It is said that there are tricks TO
every trade, and nowhere is this 30 true
as II is in the matter Of radio set wiring.
Wiring a. radio set to many fans
means nothing more than finding tne
terminals that are to be connected ana
getting a piece Of wire connected De-
tween the points somewhere somehow;
usually, anyhow.
Tho result of such a method Of wir-
ing ia a set which may work, but which
must be kept covered up In a CABINET
to hide the poor Workmanship.
Such wire stringers are great aovo-
Gates of spaghetti insulation, for the
simple reason that unless some KIND OF
Insulation il used the whole works will
go blooey from short circuits Just as
soon as the batteries are connected.
II you want to wire up set whicn
YOU will be able to show to your friends
and be proud to claim as your nanoi-
work, Just decide right now that you
are never going to use spaghetti or any
other kind OF insulation on your wires.
/, benefits Outweigh Trouble.
This resolution will be rather hard to
keen at first when you are tempted 10
follow the proverbial advice that. a
raigbt line is the shortest distance be-
tween two points, but you will soon md
that the quality of your work and the
appearance of your wiring viii Improve
to the point where you will look tondiy
at II instead Of hiding 1t away where It
cannot be seen.
The first thing that you must learn Is
that in order to save time you must
spend time. In the first place, don just
slap the parts on Dashboard and panel
In any position that will make q lair'y
good appea rance on the front or the
panel without taking into consideration
the best arrangements for making the
necessary connections.
The best plan to + How is to place
your parts on Dashboard and panel In
an arrangement which at first sight
may seem to give you the desired ef-
feet, and which also seems to give the
best arrangement for wiring the ter
minalS together.
After that is done start tracing the
connections from your wiring diagram.
Usually, you will find that many Of the
connections are long and some connec-
tionS cannot be made without going in
and out around parts.
Sockets Should be Mounted.
AS you trace the connections you
will see where the moving of part
here and there will simplify the con-
nections without seriously affecting
the front panel appearance.
Whenever possible, sockets should
be mounted in a line and in the same
relative position. When this is done
the wiring of. the fiament circuit be-
comes a very simple matter because
straight wire running practically
the length OF the panel is all that is
necessary to connect the terminals
together.
The P and B terminals of trans
formers should always be placed near
the jacks with which they are to be
connected and the G terminals should
be placed near the G. terminals OF
their respective sockets The F ter
mipals should be placed SO that q
connecting wire from the negative
c battery can be run to them very
easily.
How to Wire Your Radio Set.
/ IT is just as important to choose a
good method of mounting the parts
of your set as it is to get them in
the proper relative positions for ease
In wiring.
to construct a radio set is to use q

always make a very neat-appearing
set when the mass of wiring is put

One of the best methods I know
of to make a real factory product
of a homemade set Is that which
