How to square file

[RI Chevy]

This was a 3/8 round file conversion chain. I am doing better, but still a long way to go. Chain was basically rocked by previous owner.

Here is how it cut.

I'll have to keep looking. I hate buying tools marketed for something specific when there is usually an industrial version that lasts twice as long for half the price. So the angle between the two cutting surfaces should have a minimal radius is what you mean when you say square right? Because the double bevel, triangle, and 6 side don't have 90deg corners between the side of the file that cuts the top plate and the side plate.

I'll have to wait till I either get a non cracked 372 crank case from huztl or a splined clutch drum for the China saw to do a 3/8th chain

You must've just done the dishes....

LMAO. I wore gloves. Good observation though!

It’s not 90 degrees but it needs to have sides <=>

The angle where the file faces meet should be greater than 90, maybe 120 or so

A triangle file is 60 so you won't be able to file the top and side at the same time.

Maybe you could butt two triangle files together face to face. That would give you a 120 degree angle.

Or just buy a grinder

There is no radius to a square corner

So no safe edges, blunt not tapered (or at least never use the tapered section to file with), and minimal radius. Cause there's got to be a radius on the outside edge of a cutting tool or there will be as soon as you take a cut with it.

Has this thread been infested?

 

[mdavlee]

The sides from the flat is what hits the side plate

Full chisel has an outside square corner

Kev, sounds to me like he is a machinist. When he says minimal radius, he’s probly think in thou’s

.325 isn’t that tough. I use a double bevel

I like that forward lean. It should feed real good.

What kind of chain is that? I’ve been using Carlton K1L for .325.

Looks like you need to do some dishes.

Thanks. Hopefully my little 40cc saws will have the stones to pull it. Lol.

Lol hopefully the rakers are tall.
