Save All Your 
Corn and Grain 
Keep It Clean 
and Dry 
Every bushel of corn and grain saved from waste is extra profit in your 
pocket. You may toil to raise a bumper crop, and then, through improper 
storage, lose a large part of it. 
Securo Corn Cribs and Grain Bins 
will prevent this loss. Neither fire, rats, mice, birds, insects, 
dampness nor thieves, can reach gram stored in Securo 
metal bins. They are easily erected, need no repairs and 
are just as cheap as wooden construction. A patented sys¬ 
tem of ventilation acts as suction, and draws fresh air 
through the grain, keeping it dry and free from mould. 
Let us send you our free, illustrated literature which tells 
all about Securo Corn Cribs and Grain Bins. Use the

Fitting the Circular Saw 
Will you give some instructions about 
gumming a common buzz saw used in saw¬ 
ing poles and cord wood? What method is 
used in gumming? Should the gullet be¬ 
tween the teeth be square or round? 
What is the proper outline of the teeth? 
Should the front side of the tooth he in 
line with the radius of the saw and the 
hack side be in line with the tangent of a 
circle proportionate to the diameter of the 
saw? My saw was originally 20 inches 
in diameter, but has been filed so much 
that the teeth are too short to work well. 
Trumansburg, N. Y. <t. h. g. 
Spring wood sawing brings on a variety 
of troubles, many of which might be 
avoided by the exercise of a little care. 
In cutting a "woodpile practically two cuts 
are needed for every stick, making the total 
sawing for a cord of wood approximately 
equivalent to cutting 700 feet through a 
one-inch board, or roughly a mile of such 
cutting for every eight cords sawed, and 
to add to the difficulties the material is 
often frozen and full of grit, so that it 
is little wonder that a saw frequently gets 
rie. 4

Methods of Filing 
Fa w Teeth 
The 
as a 
sulky before 10 hours of this is over, 
saw is just as much a cutting tool 
razor, and should be just as well fitted for 
its particular use. It should be so ac¬ 
curately fitted that each tooth should pare 
out of the kerf Its proportionate share of 
the wood, and carry out the dust. To do 
this the saw must he perfectly round, 
each tooth of the same length and filed 
to a keen point, for it is the point which 
does the cutting, just as when a knife 
point is scratched along a board. 
The first operation then in fitting a 
saw is edge jointing or making the saw 
round. To do this, put the saw on the 
mandrel, and revolving it at a low rate 
of speed carefully bring a piece of coarse 
emery or other abrasive against the edge 
of the teeth, and continue this treatment 
until every tooth has been touched. If 
little jointing is required to make the 
saw round so that the high teeth are 
ground off but little, the saw may be set 
as tlie next operation. However, when 
the saw is badly out of round and joint¬ 
ing lias to lie carried well down into the 
points of the high teeth it is usually better 
to file the teeth nearly to a point before 
setting. After setting is accomplished the 
teeth may be brought to a keen point by 
a few strokes of the file. 
Setting is the bending of alternate teeth 
to the left and right so that the saw 
makes a cut or kerf slightly wider than 
the thickness of the metal from which it 
is made, permitting the saw to run freely 
in the kerf. The set should be no wider 
than necessary to secure this free running, 
as a wide Set means cutting out more 
wood and removing it in the form of saw¬ 
dust which of course means more power 
and accomplishes nothing. Phis set, as 
stated, should be well up in the point of 
the tooth, and various devices are on the 
market for producing it. A complicated 
or costly outfit is not necessary however. 
The writer has had very good success in 
setting a small circular saw with one of 
tin* cheap anvil sets in common use for 
fitting cross-cut saws. The projections on 
the bottom of the anvil are driven down 
into the top of a sawed block of the 
proper size, and the saw laid in the proper 
position for setting with the point of the 
tooth just projecting over the ridge of 
the anvil. A spike is then driven 
through the mandrel bole of the saw, driv¬ 
ing it clear at the farther side in contact 
with the saw, so that the saw may he 
turned about it and each tooth brought 
successively over the anvil in exactly the 
same position as the first. Bolt nuts or 
washers are then put over the spike in 
sufficient numbers to make tin* saw lie in 
the proper position us shown by the 
sketch on this page. Every alternate 
tooth is then given a tap with a light 
hammer as it lies on the anvil, bending 
it slightly outward and after getting once 
around iii this way the saw is turned over 
and the remaining teeth set. It. is usually 
better to go over a saw several times in 
setting than it is to attempt to put the set 
all in at one operation. A more even set 
is likely to result. For smooth cutting 
the saw should lie side filed or dressed 
either by placing it on a flat surface and 
lightly running a file over the teeth, or 
by revolving it on the mandrel at a slow 
rate of speed while a file is held against 
the sides of the teeth. This evens up the 
teetli by filing off the points of any teeth 
that may have been set slightly more than 
others. Very little side tiling should be 
done or the set will he destroyed, only 
enough to catch the points of the teeth 
having too much set. 
