例文
I
have
had
a
chuck
of
this
kind
made
in
brass
with
the
cones
of
iron,
but
it
is
cumbrous
and
expensive,
and
does
not
answer
so
well,
owing
to
the
surface
of
the
iron
offering
less
resistance
to
the
work
turning
within
it.
This,
perhaps,
might
be
remedied
by
roughing;
but
I
think
the
chuck
is
much
better
in
wood,
as
it
can
be
made
by
any
common
turner
at
a
trifling

and
possesses
more
strength
than
can
possibly
be
required.

I have had a chuck of this kind made in brass with the cones of iron, but it is cumbrous and expensive, and does not answer so well, owing to the surface of the iron offering less resistance to the work turning within it. This, perhaps, might be remedied by roughing; but I think the chuck is much better in wood, as it can be made by any common turner at a trifling expense, and possesses more strength than can possibly be required.
