Pacific/Hoe Saw & Knife Company

Chisel Tooth Saws

Chisel Tooth Saws The first successful Chisel-Tooth saw was invented and manufactured by R. Hoe & Company, Inc. in 1866. after 120 years, we at Pacific/Hoe, still lead the industry in chisel-tooth know-how and service.

A chisel-tooth saw, as manufactured by Pacific/Hoe is a precision crafted tool. It is a combination of special steel and skilled workmanship. True to our "Commitment to Quality" pledge, each chisel-tooth saw combines these elements and must pass through numerous quality checks before it is finally shipped to the lumber mill.

Chisel-Tooth Saw Characteristics

	Large, open gullets make these saws very economical as they can be made with a maximum hook that can be easily maintained.
	Chisel-tooth saws are made from highly tempered plate which permits more stiffness so they will hold their tension for a long period of time.
	Chisel-tooth saws always remain the same diameter. Replaceable bits and shanks protect the plate from wear resulting in longer life.
	Repairs are inexpensive inasmuch as damaged bits can be replaces while the saw is on the arbor.

Very little experience is required to maintain a chisel tooth saw. The bits can be filed quickly with a Pacific/Hoe #8 file designed for this purpose. If mechanical sharpening of teeth is preferred, the Pacific/Hoe Hand Filer using a disc or the Pacific/Hoe electric grinder equipped with an abrasive wheel can be used. When either machine is used, every tooth is sharpened exactly alike which means faster, cleaner cutting and increased production.

Chisel-Tooth Saw Manufacturing
Pacific/Hoe carries in stock all of the necessary diameters and gauges of material, either pre-hardened or in the "green" state. The steel plates are individually checked upon receipt from the steel mill for dimensional accuracy, flatness and hardness. Only the plates meeting Pacific/Hoe's standards for quality are accepted. The many operations necessary to produce a Pacific/Hoe Chisel-Tooth saw can be summarized in the three tasks of grinding, socket milling and tensioning

Grinding operations Grinding
Each saw is precision ground after each of the three hammering operations. This eliminates all hammer marks from the surface of the saw. Finally, each saw is polished to a smooth surface finish to reduce friction and pitch buildup. Our attention to precision grinding insures that you will receive a smooth, free-cutting saw for your mill.

Socket Milling
Sockets are milled and bevelled on computer controlled milling machines. As a consequence, the sockets are perfectly spaced. Additionally, by cutting both sides of the bevel at the same time, the bevel is exactly centered with the plate. If the milling operation is not done accurately

Hammering and Tensioning
A saw must be hammered a number of times during manufacturing. In the early stages, a saw must be hammered to straighten it and take out the uneven spots. Hammering for final tension comes after the saw is practically finished. This operation is perhaps the most difficult of all and requires exceptional skill. Anyone who has tried to hammer a saw knows how hard it is to stretch and loosen the plate in order to make the tension even throughout, or how one blow in the wrong place can ruin much previous effort. Circular saws revolving at high speed have a tendency to run loose at the rim. If not properly hammered a saw will snake and will inevitably heat at the rim or center. to overcome this, the rim of the saw must be put under tension. This is accomplished by loosening or stretching the saw in the body by hammering. A faster running saw requires more tension and the looser the body must be made. The diameter and thickness of the plate, the number and size of the teeth unserted, and the kind of wood being cut, all affect the tension a saw requires.

When a Chisel-Tooth saw leaves Pacific/Hoe, it has been carefully hammered with special reference to the conditions under which it is to be operated. If the information given us is correct, and the mill is in good order, the saw is guaranteed to run satisfactorily. If, after long use, or through some accident, it will not run true and requires hammering, it should be returned to us for proper adjustment as it is very difficult for anyone but an expert to hammer a saw properly.
