(fig. 63). This tool, frequently improvised, is used for many purposes, and is accordingly made with every kind of blade. The particular router illustrated in fig. 63 is intended to reduce depressed portions of work to a level surface.

The router is akin to the planes in principle: a stout single iron (usually a piece of a broken chisel) is placed in a mortice through a block of wood, and, projecting as it does some distance beyond the sole, it scrapes as it were a fairly level surface in a place which is inaccessible to a plane.

Another form of router, which is very easily made, is shown in fig. 64.
