Chain problems

[Travis_32]

Alright so my saw cuts like an absolute best when it’s laying on its dogs pulling in the wood but when I try to cut with the end of the bar it doesn’t want to cut and I know it’s sharp and I file the depth gauges so why does the end of the bar like crap

There is only one explanation i can think of. And you wont like it[emoji23].

The chain is either not sharp or not sharpened correctly.

Probably not dull, but have safety chain on it, put up a pic of your chain from the side view.

Same cutters at both ends of the bar. Traveling around, maybe 20 times per second. . . .

Saw motor runs the same, right?

When cutting with your dogs, are you using them like a fulcrum/ pivot?

Not to be a smarta**, but how does the chain cut in the middle of the bar?

Clear, close up photos might help.

Bar rail worn, or sprocket tip worn, thus cutters laying over and not taking a good bite ?

and...and...keep going.

what are we miricale workers?

what saw? what chain? how much chain has been filed? Species: hard? soft? dry?
free hand rakers or saddle gauge or progressive gauge? what size file? file
gauge?

Could be backsloping as well loosing rakers depth due to wearing chain.

Just answer the questions and post a few pic's of some woman or manikins in lingerie. Headless ? Just as well.

Best guess so far, seen this many times. Picts of the saw chain at the bar tip needed to make any educated guesses.

Dull

Probably not what you want to hear.

Remove the dogs, install a new out of the box yellow / non-safety chain and retest. Guessing the variation will decrease dramatically. Having been to many GTG in the past, the number of people observed that think slamming the dogs into the log and lifting with their legs is proper sawing technique is alarming. Also explains why so many people think they need a 90cc saw.

As previously stated saw, bar length, chain mfg and type, and a pic of the chain would all be useful data.

Not discussed, but another factor to look at is the chain tension. Either too loose, or too tight can cause issues pulling a chip in the kerf.

Take Care

Or the metric equivalent.

PICTS!!!

Chain not as sharp as you think it is.

when it’s laying on its dogs pulling in the wood

Well, those words are not clear in their meaning at all, but I believe it is probably a clue as to what is going on.

IF you are using the dogs to leverage the bar down into the wood, forcing it to cut, then you are simply mistreating your equipment by jamming a dull chain and/or worn bar into the wood and then wondering why is won't cut on its own when you cannot force it.

 

[HarleyT]

It is obvious, his chain is on backwards!!!

 

[HarleyT]

He is not using synthetic oil!!

Well we have certainly seen that before

Safety chain only affects how it cuts on the very tip of the bar, around the sprocket. I.e. a bore cut. Even then it'll still do it if the chain is sharp, just slower than non safety chain.

It’s a low kick back chain

PICS!!!

Not sure if it's the picture quality, but the tooth on the right looks awful.
