The table is firmly bolted to the frame, and is fitted with the necessary groove slides and fences for rip sawing and cross cutting. It is also provided with a removable piece, which allows the use of wabbling saws, dado heads, etc.

The sides of this machine a, a, [Fig. 3099], are cast with an extension for countershaft. Referring now to [Figs. 3100] and [3101], the upright piece i, i, with arms b b, and g, g, is bolted to the frame as shown. The arbor frame m, m, is gibbed to t, t, by the circular piece u, and is moved to any angle by the hand wheel z, which operates the worm w, which in turn moves the arbor frame m, m. This arrangement does not require any locking device to hold the saw in position. As the centre upon which the arbor swings is in the intersection of the planes of the saw and table top, the opening in the table needs not be larger than for the ordinary saw. When cutting a mitre the saw takes the position j, [Fig. 3101]. When cutting at a right angle the saw takes the position j′ and the arbor takes the position p′ n′.
