The saw will cut to the center ofa 32 inch circle . For cuts greater in length than prmittd by the 16 inch throat , the chucks can be turned 90 degrees so that unhrnited lends may be cut from the side of the ma - chine .

Saberblades are necessarily wider and heavierthan the fine jeweler's blades . Because of their more rapid cutting action they should be used for the majority of scroll saw operations .

Clamp a plywood sheet on the table , as an of the chuck . Move the guide post up to the top of its auxiliary top . Use a pin through the plywood as the travel , so that the quide and holddown are out of the center of the circle . The pin should be on a Iine drawn way . at right anqles to the flat of the blade even with the teeth , and its distance from the blade should be equal Only the smaller files will pass through the slot of to the radius of the desired circle . Drill a hole in the the table insert .

In the case practically any blade and is satisfactory for mast pur - of a round or square file this can often be adjusted by poses . Many operators prefer , however , to use sets of turning the file in the chuck . If a square position cannot special guides with rectangular notches to fit each be found , it is best to work from the side of the machine blade thickness . The set of six quides , No . 40 - 805 , offer - and tilt the table slightly so that it is square with the ed for use with this machine , is shown in Fiq . 5 . file .

It is useful for fin - cut and reducing weaving to a minimum . These spec - ishing the edges of work which has been cut on the ial guides are therefore valuable in the most accurate scroll saw or band saw .
