Two man crosscut saw sharpening tools

Inc VAT. The answer is basically simple: chose a triangular file that is big enough so that all three sides will wear evenly as the file is rotated during the sharpening process. Measure the depth of tooth and select a file with a width that is slightly less than twice the tooth depth.

If you think it important to have a good view of the sharpening process, you might consider choosing a narrower file, with a width that is just a little more than the tooth depth. The file will wear out faster, but you will have better control over the work. Adequate light is also very important for this kind of work. If your eyes tire quickly, it is an indicator that all is not as it should be! Normal three-square files have sharp corners that cut a hard angle. Saw files have corners that are slightly rounded, so as to maintain the round gullet between the saw's teeth as you file them.

This is to help prevent cracking the base of the teeth, which is easy to do if you do not work carefully and precisely. Because of technical issues in the manufacture of saw files, there is a limit to how small the files can be made. Therefore we offer a small needle file to sharpen saws with extremely fine teeth. An alternative for very fine-toothed Western type saws is to use a small Japanese sword-form file, which also has a slightly rounded corner.

But you must then file both the tooth's front edge and back separately. This differs from using the proper triangular file, which will file the front of one tooth and the back of the previous tooth on the same stroke. The list is not exhaustive and multiple combinations are possible. These saw files are designed to sharpen traditional Japanese saws. Because of their narrow profile they are also suitable tools for working various very fine-toothed European saws and for many other types of fine filing work.

Produced in tooth size 2, saw files with teeth on both sides are designed principally for ripcut saw blades. Unless you are very careful there is a risk with crosscut saws that you cut into the backs of the close-set neighboring teeth. For these saws we offer Japanese files with teeth on one side which have been specially made for this job.

This configuration is designed to sharpen ripcut saw blades. With Ryoba saws, use it only on the ripcut edge of the blade. For saws with teeth on two edges of the blade, we recommend both types of saw file. This type of file is mostly recommended for filing crosscut saws including the crosscut edge of Ryoba saws.

You will soon, or possibly already have noticed that single-sided files cost a fair bit more than double-sided files. This is because these are highly specialized tools for which there is little demand and so they are produced in small lots by special order only. Inevitably this makes them more expensive. These files are remarkable for the incredible hardness of the diamond cutting surfaces. Unlike many of our files, they are supplied with a ready fitted handle as shown in the photo.

This traditional tool is suitable for jack saws and larger saws such as crosscut saws with a blade thickness of up to 1. The knurled screw on top lets you set the stop for the tip of the tooth.

This determines the position of the tooth where the anvil makes contact. Crosscut saws are unusually large tools intended for rough use, and so are not as carefully made, especially in the details, in comparison to better-quality traditional fine carpentry saws. So it is normal to find, for instance, machine marks and burrs on the blade and teeth of a new saw.

The burrs will fall off quickly when the saw is used, but we recommend that the teeth be touched up before use with a large saw file. This type of file is in any case very important to have when using these saws, as they must, because of the rough use they are put to and the relatively soft steel they are made from, be sharpened relatively often.

A mm-long saw file works very well on the One-man saws. For the Two-Man saws you use a flat file , as a threesquare saw file can damage the opposite tooth. Additionally you need this flat file for the deeper recesses near the raker teeth of the One-Man saw.

Tip: The saw blade should be at least twice as long as the thickness of the tree one would like to cut in half.

The teeth on these saws are designed for efficient crosscutting, and are not recommended for rip sawing. The teeth are set outwards from the blade to prevent it from binding in the wood, and so the kerf is larger than the thickness of the blade. Reading directions or safety instructions in a book or watching them on a DVD, for instance, can not replace personal and expert instruction. One should not go near this kind of work without a thorough grounding in the techniques to be used, and awareness of the potentially deadly mistakes one can make.

It is also often necessary to obtain a permit from the local authorities before cutting down trees. Thomas Flinn is better known for its fine carpentry saws, but has started to manufacture crosscut saws under the "Lynx" brand. The blade hardness is between 45 and 49 HRC, and is easy to re-sharpen with our mm-long saw file. Teeth cut and ground by machine Blade length 3 feet Now with supplemantary handle - see picture left!

This supplementary handle can be mounted at the nose of the blade for two-man use or near the main grip for extra leverage. Thomas Flinn is best known for the high-end saws designed for fine carpentry that they manufacture. But the firm has brought out a line of crosscut saws marketed under the "Lynx" brand. The hardness of the blades is between 45 and 49 HRC and can be easily resharpened with the mm-long file.
