Fig. 155. The gouge
"What tool is that?" asked Harry.
"The gouge ground or bevelled on the outside." ([Fig. 155].)
"What is it used for?"
"For cutting concave curves, especially those below the surface. Suppose you practise on a piece of white wood."
A piece of white wood was squared up, a foot long and 11⁄2 inches square. The lines shown in the figure were laid out with the pencil. The marking gauge is not suitable for this work, as it makes a sharp cut in the surface just where the edge is to come, so that after the gouge work is finished, it would show this edge split by the gauge mark. ([Fig. 156].)
Fig. 156. Practise cuts with the gouge
The two grooves from end to end were first cut, removing a quarter circle, the curve being drawn on the ends by a pair of compasses or dividers. This gave excellent practice in freehand work, calling for good control over the hands, and a constant watching of the grain to prevent splitting.
