Chisel grinding and fileing. NOT SQUARE !!

[tramp bushler]

Just a big pet peeve of mine.

There ain't nothing square about chisel fileing or grinding.

Calling chisel grinding or fileing square as opposed to round fileing is quite a dumbing down of a group of people not known for bright intellect.

I don't know why Madsen's called it square. There is nothing square about it.

are ya peaved cause the angles on a full chisel chain are not in fact 90' to one another?

I mean, its a bone to pick I guess, but I can think of better reasons to loose sleep and or stomach lining

Might be because Oregon does other then that no idea why it's called that. My question has always been how do you get a chisel from a round shape?

For decades , while both hand fileing and grinding chisel chain. As did every other bushel in camp. But, I never heard chisel grinding or fileing called square until fairly recently. Like the past 10 years or so.
A , Square is a real thing . its absolutely, perfectly , precisely 90° .
About the only thing that might be 90° on a chisel bit cutter is the out side angle of the side to top.
And I've NEVER dressed a stone or used a chisel file that was square . Or put anything square into the tooth.

Most of the fallers i know call it chisel bit chain ,it is easier to say square or round rather than explain what a chisel bit chain is every time. Stuff is more triangle than square now that you point it out,not my best work but a random .404 work chain I had.

I sent them an email.

The original was chipper tooth configuration. Then they started making the chisel tooth.
Most of the old timers that broke me in and that I cut for . Started with 3/4 or 5/8 pitch chisel filed chisel bit.
I learned on Oregon 52 AJ . full skip 404 . But I was round filing chisel bit chain when I was a teen aged back east.

I always figured the distinction was between round-filed chisel and square-filed chisel. Same cutter, different file. Different grinder, too. Now that I think about it, while it might be a bit misleading to call it "square", it's still an important distinction and saves a bit of miscommunication.

 

[bitzer]

I thought it was hip to be square

 

[CR888]

Round ground chisel & square ground chisel are essentially the same cutter just ground different, they are BOTH chisel teeth/cutters. Chamfer, semi chisel & chipper are much different cutter designs. Madhatte above gets it.

I always took "square" to mean filing to the flat edges of the top and side plates which are square to each other.

For years I used a flat Oberg file for filing chisel bit chain. Nothing square about it. If you are filing right, you will just about have the tie strap filed in two when your chain starts throwing teeth. If anybody knows where there are some Obergs, I'd appreciate that info. I think chisel filing is a bit of a lost art.

Pferd had some files that where ok... (German for horse... also they where hard to locate 3 years ago soo...)

Otherwise i think your stuck with Oregon

My favorite file is a double end Oberg chisel file. They held up 3 to 1 over the Valhalla brand files. I've never used a Save Edge brand file to the best of my knowledge.

Ya, this square thing drives me nuts.
Heck o billy. Chisel bit chain was termed after a wood chisel.
I got several wood chisel and ain't a one of em any kind of square.
I wonder if Oberg went out of business ?
That would major Suck !

Hey Bob, how you doing ???

Great to see everyone from the old Long Bar Association coming thru.
Where's Randy Mac ?
Is Jacob still around ?
Any signs of Burv?

Does Oregon make chisel files ??
I need to get some goofy files.

 

[northmanlogging]

I think so?

Bought a grinder a few years back and haven't filed a chain since

Well except my climbing saw, cause its to small to grind.

They make 'em, sort of. They buy them in bulk from the same Brazilian vendors as everybody else. A few Swiss outfits still make their own -- Vallorbe? -- but mostly files are a commodity item these days.
