is essential. The long sole provides a straightedge reference.
