Bar binding in cut.

Maybe today but may have to wait. Its hard to get things done these days. But I will try and make a video today to post

 

I can do a pic easy.

 

Be home in 40 mins

Amazing how busy one can be on a day off!

 

Mine did that last time out
It was to the oiler. (I think)

2 questions ?
Not sure how it works,
Does to little oil cause the Bar to get hot, expand & chain gets so tight it wouldn't turn. ?

Does a dull chain causes the chain to get hot, expand & get loose ?

Years ago I had my old Husqy 61 do that every now & then,
Was a real bad, worn out , drive sprocket.

 

My chain. Is still turning.

But bogey I think lack of oil would swell the chain so that it binds in the bar grove??

 

The first is a pic of the old stihl bar.

The next one is the new bar. U can see where I guess it got hot and burned the paint off near the tip

 

Might be a stretch but this chain you are running, was it bought from a shop that makes them up from spools? and then puts them in the boxes that the chain mfg. supplies with the chain? Could be some one mis labeled the box?

 

Got it from jim goodall supply. They have a website bit I got it off ebay. It was in a zip bag with a label I think. Not an original package. Chain was new..think forester? The other chains from there were boxed...its possible they made this one up?

I need to get calipers out and see the width on it.

The chain is as it was on the bar as I used it. If anything just a tad looser than I tighten too. But not close to jumping off or being too loose.

 

How does it cut when first in the cut , before it locks up?
Maybe a real dull chain or the rakers are to high ? (or both)

 

I see a dull chain. Time to sharpen.

 

It throws chips fine until halfway through the cut.

I agree grazer it would benefit from a sharpening but dont think thats the problem. It cuts decent half way through.

If I can I will throw it on grinder and try again. Wish mail order wasnt Bout my only option for a new chain...id like to see today what a new one would do?

 

Thats a semi chisel chain as well.

 

Look up Oregon chain dealer in your area, Try an LGX, LPX.

Has it been doing this since you put this chain on or is it a more recent development?

 

Not sure cause I almost always cut 3" stuff with this saw... bar doesnt get buried on that stuff.

 

About the sharpening thing. Best thing for you and the saw is to learn how to file a chain, ideally with guide like Granberg's.

Then touch up the cutters at every other fill-up. Continuing to cut while waiting on pulling the chain & grinding it, is way sub-optimum.

Keeping chain sharp makes life much easier on bar & engine too. Filing takes off much less metal than grinding. Much less.

Yea, that chain is not looking good.

Edit: I should add also FORGET FULL CHISEL, most especially with your weekly grinding shtick. Stick to semi-chisel.

 

Same chain on two different bars, gotta start suspecting the chain at this point. As rough as that sucker is looking, gotta think sharpening the thing is at least worth a shot. Sure looks like a dull chain to me.
