This is actually a copy of an Oregon product.
Don't toss it,I'll pay freight to try it.Never see them around here.
It will be good to hear your progress. I’m surprised to hear you need to mess with gullets with a round grinder. You might experiment and see how they function when you don’t once you get it dialed in. I seen on Amazon they have a decent looking stand if you have the room, makes it nice
And what kind of stone do you have that doesn’t need dressing? Heard of a diamond stone but I guess they don’t produce a good chain
I'm using regular pink oregon aluminum oxide stones now, they need dressing.
I have a 3/16 CBN wheel coming. CBN does not need dressing and never changes size or shape. They're supposed to be good for 1000+ chains before you have to recoat or replace them. They cost about 3x an Oregon pink wheel, or 10x a bargain basement wheel.
From what I've read, diamond wheels are meant for carbide chains only. They cut too slow and make too much heat for general use (but also need no dressing). More info here
Carbide chain sounds interesting. Are they used on the big harvesting machines?
I've seen some folks say that carbide chains are meant to cut through metal impregnated wood or whole metal structures, but I also read about carbide chains breaking off cutters. I guess there are three different types. According to my *limited* research carbide also can't hold as sharp an edge as steel. This is very interesting to me because a chain that would stay sharp 15 times as long would make my milling operations go much faster. Even just having a nice durable chain that can rip through dirty bark or handle metal fasteners would be great.Not sure about the big stuff, but you can get carbide chains for regular saws. They're for dirty applications, ash in the bark, or where the chain needs to go a long time between sharpenings, or applications where you expect to hit metals (fire departments, fenceline felling, etc).
The price you pay is that it's more expensive (2x and up) and you need specialist equipment (diamond grinders) to sharpen it.
That said, a diamond round file is like ten bucks now if you want to hand file it, and a diamond grinder wheel is about the same price as a CBN one. (You need both to do steel and carbide chains, so probably not many firewood cutters have a diamond wheel handy.)
