How to square file

Sharpened a chain that PA Dan sent up. She cuts niceView attachment 282666View attachment 282667View attachment 282668

Where's the video? I don't want to hear it's cold or snowy outside. You're young you can handle it! Happy birthday buddy!

Thanks Dan! With how that was set up, I thought it was gonna be very chattery.

What made you think that? Did it self feed well?

Thanks Dan! Ran out of cookie logs... I wonder why...... lol! Ill have a vid out soon.

It self fed very well. When I looked at the side plate there was a good amount of forward lean to all of them. I don’t feel like I have to drop the rakers one bit.

I believe I took a few swipes off them before I sent it. Ya it has some lean to it for sure. That's the same grind I gave on my 359 and it has been awesome. Has held the edge way longer than I expected. I haven't really cut any dirty wood though.

My tool isn’t super precise but you get the idea.

Hard to read from the photos. What are the numbers?

Thanks.

Isn't the important angle between the large flat face that would be getting the top plate and the smaller edge bevel not the 2 edge bevels? Of course you can work it out from what you have there but you're kind of measuring A to calculate B instead of measuring B.

The angle he’s measuring says the same thing though, just in a roundabout way.
The smaller angle of the vallorbe will give more forward lean

 

[Spladle160]

By my math the included angles made by the files are,
Bahco 127
Stihl 125
Vallorbe 132
A larger included angle would equal more forward lean for the same top plate angle and file tilt. Right? So you could potentially get the most aggressive chain with the vallorbe and least aggressive with the Stihl if all other things were equal which I'm sure they're not.

That’s how I saw it

Could not see on my 'smartphone' Blown up on the desktop I am reading (off the protractor):
Bacho 105°
STIHL 110°
Vallorbe 95°

You guys are a little faster than me with the geometry (dividing the angles, above, by 2, then subtracting from 180°).

Agree. Wish I had a better tool to measure and show. It’s not a large difference, but it is there.

It's gettin TekNickle in herrrre...

Spent some more time with better lighting and I believe the Stihl and Bahco are the same. I can't get it in picture, not enough hands.

Vallorbe likes a beak.

I had the impression that a beak was the opposite of what you wanted?

Little bitta beak can make for a fast chain, but it will suffer with durability. I would rather a little than to have the file too high and have "reverse" beak. Personal preference would be right on the corner.

I do like the two different angle references they showed in that video.

Finally got my hands on square file
But the only one i could find is goofy
Anyway, quickly grabbed an old chain and gave a shot.


First tooth ever, went a bit too low.



Another try, i think this one is a bit better.

And now, im hooked !

Any tips?