The shape of the teeth will vary from 
Fig. 1 for soft woods, in which the front 
of the teeth is a radial line extending 
from the point of the tooth to the center 
of the saw to Fig. 2 for hard woods in 
which tin* front of the tooth if extended 
would fail considerably to one side of the 
center of the saw, reaching a point some¬ 
where between the center and the circum¬ 
ference. As indicated in the drawing the 
bevel should not extend the whole length 
of the tooth. Beveling the whole length 
of the tooth requires filing that might he 
better expended elsewhere. 
To permit the sawdust to circulate 
freely and to give the saw good dust car¬ 
rying capacity, the gullet of the tooth 
should be kept round as shown in Figs. 
1 and 2. The shape shown in Fig. 3 is 
recommended by a reliable saw company, 
II. Disston Co., from whom all of these 
cuts were taken, as it provides an abund¬ 
ance of room for sawdust and at the same 
time requires little filing for sharpening 
which is likely to result in its being kept 
in better condition. By all means avoid 
the condition shown in Fig. 4 as this, lie- 
cause of the wedging of the sawdust in the 
gullet, etc., is quite likely to result in a 
cracked saw blade. 
Special “gumming” machines with steel 
cutters are purchasable to round out the 
gullets of a saw 1o the shape shown, or 
a carborundum wheel of special shape is 
sometimes used for the same purpose." 
When a carborundum wheel is used the 
pressure must he light and the wheel fre¬ 
quently removed to avoid heating and 
after “gumming” in this way the gullets 
should be smoothed up with a file. For 
the ordinary small saw very satisfactory 
results can he obtained from the use of 
a rat-tail file of the proper size in “gum¬ 
ming.” Time spent in filing and fitting a 
saw is more than repaid in the increased 
amount of wood cut, lessened repair bills 
and lessened cost of fuel used in the 
motor. B. u. s. 
Fixing Gas Engine on Cement Floor 
I have a gas engine (3 II.P.) and a 
vacuum pump that I wish to fasten <>n to 
an old cement floor in my stable. There 
are 5x5 ft. skids on the engine; 3x2 ft. 
on the pump. I want to know how to 
fasten them to the floor without bracing 
from the ceiling, if possible. The fly 
wheels of the engine have about two feet 
clearance. Would you put the engine 
higher, and, if so, on wbat, and how inqch 
higher? I do not want to build an en¬ 
gine form or base of cement. c. S. v. 
Carthage, N. Y. 
Fastening these machines to the floor 
should present no great difficulty; the 
smoother and better construction the 
floor presents the more easily it can he 
accomplished. Set the machines up tem¬ 
porarily where it is desired to place them 
permanently, test to see that the belt runs 
properly, and when the correct alignment 
has been secured, mark down through the 
bolt holes in the bases by any convenient 
means, as a punch, for example. Now 
with a stone drill (the type known as a 
star drill is perhaps best), drill into the 
concrete floor for about four inches. 
These holes should he large enough to 
take the head of a holt, which is of the 
proper size to fit the hole in the base of 
the machine. If the drill used is not 
large enough for this the heads may be 
trimmed down with a cold chisel. Bolts 
of the proper diameter and long enough to 
extend from the bottom'of the hole up 
through the foundation of the machine 
and provide room for the nut are then 
stood head end down in the holes and 
after being ciwefully trued up so as to tit 
tin* holes in the base of tlx* machine, 
molten lead is poured around them, filling 
the hole. After the lead has cooled it is 
pounded by means of a blunt punch and 
hammer, which makes it expand, gripping 
the sides of the hole and making a very 
secure foundation. Melted brimstone is 
sometimes used for the same purpose, but 
the lead makes the more secure founda¬ 
tion und is very little more trouble to put 
in. 
To place the machine, pieces of board 
and plank can he piled up, making a tem¬ 
porary foundation upon which the ma¬ 
chine'is slid, the temporary foundation 
being made high enough to extend above 
the bolts fastened in the floor. After get¬ 
ting it properly lilted up with the holts 
beneath the pieces are removed, one at a 
time, and the machine gradually lowered 
onto the bolts. After letting the machine 
down to place it is leveled up and securely 
bolted in place. If the engine mentioned 
is in a clean place there will be little ad¬ 
vantage, other than convenience in start¬ 
ing and making the few adjustments that 
from time to time become necessary, in 
having it higher. If it is desired to place 
it higher, a built-up crib of plank may he 
used, and the foundation holts made long 
enough to extend up through. n. ii. s.
