How to square file

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!

 

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

 

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.
