How difficult is it to hand file this type of chain?

I would say not bad. Chains make chips and cut strait.

Take a few hours on a Sunday afternoon and you'll have the basics.

It isn't easy. You need the correct file (I like a double bevel) and to know how to get the angles right. There is tons of info on this site, but the tooth needs to end up looking like this:

It's best to first try it with a double bevel. Those 3-sided ones are :censored:

I've started to square my round chains and feeling comfortable about it. Once I worked out what to keep an eye on, they are coming out quite good. You can see as you are filing if your too high or low while checking occasionally from underneath. I'm left handed and feel quite comfortable changing from my left to right which I find helps immensely as far as keeping the chain even from side to side. My personal opinion is the you have more of a chance getting square right than getting round right without any guide.

Square is good for softwood but dulls quickly in dirty wood or in the dirt( can't tell how I know this)

Holy $#!T, I use a 2.5x or 3x OptiVisor, sounds like your using a Jewler's Eye...I guess that is for folks with long arms, file from across the room...

Once in a while I wear 1.5X or 2X reading glasses for filing. I find that Lighting is VERY important, shadows and dim light suck for filing.

Then it doesn't matter what grind you are using.

You would definitely get a chance to learn to sharpen square grind there! Id stick to round top or semi-chisel for areas like that. But thats my thoughts.

All of those things were in a big oak that I cut down. Broke 2 chains and destroyed the other. A friend bought part of a spool of chain at a auction. He paid 25 dollars for it. But it is the square ground chain.

You can roundfile square-ground chain, so don't let that hold you back if you can't file square.
I've been getting excellent, consistent results filing square chisel with a hex file chucked up in a Granberg File-N-Joint. Pics later when I get around to it.
Thing is, you want to have your angles trued up on a grinder every few filings no matter what, so this File-N-Joint trick may end up saving me a few trips to the shop in the long run. I file 'em by hand most of the time!

Where did you get your grandberg? Do you have to take the chain off the saw or is it a "guide" type?
