edger

An edger, Fig. 118, is then run around the outside edges of the block to round them.

Now the work I am doing here is running a gauge edger in a saw mill.

As this became a tiresome task, I constructed an edger, as shown in the sketch.

By stripping the concrete while it is still pliable the edges can be worked down by the ordinary cement sidewalk edger.

A gang edger consists of an arbor driving two or more circular saws, through which the boards to be edged are fed.
