** Repairing a Broken Phonograph Spring [316]

As I live a great distance from a railroad station, I did not care
to pay the price, and await the time necessary to deliver a new
phonograph spring to replace one that broke in my machine, and I
repaired the old one in a creditable manner as follows:

I forced the two ends of the break out where I could get at them,
then heated each end separately with a pair of red hot tongs and
turned a hook or lap on them the same as the joints in knock-down
stovepipes. When the ends were hooked together, the spring worked
as good as new. The heated portion did not affect the strength of
the spring.

** Calls While You Are Out [316]

If you wish to know whether or not the door or telephone bell
rings during your absence, place a little rider of paper or
cardboard on the clapper in such a way that it will be dislodged
if the bell rings.

** A Small Bench Lathe Made of Pipe Fittings [316]

The most important machine in use in the modern machine or
wood-working shop is the lathe. The uses to which this wonderful
machine can be put would be too numerous to describe, but there is
hardly a mechanical operation in which the turning lathe does not
figure. For this reason every amateur mechanic and wood-worker who
has a workshop, no matter how small, is anxious to possess a lathe
of some

[Illustration: Fig. 1-Details of Lathe]

sort. A good and substantial homemade lathe, which is suitable for
woodturning and light metal work, may be constructed from pipe and
pipe fittings as shown in the accompanying sketch.

The bed of this lathe is made of a piece of 1-in. pipe, about 30
in. long. It can be made longer or shorter, but if it is made much
longer, a larger size of pipe should be used. The head-stock is
made of two tees, joined by a standard long nipple as shown in
Fig. 1. All the joints should be screwed up tight and then
fastened with 3/16-in. pins to keep them from turning. The ends of
the bed are fixed to the baseboard by means of elbows, nipples and
flanges arranged as shown. The two bearings in the headstock are
of brass. The spindle hole should be drilled and reamed after they
are screwed in place in the tee. The spindle should be of steel
and long enough to reach through the bearing and pulley and have
enough end left for the center point. The point should exten
