What it’s used for

Lie Nielsen router plane

Tidying recesses

Router planes are used for trimming and levelling the bottoms of joint recesses such as shallow mortises and dados (housings).

Tidying up stopped housings with a router plane It planes the recesses to a uniform depth and can work into corners that could otherwise only be reached only by a chisel. Wood routers are best used in conjunction with router tables.

Characteristics

Cranked iron of a router plane

Cranked blade

The irons, or blades, used in router planes are distinctive – they fit vertically into the plane, but are cranked at the bottom so the cutting edge, which is always bevel up, meets the wood at the correct angle.

Bullnose configuration

To add versatility, some router plane blades can be reversed so that the cutting edge can reach right into the corner of a recess that stops short of the end of the wood.

This is known as the “bullnose configuration”, because of its similarity in use to a bullnose plane (see What is a bullnose plane?)

Routed by its lookalike

Unfortunately for the router plane, this popular power tool, due to its speed and versatility, has more or less replaced it in today’s workshops.
