PATTERN MAKING 



51 



The single-arbor circular saw bench shown in Fig. 98 

 is a less expensive machine than that just described; but 

 the time lost in having continually to change the saw on the 

 single arbor from rip to crosscut and back again for pattern 

 work, is a very annoying as well as expensive inconvenience. 



BAND AND SCROLL SAWS. 



A good band saw, such as the one illustrated in Fig. 99, is 

 indispensable for cutting the curves and irregular shapes that 

 form a part of so many patterns. The best machines of this 



description have a tilting table 

 which can be set and clamped 

 at any angle, enabling the 

 workman to give the^required 

 level or draft to his work. 

 With a sharp and well 

 kept saw, there is no more 

 rapid or correct method of 

 cutting out and making cir- 

 cular core boxes of all sizes 

 whose length is within the 

 capacity of the machine. The 

 block from which the core box 

 is to be made must be cut 

 perfectly square on the end 

 that is to rest on the saw 

 table; and, if this end of the 

 block is not large enough to 

 give sufficient base to hold it 

 in an upright position, the

block can be supported against 



the blade of a try-square, or, better still, against a wooden bracket 

 made for the purpose. 



The scroll saw, illustrated in Fig. 100, is necessary for cutting 

 inside curves and openings in which a band saw could not be used. 

 Like the band saw it should have a tilting table. Where both saws 

 cannot be afforded, the scroll saw will take the place of both.
