5' firs... wow such big ones are pretty rare in germany. everthing over 40" is big for us
I know you will have to laugh about that since you're from Oregon...
BTW did you have german at school or where is your knowledge about the language from?
We can't fall Fir that big here all the time, but they are about, for sure. Tree huggers and CAD-O-Files alike sometimes do not realize it only take about 60-70 years for a Fir to get around 3' in Diameter. At the entrance to the place where we were cutting are about half a dozen Firs about 4' in width. The one by the river fell on it's own due to erosion. That's always an issue by big rivers, and what's causing the Alders to start to fall as well. That and the occasional storm. Alder are very bouncy, so you really gotta pay attention when you are falling them. They also seem to enjoy barber chairing.
I have a minor in German from university, and my German family ties are originally from Bayern. So I do speak it with a southern dialect. Suits me fine, I am actually originally from Texas
There it is mostly cutting 1-3' pecan, oak, etc for BBQ smoke.
Back on topic. I think now some folks can see why PNW'rs would use square grind and take their rakers way down, It simply works for most of the wood we fall here, even ash and big leaf maple. I also like to thin the raker a tad by grinding the back of it(the side that faces the tip of the cutter) with a round file 10-15 strokes to speed her up a bit. Square also seems to hold it's sharpness longer in this wood. Or, at the very least, it's utility. In that video it's a 25" bar and semi chisel on an 066mag for firewood duty VS a 28" bar with a square chain set up specifically for that job site on a saw with 20 less CC's. I think it really shows the difference a chain makes even if that 372xp is particularly strong. To get an idea how that 066mag woulda done, just watch the 385xp in that video - I have the exact same B&C swapped on to it from the 372 for that video.
We had an abrupt end to that day, though. I hit a nail in the fir I was bucking and it absolutely destroyed the points on the chain. I am off to reground the damaged chain to round today. Six hours of messing with 70-90cc saws is usually enough anyways, so we just called it a day. I can say that I do appreciate the AV on that 385xp. Smoothest saw I ever cut with. It is easier to work with for hours than my old 046 ever was. But I am starting to get old...
