I think I've got the book you are looking for, but it's too
large to post here: file 1.7 MB, and max allowed file size is
390K.
"Zip"-ing the file only gets it down to 1.6 MB
Any ideas?

Idea you can just email him a copy.
or email it to me and I will see what I can do to post a link.
Let me know what you decide.

Already emailed it to him, as well as to someone else who said
they'd get it on to you, Cut4Fun

Wow, I had no idea. I assumed like many that each tooth just did
a continuous cut. This explains why you don't end up with long
chips I guess. I'd love to know what process led to this design.
Was it intended, or was it a series of mistakes and trying new
things, and the dolphin effect was just what happened when it
finally worked?

I believe that each cutter rocks back into the cut and stays in
that posture until released at the end of the cut. I think of it
like the iron sticking out of the base of a woodworking plane.
If the depth gauges are too high, the cutters skip over the
wood, even if sharp. If the depth gauges are too low, the
cutters try to dig in too deep, and grab or stall.
When you are cutting across the grain (cross cutting/bucking AND
ripping/milling) the chips break into little pieces as they curl
into the gullets of the cutters.
When you are cutting with the teeth moving in the same direction
as the grain ('noodling'), you get long, continuous curls
('noodles'), just as you would planing with the grain.

I didn't feel like signing up to Scribd either so I rummaged
around and found this link to a free download of the Carlton
Chain book. Who actually has copyright? Don't Carlton want us
all to have this?
HTML http://gepkolcsonzo.eu/wp-content/uploads/2012/01/complete-book.pdf
We could also upload this to the manuals section I supose, if
it's easier to find as a reference there..
Cheers,
Gregg

Hi guys. Is the Carlton book and the book mentioned that's been
emailed around one in the same? I want to rad this but not on a
smartphone screen. My email is bleinmiller@yahoo.com if someone
would be kind enough to email it? I could have my folks print it
and mail to me then. Thank you

Bump for person asking for info in first post. Shows the
differences.

The analogy of a dolphin swimming (leaping in & out of the
waters surface), is how I picture the cutter "diving in & out of
the cut".

Bump here too :)
Yes that's how the movement was always explained to understand
the motion. But with only .025 clearance of the depth gauge it's
so small.
Which leads to another part of the innovation of sawchain in the
last 10 years...Oregon's AntiVibe or Stihl's Comfort cutter
design.
By removing that small thickness of the heel of the cutter that
contacts the bar...a shock absorber effect is made. Of course
the opposite side link on the cutter doesn't have this clearance
so the cutter can't "over rock". Only disadvantage is the
chassis could have a flex in it caused by the cutter having a
slight side movement instability. Reason old school cutters
without the clearance make the chain desirable for timbersport
competition.
Does anyone own or have information on the Stihl .404 high tooth
timbersport chain?
My question is did Stihl design it with the "Comfort" clearance
or left it out and keep it old school for better speed
performance ?
