    I am ripping a piece of ash with a quite new Thos. Flinn saw. No matter how straight I think I am at the beginning, the saw curves to the left within the cut with frustraiting regularity. I have attached a picture to demonstrate what I mean.
    Can someone suggest why this this happens and how to correct it?
    Thanks

    Hi Keith, I’m new to all of this and never responded to any forums, just lurking mainly…. But in my limited experience the amount of set on the saw will cause tracking issues. You may need to check to make sure the teeth are set equally to either side of the plate. Since you say it is a new saw this could be a manufacturing defect, or it could be your grip as well. I have found that loosening my grip has helped tracking, and when added grip is needed, I usually only grip with my index and middle fingers. Or if you are gripping your saw with your index finger outside of the handle (pointing along the plate), only grip with your middle and ring fingers.

    I had this exact same thing happen to me on a new rip saw and like onjki suggested it came down to one side of the saw having a hair more set than the other.

    I posted here and left some resources on the thread and received some excellent help. Here’s my thread on this:

    Many thanks to both of you. Lots of useful information that I can apply. I changed the set very slightly and voila! A straight cut.
    All I need now is practice more.

    I always had the problem of the saw veering to the right (I’m right-handed). Stoning the set wasn’t working and I thought that I was holding the saw lightly. Turns out I had a death grip with my little finger while the others were quite well behaved. A conscious effort to not grip tightly with the little finger has resulted in dead straight sawing. Sometimes it’s the little things that get you.
