SANDING IN SUMMER AND WINTER.
How the Moisture in the Air Can Affect the
Quality of Sanding Work Through Soften-
ing the Glue Holding the Sand in Place—
Some Interesting Information.
The sand or grit is held in place on sandpaper
by glue, and this glue is affected by the same con-
ditions which will affect glue used in putting up
veneers. In other words, either heat or moisture
will tend to soften the glue. Heat will soften it
somewhat, and too much heat will burn, and an
excessive amount of moisture will cause it to
loosen up and release the sand. The effect of
temperature on glue makes it worth while to ob-
serve the difference between summer and winter
in the handling of sandpaper and sand belts. On
a moist, hot summer day the glue is softened, and
neither sandpaper nor sand belts will stand up
to the work as they should unless some artificial
means are resorted to keep the temperature down
and to dry out moisture.
On the other hand, sandpaper well cared for
should give its best results in cold, dry winter
weather, for then the glue will remain firmly set
and grip the sand tightly. It is then that one
may use the maximum of force or pressure in
crowding sanding machines and sand belts and
to expect to put through the larger volume of
work.
In the hot summer is ' the time when one
should go easy with the sanding and strive to
use clean, sharp-cutting paper and apply just as
little pressure as possible. Pressure to crowd the
work produces heat, and if the temperature in the
shop or factory is already between 90 and 100, it
does not take much additional heat to cause the
softening of glue and the pulling out of the sand.
What is regarded as the ideal condition under
which to get the best results out of sandpaper is
a low temperature and dryness, say a temperature
below 70 or 75. For this reason it is a good idea
to keep all sandpaper stock in a cool room and
not in some hot box of a room, where the tem-
perature may run up above 100 in the summer
time. This makes the basement a good storing
place, provided the basement is dry. To get the
cool temperature and have to take moisture with
it is not good. If you can get the cool tempera-
ture of a dry basement, though, it is the ideal place
to keep sandpaper stored, for then it will generally
be in good condition when you get a fresh piece
for use.
If there is evidence of moisture in the sand-
paper, it may be a good idea to subject it to a
comparatively high temperature to dry it out, but
when this is done, before using the paper, it should
be cooled off.
CALIFORNIA
REDWOOD
EXHIBITION.
An exhibit of California redwood, made up for
use, is on exhibit at the Country Life Permanent
Exposition, in the Grand Central Terminal. Red-
wood trees grow only in certain sections of the
Far West, chiefly in Mendocino County, Cal. The
tree grows to a greater height than any other
American tree, its maximum being about 350 feet,
and its greatest diameter 'JO feet. Most of the
redwoods cut are from 400 to 800 years old. In
the exhibit are pillars, fences, and portions of
house construction, made from pink redwood, as
well as mantels and hollow casks, railway ties,
water tanks, and foundations.
