This is done, as already described, by the regular soft wood turners
in Tunbridge and elsewhere, by means of hook tools. A great number
of workmen, however, use only the gouge, and for boring out chucks,
hollowing boxes, small bowls, and similar work, the latter tool will
be found effectual if rightly held and carefully managed. It must not,
however, be applied to the inner surface of the work at the point
usual with scraping tools, but beyond the centre, Fig. 109A. The
rest, B, does not require to be turned across the face of the work,
but remains parallel to the bed of the lathe. The blade of the gouge
is to press against the near side of the hollow as the work proceeds,
which considerably aids in securing the position of the tool. The back
of the gouge is to face the bottom of the hollow (next the mandrel),
but the tool is generally rolled on the rest a little, so that its
hollow side is often more or less below, towards the lathe bed, and
the point is also lightly raised as it approaches the finish of the
cut. Begin with the tool almost horizontal, and at the centre of the
piece, the back against the wood, and, depressing the handle as the
shaving is removed, finish at the top _outer_ edge of the hollow,
rolling over the tool, so that it shall leave the work with its back
upwards and hollow downwards. Thus used it will not stick in its
course, and, after a few trials, will be found to cut out the wood
cleanly and rapidly.

Another grip chuck, or self-centering scroll chuck may here be
introduced, from the source of information previously alluded to. The
writer thus describes it--
