It's a little saw, but it's got a big heart ! I'm VERY impressed with it what it does for me, it whips my BIL's 51 BAD.
Has anyone else noticed that it runs better when hot, like, REALLY hot ? Seems to run like a bag of skit when cold, but when it warms up it runs WAY better. And no, it's not too lean.... although 12,000+ rpm sounds almost scary ! It 4-strokes just a tad on wot and settles down in the cut.
I tried this with my 455 using the OEM chain, wandered all over. How were you able to cut such straight planks?
These planks were done with a ripping chain, full comp chisel, but the cutters are factory filed at a 10 degree angle, almost straight. It almost doubles your cutting speed, over the OEM chain, and makes longer chips. Doesn't seem to cross-cut as well, but in the rip, it's the winner. I couldn't say which exact chain type it was, although it is an Oregon. The dealer knew what I was looking for and keeps a roll on hand.
The boards on the back wall (also in the other pic, in the bush with the saw on them) were 13 feet long, then cut to length for the shed. I have tried a few setups, but the best one is having the log horizontally mounted on blocks of wood about 1 foot above the ground, wedged in snug so they don't roll. That puts the saw at the right height for me to hold it comfortably, while keeping my eyes in line with the bar, as well as the beginning of the cut. I also noodle the beginning of the log for each cut, giving me 16" of straight line to start with, to have a good starting point.
I think the trick is to keep the bar and the start of the cut as equal as possible, thereby making even, straight planks, with a minimum of waste. I can get 5 planks now from a tree about 12" in diameter, 6 or more from a 14 incher. However, if you screw one up you waste material for another plank.
Go to your dealer and have him make you a loop of ripping chain. If he knows anything about saws, he'll know what to give you.
