How does this work?

[Tom Wiarda]

I see these quite often at flea markets. I know it is for use with a file for jointing saw teeth prior to sharpening but I have never seen one in operation and cannot figure out how the file attaches and how it works. Please post a picture of one in operation or a short tutorial on its use. This one is made by Atkins with patent dates from 1874 to 1888. Thanks

These are used fpr sharpening loggers saws..
You use it to file rip teeth down to a set size using the paper shims are the setters..

Its hard to explain but I will try with out pics..

You have four teeth one is set left, next two are rips one facing front one back and the last one is set right.. The lefts and right slice corners deeper than the rips.. The rips clear out the wood sawing forth and back while the slicers make cuts at the corners severing the wood fibers...

I would post a link to how to sharpen a loggers saw but fear the Admin will delete the post like he has the other I have made in the past few months.. He told me posting any links that SMC has paying adverstiments for to websites with products that the linked site may also sell will be deleted..

Hope this helped..

Actually they are for filling the drag teeth, no set in them, to a height just under the height of the cutting teeth.

You place the tool over the drag tooth, thru the small slot in the center and on top of the cutting teeth holding it up so you can use the file crossways across the top to lower or joint the raker teeth before filing the V in the center of the tooth.

Raker teeth, rake the sawdust out of the kerf, but do no cutting, and have no set, they are filed straight across with no fleam angle. Also notice the size of the gullets on each side of the raker tooth to accomadate a large amount of sawdust when cutting a really large size log.

On this particular tool, there is a screw that holds the depth guide to the body and it has 2 pieces of thin cardboard under it to space it the right height, others have an adjusting screw on the bottom to do this, such as yours does.

This is the proper file for sharpening a two man saw.
