Let's talk race chain

[Canadian farm boy]

So you zero the angle finder from tooth to tooth, and then get the angle from tooth to raker? I think

That’s exactly what I did.

That’s exactly what I did.

Those things aren’t real accurate, not bad but I would check em with a feeler gauge

Quick video of a few test cuts. The wood is dry sticky spruce. I need some fresh poplar or something similar.

Here’s what the chips look like. View attachment 198692

Is it bad if the chips are real long, talking like over an inch or a few centimeters up your way .

Every type of wood is different and every saw and chain is different so I can’t really say for sure

If the wood is very wet, noodles typically are longer. Dry wood yields very short chip.

Someone mentioned a while ago if the rakers were to tall, the cutter takes a thinner chunk when cutting, thus a longer strip of wood.
I had a chain like that. I took 2 swipes off each raker and chips got back to normal.

I understand that.
I was just thinking as far as keeping things moving under the clutch cover.

Never heard that, but I guess it would allow the tooth to rock more?

That makes sense too(not talking noodles, although some look that way). Since most cants are slightly wet softwood I would expect longer chips.
This was a chain I did up for a 346, the first picture is in very hard seasoned cherry.
Second is in a pine log with the bark still in place but it was cut down well over a yr ago.
Thoughts/advice appreciated guys.

I have zero racing credentials, but I would be ecstatic to see those chips from one of my chains.

Long chips also indicate good chip clearance.
At least that is what I observed.

Thanks.
It was nice, just not used to being chips in softwoods I guess.
I'm not a racer either, so I was just wondering if that would slow things down.

That was on a little 346, it was moving them fine from what I could tell on the softwood.
In the hardwood I could make a 325 chain cut about the same speed, but in the softwood there was no comparison.

Okay so dog boning and chamfering that top edge reduces weight and friction. The rivets are ground down a little and I assume that is for the same.

I see the rear of the cutter is cut at an angle. And I see the inside of the cutter is ground out. Is that chip clearance? I assume along with the gullet and dog bone.

. . . I see the rear of the cutter is cut at an angle. And I see the inside of the cutter is ground out. Is that chip clearance? I assume along with the gullet and dog bone.

Thinning the cutter plate reduces resistance of the cutter as it severs the fibers and the generated chip flows underneath it - that is how I see it anyways.

I would like to have a decent way to rock a chain, but pay day is another week away.

Update, the saw and the fixture posted above was stolen from my garage not long after I posted it.

Sorry!
I can't like that post.

Any ideas who it was?
