    Do the math. Take sprocket daimeter X RPM = speed (velocity)

    Convert that to the units of your choice.

    Bar length has no meaning/function in the chain speed unless the saw is a dawg that can't spin it

    Stihl:

    FS 66 (projects)
    BR 400
    020T
    026 s 1 runner, the other waiting for P/C kit
    028 super (rebuilt with OEM)
    036 pros (1 runner, 1 just rebuilt with OEM parts)
    038 supers (2 converted to 038M , the other waiting it's turn)
    038 magnum II
    056s (4, two spares for the mill (magnum) , 2 parts saws, not for sale)
    066 magnum (mostly for the mill)

    I cut it down and my partner and I made about 5 to 6 cuts to make it easier to handle. Quick and easy money.
    It's always fun to follow up somebody who hasn't got a clue.

    Cut one a while back for a friend that got in over his head.... little cut here little cut there..... little cuts everywhere ..... why didn't it fall???

    I've got a neighbor that leaves some nasty looking stumps... looks like a blind guy whittled at'em with a spoon.


    How close were you cutting??? should've given me a call just for the entertainment.
    .

    Darwinism..... thinning the herd for over a million years.
    Just because you can't do it doesn't mean it can't be done.

    In need of a Dolmar 166 muffler... shoot me a PM if you can help.

    Thanks to all for the imput

    Thanks to all for the imput...I just needed to have a general idea so I could impress my Grandsons as to the speed of that chain ..probably 0 to 80 MPH in 1 sec. That should be a reasonable statement and should make them think a little.. I did not want to lose creditablity with them and need something they can sink thier teeth into....and 80 MPH should make them take notice!
