certain rules that will assist the operator. In
the first place fluted drills are better, in the
main than twist drills. as the latter are liable
to gnp in the work and break of, especially
in drilling a piece Of thin metal. The drill
should be sharp; blunt drills mean great ex-
ertion and little accomplishment. while a sharp
one requires only moderate pressure. Brass. gun
metal and oast-iron are best drilled dry. Wrought
iron and steel call for . little thin oil on the
drill point Some sorts Of wrought iron are
exceedingly hard, so that the drill makes little
impression at first. Thy making 4 deep center
punch mark before applying the drill When .
large hole is 20 be bored. II Is q good plan first
to drill . small hole to act as q pilot to guide
the larger drill.
Sighting the sight Feed.
II for any reason it is difficult to observe
the rate q flow through the sight feed oilers
mounted on the dash. try slipping 4 bit Of

glasses win show with considerable dissfnctness
even in a proper light
Metal Saws. 4,
The metal saw Is Z mighty handy garage tool,
but there are certain things to remember in n
use Tho steel blades are brittle and easily
broken unless the saving operation is properly
carried out For iron and steel. fine toothed
metal, eoarser ones are advisable. Before ssw.
ing make true circumferentiM line around the
tube, where the cut s desired. Then by turning
the tubs around a little between each cut. the
operation viii be straight and true. incidentally
broken saw blades are useful for various small
repairs.
Homemade Clips.
A valuable supply to keep around the garage
is few feet Of thin soft iron strip. Of the sort

factory clips. Fastened in place by means Of q
couple Of SIG inch round headed bolts with
square nuts, said bolts to be Of different lengths
Bending Copper Pipe.
The motorist who likes TO carry out his own
to face with the difficulty Of making a sharp
bend in a piece Of copper tubing or pipe. For
anything over SIG OF an inch in diameter, the
pipe must be temporarily filed with lead OF
sand Il is possible, however. TO make very
fair bends in the ordinary copper tube by heat.

which it is bent very gradually round a bar
held in a rise The amount Of construction will
be very slight, especially after touching up with
ball-pein hammer. If this method is carefully
carried out.
Emergency Connection.
Il is possible to make a very acceptable con,
nectiOn for ths end Of electrical wires, by
slipping the bare cable ends into a small piece
Ot copper tubing Of suitable size, which Is
then pincned in the yiss TO give q good gnp
Of the wire ends. Next the end Of the copper
tubing is spread by hammering. a hole is drilled
or punched in the center and an open pathway
cut through to make the connection detachable
without taking of the terminal head.
valve Repair.
II frequently happens that the valves become
short in the stem from constant hammering and
IL the tappets are not adjustable, proper valve
opening Is lost. To remedy this condition, drill
4 small hole up the valve stem and file a steel
peg that may be driven tightly into this hole
Drill and counterank 4 hole through q piece
Of steel strip and riTet II into the stem by
means Of the projecting bit Of steel pin. Trim
of the lob with a file. Another way to the
same end is to drill and tap a small hole up the
stem and screw in it a small steel bolt.
Emergency Cement.
In the absence Of the regular product it is
possible to make fairly satisfactory tire ce-
meut by dissolying rubber faxed of into small
bits in gAsolene or benzine. When the need
justihes desperate remedies. enough rubber may
be carefully Whitfield off a spare casing to make
small amount Of cement
