what causes these marks on a round?

[blacktail]

I just pulled this alder off the rack and noticed the odd marks at the end. What gives?

I have some wood like that, it was where it was cut with the feller buncher.

 

[Gark]

Maybe a side-ways bent cutter tooth on the chain. What's a feller buncher?

 

[flyingcow]

I think it looks like marks from a feller buncher too.

Maby a lose chain and that wood looks green

 

[iceman]

That's alien markings....
Commonly found in Canada.. looks like they are moving south


I agree it a buncher

Bent tooth/raker, worn bar, or you may have pinched your bar in that cut. Def not a feller buncher.

Could those marks come from the splitter?

 

[bogydave]

Looks to me like you are forcing the saw hard into the wood every inch or so of the cut, only using 6" of the tip of the bar & may have not sharpened the chain evenly.
Get the saw face up against the wood & let it do the work.
Your arms will thank you, less vibration transmitted to you hands & arms & less effort

+1
A feller buncher would leave arc shape lines and a rougher cut.

This was from a load that I cut with my dad. After seeing his chain, I'm going to guess this was a piece he cut.
And it's not fully seasoned. This is alder that was down a long time but only cut and split a few weeks ago. I only brought a couple of chunks in and stood them up in front of the insert.

+1. I notice that from time to time when my chains are near the end of their sharpening lifespan. The tooth is easily bent when it is worn out, and makes that kind of pattern......

Yep those are saw chain marks from your saw! A feller buncher cuts and shatters the ends and they look kind of ragged and exploded like.

Are all the rounds like that? Just wondering alder is almost the same as ash when it comes to building stuff. (Like guitars)

 

[blacktail]

I only saw a few rounds in the stack that look that way. Most of that wood is stuff I cut but some was cut by my dad. He ran into some problems with his chain on that trip so it makes sense that it's marks from his saw. It's was an old chain to start with.

Darn crop circle people are now marking up our firewood . . .

 

[nate379]

I think I burned all the wood that was cut with a feller buncher or I'd take a picture. To me it looked like that, though I am on a ~3" screen as well so the picture isn't easy to see.

that's the tell tale end result of a "pinched" chainsaw !
