I have. Can the file be used to convert an existing round filed chain to hex? If so id try it out of curiousity. Trying to mimic a square ground chain?
It looks like some type of hybrid square ground. I have never tried square but it sounds like doing it must take a good bit more skill or patience and for whatever reason it seems when they con ery the round chain they have to file a good bit out? I have never read too close cause it doesn't intrest me that much as I don't race saws and want something quick and easy to sharpen or grind with minimal cost
X2. Maybe some day ill try cutting with square grind, but for now good old fashioned round filed done by hand works for me.
Maybe I'm not seeing the pic correctly. That file doesn't look like a chisel file. The GOOFY file was an attempt to attract more people to chisel filing . But the goofy file put up an awesome chain if used right. The Oberg file was kindof a goofy file. I wore out many of them . It was tough to get chisel files that actually lasted.
Did you ever try the Vallorbe's? The guy that introduced me to square chain, said Obergs were just double bevels with a straight cut instead of the angled that are prominent now. He also said they cut real smooth. The hexa file creates that straight chisel angle, which IME is more durable than what a round file leaves, which is similar to a hollow grind in knife edge talk. There is more material to support the working edge. The hexa puts that type of edge on the cutter for the average Joe who isn't square file savy. Goofy's created it on the top plate, but left the side plate round. I personally think the squared sideplate is a big factor in the smooth cutting character of square ground chain. Again, this is all just my .02.
Haha, no I'm a machinist, fabricator. Probably hovering around the 150 saw mark but I do have a screwloose. A roll of full chisel and one of semi then some 3/8 lp in each and 350' comes quick. I almost never sharpen a single chain, they get used and hung until I accumulate a bunch then I take a day and grind away. As far as frequency of use well it just depends on how I'm feeling because this whole wood thing is just a hobby.
I’ve never seen anyone file a chain with bar vertical, but seems like a great way to sharpen if you don’t have a vise available. He makes square filing look easy too.
Most of the guys who I see in the woods, my guys who work for my loggers file that way. They lean it against a tree and file like that.
