American Pattern File?

Postby trailcrew » October 4th, 2011, 2:22 am

I've heard several folks say that the best file for pointing up cutters is the "american" pattern file that is hard to come across these days. Is this what they are referring to?

The 8" Cant saw file is what I use on my rakers. The Simonds brand is no longer made. The Nicholson is all we have left availiable. As for the Cutters I use a 12" smooth FB with the edges ground to a 45, so it doesn't file on or mark the adjoining tooth. John

The American Pattern File has a teardrop profile. There is one listed on page 149 of the 1941 Atkins catalog posted in the database. I have been able to find some on eBay...John, are you saying that they are still available from Nicholson? I have scoured the web, thought they were extinct.

Thanks

American Pattern vs Swiss Pattern doesn't refer to the shape of the file but the way the teeth are placed on the file.

The teardrop cross section is for a Great American crosscut file and Nicholson still makes them. I got one new this summer at the Seven Corners Hardware in St Paul.

Some specs and a link: http://www.rsci.com/crosscut-great-amer ... -8593.html

Oh yeah, I always forget that those saws are the Great American Pattern, and the files are named accordingly. Thanks for the clarification, and for the link!

Do you mean a crosscut file? I purchased a dozen Portugese crosscut files from Warrensville File & Knife that worked pretty well, but WF&K has since moved that operation to India. I still have plenty of the Portugese files and have not needed to buy any new ones. Try a few of those India files and let us know how they hold up:

The Indian ones from Warrensville are great. Dolly Chapman brought some to UK with her. So impressed am I that I have secured the Warrensville agency for Britain and Europe. Refer https://www.shedtherapy.com/product/gre ... e-10-inch/

So glad you posted up here Gavin. I had been looking on line for a suitable file for a Great American and came across this post that took me to your shop.
