=Polishing in the Lathe.=--The lathe is of more use to a polisher than a
great many persons outside the trade would imagine. By its aid turned
work can be finished in a most superior style, and in less time than by
hand. The articles usually done by the lathe are wood musical
instruments, such as clarionets, flutes, etc.; also cornice-poles, ends,
and mahogany rings, the latter being first placed in a hollow chuck and
the insides done, after which they are finished upon the outside on a
conical chuck. For table-legs, chair-legs, and all the turnery used in
the cabinet-work, it will be found of great advantage to finish the
turned parts before the work is put together.
Most of the best houses in the trade finish their work in this way,
where all the work is polished out entirely with the rubber. In the
first place, the filling-in is done. The band is thrown off the pulley
and the work rubbed in; at the same time the pulley is turned round by
the left hand. When this is done, the band is replaced and the work
cleaned off with rags or shavings, the lathe to be driven with speed to
get a clean surface. When applying the polish the lathe should revolve
with a very slow motion.
The rubbers best adapted for turned work are made of white wadding, as
the hollows and other intricacies can be completely finished out with a
soft rubber. The work should first receive a coating of thick shellac,
two parts by weight of shellac to one of methylated spirits, and applied
with a brush or a soft sponge; after a couple of hours this is nicely
smoothed with fine paper, and the "bodying-in" completed with the soft
rubber and thin polish. There are numerous hard woods which do not
require filling-in, amongst which may be mentioned boxwood, cocus,
ebony, etc.; these may be rapidly polished in the lathe, on account of
their texture, with the white polish. In spiriting-off a very soft piece
of chamois leather (if it is hard and creased it will scratch) should be
damped with methylated spirits, then wrung so that the spirit may be
equally diffused; the lathe should then be driven at a rapid speed, and
the leather held softly to the work. In a few minutes, if a dark wood, a
brilliant surface will be produced.

_CHEAP WORK._
=Glazing.=--Glaze is known to the trade under several names, such as
slake, finish, and telegraph; it is used only for cheap work, when
economy of time is a consideration, and
