How to square file

[Duane(Pa)]

Just curious as to why square file chains seem to make bigger chips than a round filed chain.
Is it just me, or is that the norm?

Nature of the beast. Cut through vs. grind through the fibers. Sort of like a plane vs. a rasp.

Ahhh. Makes sense then. Thank you sir.
I just wanted to check to make sure I wasn't doing anything differently. As in wrong. Lol

Artisan wood workers study wood structure and composition. Each piece of a jewelry box might be hand selected for just the right alignment of grain in a fancy joint or on a surface. I guess the point is, that they study fiber cutting efficiency too.

Here again, I'm the dude that thinks a dead barkless tree is a work of art. That, and I shoot rabbits...

Rabbits taste like chicken, only better!

While in the garage today, I remembered you asking for pics of the double bevel file adapter barrels I turned on the lathe for the newer style file n joint or Oregon guide. Here they are

That is what I need; the bushings not a lathe. I ground down some aluminum cable stops with a drill and the belt grinder, then drilled and tapped a set screw hole. Worked only fair due to file length. Tonight I thought I had the left cutter angles worked out so I rotated the file for the right cutter and one of the bushings fell off never to be seen again. Your larger bushings and the flat file look a lot easier to set the angle. Maybe I can talk a local machinist into making some for me.

What files are you using?

Vallorbe seem to be better, but difficult to find

You can also get an older granberg 106 (I think that's the model) or an older Oregon with the triangular shaped file holder. It's already at a decent angle for a double bevel file. No bushings required

I missed that you were using a 3 corner file. My #'s were with a double bevel like Kevin linked above. & I think I had the chain stop fully extended as well.

I have read that the 107 was made for square filing, but finding one is tough. I have a 108 and it is basically triangular but it doesn’t hold the small triangular file very well. Will the 6 sided flat files fit?

If it's like the last pic I posted, yes. I had to grind about .010" off the width on both sides on the wide end of the double bevel file.

The 108 holds the double bevel fine.

Thanks. I was just putting choos on to go out and get him a better pic of the triangle shaped ends. Ain't gotta now

How are you guys making the front of the rakers flat?
Just clamping them in a vice grip and filing them?

I clamp it at the edge of my chain vise and use a cutoff wheel
