** Lubricating Woodscrews [318]

A screw may be turned into hardwood easily, by boring a small hole
and lubricating the screw threads with soft soap.

** To Make "Centering" Unnecessary [319]

For drilling a hole in a chucked piece, centering is just one
operation too many, if this method is followed:

First, face off the end of the piece, making a true spot at least
as big as the diameter of the drill. Put a center punch mark where
the tool lines indicate the center of revolution. This serves as a
rough guide for placing the drill between the tail stock center
and the work as usual. Clamp a tool in the tool-post and, on
starting the lathe, bring it in contact with the drill and keep it
firmly so until the drill is in fully up to the lips. This
prevents the drill from wobbling, and when once in true up to its
size, it cannot change any more than under any other starting
conditions. After being entered, the drill does not need the tool,
which should be backed out of contact.

** Fountain Pen Cap Used as a Ruler [319]

When it is necessary to draw a short line and there is no ruler at
hand, take

[Illustration: Ruling Lines]

off the cap of your fountain pen and use it as a ruler. If the cap
is fitted with a retaining clip, all the better, as this will
prove a safeguard against slipping.

** Vanishing Handkerchief Trick [319]

The necessary articles used in performing this trick are the
handkerchief, vanishing wand, a long piece of glass tubing, a bout
1/2 in. shorter t h a n the wand, and a paper tube closed at one
end and covered with a cap at the other, says the Sphinx. The
handkerchief rod, shown at C, is concealed in the paper tube A
before the performance. The glass tube B, after being shown empty;
is put into the paper tube A, so that the handkerchief rod now is
within it, unknown to the spectators. The handkerchief is then
placed over

[Illustration: Wand]

the opening of the tube and pushed in by means of the wand. In
doing this, the handkerchief and the rod are pushed into the wand,
as shown in D. After the wand is removed, the cap is placed over
the paper tube, and this given to someone to hold. The command for
the handkerchief to vanish is given, and it is found to be gone
when the glass tube is taken out of the paper cover. This is a
novel way of making a handkerchief vanish.
