I have been a lurker for a long while and got some good info. I don't have a digital camera, big reason is most of the ones they sell are for hands of a baby and 35 mm cameras are a bit pricey.
Anyways an observation and a bit of wisdom. I logged back in the 70's and ran chainsaw mills back then. Some of us remember the days of chainsaws with NO anti vibe, big heavy units, the 090's weren't the only animals out there. When I think about it my hands and arms shudder at goin back to something without anti vibe. Heavy, get out of town, you know you were in for a workout.
Well I built a bunch of race cars and bikes. Loved Harleys but... you were not gonna beat a Jap bike. Drag racers figured it out so did Nascar. My friends Horsepower is King, Torque has become only a player. If you can build HI RPM Horspower you is gonna be the winner.
I am sure that some player could take an 090 and get a few more Rrr's out of it, but is it worth it.
Two stroke technology is amazing. I have a friend that does Motocross, runs 125cc Kawi's, water cooled and they are gettin over 45 Horsepower out of them, they ain't that heavy. If I remember some of the figures, (its been awhile) they were a lot lighter than them 090's even with the water cooling.
These days, I am not brand loyal, Stihl and Husky are both good saws. I run a 3120. I read someplace that someone was cutting black walnut, with a 3120 and a 12 Foot bar on it. Single motor, not a tandem unit. Years ago we never really had any luck running two motors, getting them in sync was trouble, the other issue is the same for many of us, we mill alone a lot of the time. Friends would always want to help out, its somethin new, but rare was the time they showed up to help again. Work is still a 4 letter word and millin is hard.
We used to file by hand, but that got lame, the new grinders are the way to go.
Technology has been a blessing, the new saws are the way to go. Chain technology has improved with better materials. Gas hasn't.
Personally if I entertained the idea of goin back to an old saw or usin twins, I would make a mill and use a watercooled Kawi motor. Not gonna happen.
I have several bar setups, one using the auxilliary handle, has a nice roller bearing. I like the Cannon bars, they have more meat in them from top to bottom, a lot less flex. (Not thicker but there is more bar accross the flat). I use the auxilliary oiler with the big bars, but I do different with oil. I use winter bar oil in the can and regular bar oil in the saw. I have checked the heat of the bar and even tried usin good motor oil on the bar, with good success. Chains stayed lubed and easier to clean. Using motor oil, the bar was a lot cooler.
It is somethin you would have to try for yourself.
I hope this helps someone out. For what its worth, I'll have a softspot for the old 090's but the new stuff is really the way to go.
Happy millin
