Upcut versus Downcut Times?

[Crofter]

Does anyone have a breakdown on the times of the upcut in relation to the downcut in actual competition on the same piece of wood.

Hi Frank, although I am no expert other than by my own admission, it depends on the operator. Since a pulling chain, or down cut sucks the saw in to wood, and a pushing chain, or upcut pushes the operator back, it all depends on technique, stance and style. I for one like the upcut, since I can be pushed easilier than pulled, plus I groove on the resultant rooster tail, but I have to thank Ken Dunn for getting me involved in the first place, but then again, I always was a one hit wonder, and why wouldn't I be?

Is that why you're not married?

Ya gotta worry about someone who grooves on rooster tail.

 

[Gypo Logger]

I figured that would bring you woodticks out of the closet.

Since most of us can probably pull a chainsaw into the upcut hard enough to stall the saw (well, except for really big saws and small sticks), doesn't it stand to reason that times should be similar?

I'm with Gypsy John on this one...especially if you can line up to fill your buddy's windshield full of chips with the rooster tail...Heh, heh.

There is lost power in theup cut because the distance from the drive sprocket to the wood is greater and the chain has to roll over the tip under tension.

That make sense Mike, But has that been proven or not?
It seems to me that with a roller nose it would not be much of a factor. Also the oil goes too the top of the bar first so it seems that would be a advantage on the upcut. Unless some competition bars have a oil channel cut to the lower roller
end of the bar. It would be neat if someone with too much time
on their hands could prove it with some timed cuts. Or maybe they allready have.

Hey Onthehillintn, you're pretty smart, that oil thing makes sense.
Because I don't know the answer to the original question (or your's), I'll add this: the saw shavings get sucked into the sprocket area on the downcut, which will slow things down too. In the upcut, they shoot out and hit your friends in the face (hopefully).

 

[TheTreeSpyder]

Both of them?

Oh, for crapsakes it's the down cut. Of course that also depends on what chain lube your using. Nuff said.
