ibIs shaft end IS not making contact
with the rotating shaft Of the speedo-
meter AZ the ends Of both Of these
are flexible joints and IL the shaft

Slightly there VIII be 10 registration.
This is because the shaft in turning
does not turn the shaft in the speedO-

Home Made EIectromaEnet.
A simple six volt elecrromaEne for
Irecharglng magnetic magnets may be
made by winding about 800 feet on
No Is gage 3. & $. wire on two
one half by five inch soft iron cores
This design should give an intense
magnetic pull, for It contains about
10000 ampere turns and the strength
OF an electromagnetic is Independent
upon the number OF such turns. The
entire coil viii consume about ten
amperes at SIX volts.
Wiring Inspection.
One OF the inspections that should
be frequently made Is OF the wiring
system 10 see that insulation. con
facts. etc, are intact Especially IN
the one wire system poor insulation
7 VIII cause endless trouble, as in this
method OF wiring only one ground is
necessary to cause a short circuit.
ia making these Inspections each
wire should be traced from end TO
end and every intermediate contact
should be examined.
Thrust Washers.
Many cars are fitted with thrust
washers IN various locations and such
washers eventually become worn and
I occasionally the wear is rapid. This
IS due to a certain extent TO the fact
that no oil grooves are provided on
/ the washer and consequently when
oil tries TO make It's way to the face
, OF the washer, IL is squeezed out It
IS good idea to cut grooves IN the
1 washer, so that oil may be distributed
over the bearing surface and thus
prevent excessive wear.
I GearcaSe Lubricant.
During the colder half OF the year.
} gearcases packed with grease will
& cause gears 10 run practically with
out fabrication, because the grease
sticks 10 the walls OF the housing and
little II any gets 10 the gear teeth.
OH and not grease is the proper
lubricant for the gearcase at any rate
I during cold weather.

Fitting Shaft Bearing.
In replacing q bearing on a front
wheel spindle for which il is a tIeh-
III, the car owner sometimes Sins
me bearing on the taper end Of the
spindle and then uses the wheel a. a
hammer TO force il home. wheel and
bearing sliding into position on the
spln0le at the same time. This is
poor business as the strain on the
bearing may break the hardened
shoulder Of the inner race, which is
meant TO Withstand wear but not
shocks OF this kind The best way OF
accomplishing this work Is to slim 2
snort length or pipe over the spindle. ]
lhe inner end resting against the in
ner race or the bearing. BY hammer /

without trouble.
Water Control.
An effective, manual water control 4
may be made by removing the rubber
nose getween the top OF the cylinders
ana the radiator and replacing il with 7
meal one containing a shut-off .
valve OF the butterfly type. such al
are used on carbureters. A rod from
this valve Is extended through the
qash and enables the drive to reeu-
late the amount Of water fIowinp
through the system and hence to con- n
troll the temperature OF the engine.
Repairing Keyways.
When keyways become worn the
Iirst impulse Of the car owner Is 10 y
ne the channel evenly and fit a \
larger key. Often, however. the shaft 4
IS so small in diameter that fncreas- I
ing the size OF the keywav weaxers
the part seriously Some other meth
Cd Of repair must be sought. and
Welding Is the best way out OF tho
ciiiculty. In this process new metal
IS welded into the old slot and then
a new keyway is cut the same size as
the old one. The cost Of this opera-
ton is not important and the zevvay
Is Just as strong as It was originally.
