Never use %sandpaper on any surface
on which 1t will afterwards be neces-
sary to use q plane or scraper. The open
grain or pores of the wood will be filled
with the fine particles Of sand loosened
from the paper, and these hard, fiinty
grains will destroy the keen edge Of the
scraper or other sharp tool. See to II

scraped smooth, and then, at the last,

sandpaper.
Sandpaper is made in many grades,
from No. 900 very fine. to No. 3. which
Is very coarse. For wood work Nos,
90, O., ", 1, ~ and 2 are the only grades
used. %Sandpaper is made very cheaply
by machinery-a roll of strong paper
passing over a revolving brush. on q
large glue pot which coats its surface
with glue, after which 1t is carried by
rollers under a distributing box of fine
sharp sand Of the required grade. The
sand adheres to the glued surface and
the paper is next dried by passing over
heated rollers. 1t is then cut into sheets
OF made up in rolls for the s%andpaper
machines.
Magazine Rack.
In Fig &C is given an illustration Of
a magazine rack. which, as was directed
for former articles, should be made first
of pine, so that it's construction will be
understood and some practice gained in
the use of the bow saw and cabinet file,
before making it of quartered oak. AS
magazines are about seven inches wide,
the rack may be made % inches or 20
inches between the sides, or even longer
If desired.
Having decided on the length Of the
rack, a stock bill" or list of the pieces
required, should be written out. This
will prevent many mistakes and enable
the worker to use greater economy In
laying out and in cutting up his lumber.
The projection of the front and back
strips over the two sides, as shown in
Fig. 66, is one-quarter inch, and the
thickness of the sides and of the shelf
is one-half inch. II the rack is to be 90
inches long inside, our stock list will
read as follows-all sizes being net, and
always in inches:
pieces 81 by 3hxH-sides.
l piece 29x3hx1a-shelf.
3 pieces 3Okx1hx&-strips for back.
3 pieces 3Ohxlx5-16 or A-frons
strips.
When marking off the above pieces
on the board from which they are to be
sawed, mark each piece on%e-quarter inch
wider and one inch longer than rha
above net sizes. This is the extra allow
ance for saving and for planning to di.
mansions. However we'll the lumber
may have been planed by machine in the
planning mill, it must be replaned by
hand to remove the marks OF the revolv-
. ing cutters of the planer.
Having sawed out the nine pieces nee.
essary for this rack, with a plane dress
each piece to the sizes given in the
stock list, then cut off each piece to tbs
net length and plane and smooth the
ends of the pieces. Should any surface
be cross-grained and rough, II must be
scraped smooth.
, The two sides must next be laid out
!, as shown at A in Fig. CT. In this desig,
