Got a question fellas. I have been running a 24 inch cheap forester bar on my 385. I use that saw for bigger stuff. However, sometimes when working up logs, the bar is long enough to stick out of the cut. My question is this. Why does the bar flop and vibrate so bad? Is it the brand of bar? I bought it due to the cost but, would have no problem upgrading if the bar is the cause. I had this problem on a 394 and 395 10 years ago when I went to a 30 inch bar. I don't remember the factory 24 inch bars doing so. But, on the longer bats, it caused a lot of chain jumps on those saws. So, I just went back to the 24 inch bars. The last thing I want is my chain jumping. It hasn't been an issue yet on this saw. I just wandered if I need to address it before it becomes one. It, is my memory fooling me? God bless men
A certain amount of vibration is normal on longer bars. If the chain is jumping maybe you have it to loose. I do not think that just because it is a Forester bar that it has an excessive amount of vibration. Like Nixon said how aggressive are the rakers set.
They are stock. Haven't filed them at all yet. Oregon chain. The wood is dirty. It has been skidded. The chain has been sharpened a couple times. But, it does that with chains right out of the box too. Like I said, chain jumping hasn't been an issue with this saw. And most times the bar is buried. I just notice the bar vibrating back and forth when it's not buried. Thanks for the replies. God Bless men
Well a certain amount of that is normal. If I have a long bar with the end stick out even an Oregon bar there is still a certain amount of vibration. No worrys.
Bar vibration is normal like you see. It gets worse with chain that is not all perfectly even filed as rakers
I knew it was to be expected. Just couldn't remember it being any worse on the saws that experienced a lot of chain jumping, than what it is on this saw right now. Thanks again men and God Bless
Now if you wanted to see a bar dance in a cut, you should have seen the Homie 150 I was given (to resurrect) a few months back. Its chain looked like it had been used for cutting flagstones, so it took a few go-rounds with a file to get ALL parts of the cutters in shape. The punch-line: while the sides of the cutters were still not in prime shape, it really danced & bucked in a cut. No mo o'dat. I'd see to it that all faces of the cutters are properly sharp. As needed, it may take a few go-rounds. No need to file it all off instantly.
Yank, I got the time and light to really touch the chain up well. The chain needed it. It is pulling very good. While I haven't got to cut in anything smaller, exposing the bar, since doing so, it feels better. At least until it hits something to dull it again. And it will. Sooner rather than later. :^) God Bless men
