    First task after recording all the stock numbers is to cut the squish band. I took .055'' off of this one. Also have to cut the base down so that I can get the squish set where I want it.






    Another thing I'm doin to this one is lightening the flywheel. Was only able to shave 13 gr. of of it. I could have taken more off of the fins, but this saw lives down south & didn't want any issues with cooling.

    Hi Stumpy
    By the looks of the flywheel holder you have found some use for the remains from the old shop.
    Hope you find use for some of the rest of it.
    Hows the new coop progressing?
    Thanks for posting pic's for use to drool over
    Thomas

    That saw has already lost a good bit of its punch. New, it will be 20-25psi higher.

    Hey hold on a minute now, regarding that pic with the Stihl, that's no ordinary Stihl. That's "Christine", and she has quite the attitude. spike60
