How to square file

[p61 western]

I’m not that fast either, so I usually have a couple of extras with me.

I went through 4 chains on a fruitless mulberry. That was the end of square for me lol. Made me want a grinder really bad...

It sucks to touch them up on a job site. I'm just not fast enough at filing lol.

It's one thing to job-file a chain to get it to cut again. But then at home trying to get corners to line up again is another

Yep wrecked chains suck bad.

I try not to wreck my chain, cause if I do, then I have to lug rounds and stack. That sucks just about as bad as fixing a wrecked chain...

That sucks. I've hit metal multiple times millin' but I just can't give up on the smoothness and speed of square.

What's worse for me is filing away half the toof to get rid of the damage. That I hate! Usually end up phoning a friend with a grinder.

Lol need a friend with a grinder out here. I hit quite a bit of metal milling some oak awhile ago. It really sucks filing it on the mill.

We need a metal detector for milling lol.

Unfortunate when you find a pebble in the bark like that, but any full chisel chain will loose the corner just like that.

It takes a lot of filing by hand to correct damage like that. I generally bring extra saws with me (or would bring extra chains).

I would generally have a tooth like that ground down in round and then re convert it to square. If it is not too bad, I can do it with my little 12V grinder.

Just buy a diamond stone for it, the stones that come with them are crap.

Not the best picture, but I just learned how to post them-just gotta learn how to take them. Slight beak filed on purpose. Stays sharp, fast, but still smooth.

Here is my first attempt at square file. Any criticism is welcome. Sorry about the terrible pictures!
P.S. I am only using vanguard chain to train myself and I figured I would probably ruin my first chain, but I think it actually turned out decent.

Looks good to me. I like the slight forward lean on your side plate. Your inner corner may be a touch high for a long lasting edge, but it should cut great. Not sure if there is a slight side beak as well, as your pics are a little fuzzy. If you do have a slight beak it will cut great, but not last as long. I’m by no means an expert, and I’m sure there are more knowledgeable guys here that will chime in, though.
When I started square filing I posted up pics here and got a lot of good guidance.
You’re already ahead of most who start square filing, so you’ll do just fine.

I try to hit the strap that tells me I have the right angle.

 

[Mycamaro_68]

Thanks! Any advice is helpful! I will set the rakers to .025 as a starting point and see how it cuts.

 

[MustangMike]

IMO, the Mettee tooth looks about perfect, Mycamaro_68, I like to go 45*, 45*, 45* for hardwood (back, angle + down), your down angle looks kind of shallow.

Also (not necessary) but if you clean that gullet, it will improve performance.

By the way, this was Rex at the Humane Society. I wanted to adopt him badly, but he did not get along well with other dogs, and we had one, so it was a no go.

He was a really good dog, a mix of Pit and Mastiff. This is from Aug 2014, I walked him for years, but he has since passed.

He was 85 lbs of pure muscle!

Cleaning up trees pushed over by excavator. I like square filed chain for dirty wood. I reduce angles and lower depth gauges. Cut two tanks and a quick touch up for clean wood.

A little longer bar and the flare wouldn’t bug you.
