Did you ever figure out why your 066 will out cut your 029???:monkey:

larger engine and bar? pro saw versus mid range? higher revving

3/8 chain has bigger cutters so they stand more sharpenings than 325.
It also has less cutters so theres less to sharpen.

I was up where Sawtroll lives just last month, and I can confirm that it is indeed cold where he lives, however the cold is only part of it, the big problem for me was the lack of daylight, it is pitch black by 2pm! No sun at all now.
Tromso was not that bad cold wise, but we went up into Finnmark which extends right over to Russia and it was -15c when we called into a town called Kirkenes.
It is dry cold though and doesn't seem to me to be as bad as the high humidity damp cold +8deg here.
I like Norway but would prefer to have visited in the summer TBH.

If chain speed is the advantage with 325, then 325 NK must be even faster?

nk??? narrow kerf? like picco? if so i would assume it would
Lets get this straight, 325 has less chain speed than 3/8 but more torque due to the lower chain speed and will cut faster in bigger hardwood with the same power. This high chain speed is just BS in real life. Steve

I actually tried 044 with 18" 9 pin 325" before. I didn't time cut but probably little bit slower than 3/8 with 8 pin which is about the same diameter. I think the problem was the cutters couldn't remove enough chips fast enough. I remember it stop cutting to discharge the chip in the middle of cut.

With both 325" & 3/8" with 7 pin rim, 325" rim is smaller so I would think the chain speed would be slower. Yet with more cutters to remove more material to make up for the speed.
It is due to the torque applied to the chian is why 325 cuts faster on a 50cc saw, nothing to do with chip removal unless your cutting something like balsa. Steve

right, smaller rim = higher torque but slower chain speed. I think we are thinking same.

is .404 better on a 066 than 3/8????
Your right, Maybe I didn't read your preivios post right, maybe something due to Christmas. Slower speed but bigger chips. Steve

Exactly, and 8-pin .325 is just a tad larger than 7-pin 3/8".....
I think the advantage of a .325 pitch is a smoother cut. Also, much less kickback. Good for brush and <2" stuff where a 3/8 might throw a stick at you.
3/8" chain cuts faster plain and simple, as long as the saw can pull the bigger cutters (pico/LP excluded).
The 325 smaller cutters and narrower kerf make more, smaller chips.
I definitely prefer the "feel" of my 3/8" 346. I like it when the saw does all the work.
The question I have is what is the difference between 325 and 3/8 lo-pro in the wood? I only have one saw with lo-pro and its in a class all its own.

That link will answer it pretty well!
Regarding lapps - they sure are around here with their raindeer, but they far from dominate the area.
