I don't have any pics but I will try to explain. Sharpen your chain with your round file like normal. Jam a wedge between your chain and bar so your chain is tight in the bar. You are going to make your strokes into the chain rather than out like a round file.Put the corner of the file into the corner of the tooth and stroke down and in. You will remove some of the excess material from the top plate and out of the corner. This will make it cut smoother and somewhat faster. You will notice your chips look different if you are doing it right. Hope this does not screw you up too bad. It takes a little practice. I used this method quite a bit working in frozen pine which would take the edge right off a ground chain.
 
Frozen pine is almost as bad as standing dead oak with the bark off . Eats a chain like your in the dirt . Still haven’t learned to thrown on a loop of semi chisel “before “ a blunt out a full chisel in a half tank of fuel .
I have a factory stihl ground square chain . No matter how I hold that file it doesn’t seem to look like it’s hitting the same angles . I’m going down the shop in a few to take another look with my new glasses :rolleyes: maybe I’ll takes some pics . I haven’t looked at the square grind in a few years after I looked at the files I got and it didn’t look proper . It’s very possible I’m I high functioning Retard .... sometimes simple things don’t register in my brain when explained . Show me and I understand instantly
 
Thought about buying a Oregon grinder, have always hand filed but I'm not as good as I used to be and wondered about buying a grinder, suggestions please? Brand names, prices? Been looking on EBay
Thank-you
 
I missed this last night. The Stihl hex file has a smaller sideplate edge which leaves a considerably larger gullet & it won't work well for clearing them.


Why not ? As the file sits basically in the position to file the cutter. You file down and twist the file into the gullet. The flat takes out the gullet.
 
6 evenings a week filing 2 or 3 105-127 driver full or semi skip 3/8 or 404 . 6 to8 months a year. Till I got a grinder. That's what it takes to keep bushlin . My filing jig was a hard nose. 28" bar . With 4. 1/2 ton pick up leaf springs welded on for legs. And a stool to sit on. Hook the toe of my romeo into the belly of the chain to hold it tight and use 2 hands-on the file. When touching up a chain out in the brush . I always file on 1 spot on the bar up by the tip. But, filing out in the brush takes time. And time is money. At a dollar a minute , a guy doesn't want to waste too many minutes fooling with a chain . A chain swap takes a minute or 2 . And is a welcome break while I would get ready for my 10 minute lunch.

I have the Oragon ax and a usg . Both are wonderful . I predicted the usg . It’s just built better and is tighter . Have can wheels for both . They are worth every penny

Depends on type of grinding you want to do.

Round, anything with a metal base, that isn't from horrible fright aka hazard fraught aka harbor freight for sure a case of you get what you pay for.

chisel your pretty much down to Simmington for new stuff, or paying the same for a Silvey assuming you can find one
 
Looking good, now all we need is a log...
Just blew out a 16” chain in about 30 mins . It was round ground . Pretty easy to file oragon chain . I’ll try it out this week and see how it cuts . Looks like I’m getting into the side a bit much . I’ll have to adjust for that . But I’ll try it like it is for now . Me thinks it will blunt fast how it is . A1E414BA-C990-40AA-93B9-47A207C2B3CB.jpegA10EB9D9-21D6-4EC2-A540-DF37AFA0A528.jpeg

Your gettin there. You have a bit of an eagle beak on it . And you might look over the top of the cutters again to make sure they are Sharp.
But That is looking pretty good for getting started. It will be a bit grabby. If you were falling big red cedar It would feed well. Putting a humbolt in a hard western hemlock would be a challenge.
But all in all its good. Everyone that starts chisel filing has a ways to go before they are producing awesome chains every time.
 
Do you guys go a bit aggressive on the depth gauges ? I have mine set on the 16”at .25 . Usually I set them at .30 on round ground . I prefer my chains a bit on the aggressive side and self feed well . I don’t like using the dogs for anything but felling . Most of my cutting is bucking
