The Disston 1942 Saw Manual on Rip Saws

The rip saw is made for cutting with the grain. The teeth have an angle of 8 degrees on the front and 52 degrees on the back. The upper half of each tooth is set, alternately, one to the right, one to the left, to give clearance. This set on each side is equal to one-third or less of the thickness of the blade.

Disston Rip Saws 5 1/2 points to the inch and coarser are made with finer teeth at the point of the blade to make it easier to start the cut. The teeth of a rip saw act like vertical chisels, each tooth chipping out a small portion of the wood from the kerf.

 

How to Use a Rip Saw

The position for ripping should be such as to permit long, easy strokes. The user who does most of the cutting with a few inches of blade, in the middle of the saw, has difficulty in keeping the line of the cut straight. He also dulls the saw more rapidly, because a few teeth are called upon to do all the cutting. Full strokes are desirable in both ripping and cross-cutting.

In ripping, the cut should be started with the finer teeth at the point of the blade. Ripping usually is done with the work supported on saw horses, but if the board must be held in a vise, place it to give the proper cutting angle.

An angle of 60 degrees between the edge of the saw and the face of the work, as illustrated below, [illustration is to the right here] gives best results when using a rip saw.

Disston Rip Saws cut with extreme ease when kept properly sharpened. It is not necessary or desirable to force them in the cut.

No saw can be expected to give good service indefinitely without resharpening. Owners claim Disston saws require less sharpening than others and when sharpened, retain their keen edges longer. In ripping and cross-cutting, it is good practice to cut on the waste side of the line instead of trying to halve the line.

 

 

Disston Rip Saws are made 5, 5 1/2, and 6 points to the inch in 26-inch lengths and 7 points in 22 and 24-inch lengths in some patterns. The 5 1/2 and 6 point are most widely used for general work.

 

Length of Blades

The length of either rip or cross-cut hand saws is measured from point to butt on the cutting edge. Both cross-cut and rip saws are made in various lengths, the 26-inch being the most popular.

Some patterns of Disston cross-cut saws are made with blades 20, 22, 24, and 26 inches long; and rip saws with blades 22, 24, and 26 inches. Saws 24 inches and shorter are known as panel saws. The 22 inch, 10 point cross-cut saw is most popular among the shorter saws.
