THE YOUNG SCIENTIST 
Scroll Sawing— II. 
BY F. T. HODGSON. 
FIG. 7 shows a spring steel saw frame, 
which is a great favorite with some 
amateurs ; it will hold saws from two to 
five inches in length, and will face them 
in any direction, which is a great advan- 
tage, and makes this saw one of the best 
of its kind. Frames of this sort can 
be obtained that will take in a sweep 
of from eight to fourteen inches, for 
market. Fig. 9, will convey some idea as 
to the shape of this new frame, though

about one dollar, for the smaller size, and 
one dollar and fifty cents for the larger. 
This style of frame is, perhaps, the best 
in the market, as it is strong, neat, light, 
and efficient. 
Fig. 8 represents a Swiss saw-frame, 
but, as the largest of them will only take 
in about six inches of a sweep, they are 
not adapted for general work, although 
Fig. 8. 
where it can be afforded, they will be 
found very efficient in cutting out small 
designs, as they are easily adjusted, and 
the saw can be strained to almost any 
tension. 
Before closing this description of saw- 
frames for hand work, it will not be out 
of place to make mention of a very ingeni- 
ous device that has lately appeared in the 
Fig. 9. 
this is not the only one it assumes. It is 
made of spring steel wire about one 
quarter of an inch in diameter, and is in 
one continuous i)iece, the upper corners 
being turned double, and the narrow part 
of the handle twisted to hold it together 
at that point. The ends of the piece are 
sawed, so as to allow the saw to slip in. 
The saws used in this frame require to be 
turned on the ends to Jieep them from 
pulling through the slots in the ends of 
the wire. It has a sweep of about four 
inches, and can be purchased, with saw 
complete, for about twenty cents. The 
tension is obtained by springing the upper 
arm of the frame until the saw can be 
put in place, and when the w^hole is re- 
leased the frame will spring the saw taut. 
The next thing to be considered is some 
device by which the work can be held 
while operated on. Of course, the best 
device for this purpose, is a small carpen- 
ter's bench such as was shown and de- 
scribed in the Young Scientist last Octo- 
ber, page 126, but as most young people 
would prefer using an ordinary dining 
table as a base of operations, it will be 
necessary to describe how this can be 
done with advantage. Procure a i)iece of 
hardwood board — maple or walnut — about 
one inch in thickness, twenty inches long, 
and fourteen inches wide. Bore two holes 
through the piece, as shown in Fig. 10, 
one, about four inches from the end, and 
the other about three inches from the re- 
verse end. Cut V shaped notches up to 
these holes in about the proportion shown. 
The third notch is designed for very fine 
work and has no hole at the extreme end ; 
it will be noticed that the angle of the slot 
is very acute. On the end of the piece 
where only one notch is cut, will be seen 
a short stubby screw, the head of which, 
by the aid of a screwdriver can be screwed
