22" Stihl bar for my 461

ALL good points, Willard. Thank you for making them, for all of us to take in.

Saw protection is important, and the LAST line of defense, as you, of course know. I'm sure you have seen many a cut pair of chaps in your time working around all the people you've worked around. Hopefully not a cut leg.

What do you think is happening in the physics of your 7 pin versus 8 pin example?

What about the chip size for that raker setting? Standard is typically more, no? .025 even? Is your raker setting progressively smaller as the cutter gets smaller?

How does that type of race filing work compared to a more typical work setting (using the bulk of the cutters' lives)?

Thanks.

Please add 5 lbs and one inch...it might make a difference

As I said earlier that chain was round filed just the same as a work chain. In the more competitive contests I run square filed chain which will do better with a 8pin , but with an aggressive round filed chain you need more torque with a smaller rim.
A lot of people used to a long b/c think a 064 with a 16" with cut like crazy with the drags filed down to .040, not the case. In a race against other fast saws .015-.020 is the most you want to run for the best times with a stock or even a woods ported saw. Even in a 10"X10" spruce you have to keep your rpm up to win a close race. .025 on the depth gauges is too low, fine for work but not to win at a speed bucking race.
Work chain I progressivily lower my depth gauges from.025 when cutters are new to .040 when the cutters are filed back down to the witness marks. I use a Oregon adjustable gaugit ,or you can use a Carlton file o plate [which actually was designed to be used on a Carlton chain, but some claim it works fine on an Oregon or Stihl chain.] Longer bars over 24" I like to keep my depth gauges a little higher.

Fiona, when I was young I didn't have much height or weight, I still don't have much height.....Bill

Would welcome your thoughts on the 461 as it gets a little seasoning on it.......thanks Bill
