  • 3650 90 blade

    I am having trouble getting my blade to a true 90 degrees. I am afraid to crank too hard on the trunnion as I have heard of people snapping it. I have cleared out the saw dust but it is still 89.4 degrees with a digital angle reader as well as not quite 90 with a square on the table.

    Any ideas?

    Could it be that the 90 degree stop is not adjusted properly ? Look for it and try to adjust it to allow the blade to move into a perfect 90 degrees.

      Back off the travel stops and be sure the contact areas are clean. Then see if you can bring the blade to 90 with the table. I take it you have zeroed the gauge with the table top.

Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."

        If you haven't already, try taking your measurements with a different blade. It's possible that the blade could be slightly warped.

          I agree. I often have to clean mine as sawdust gets packed in there and acts like a shim.

            I have had this as well. I cleaned all the dust out, and I mean ALL the dust. Use some WD40 to lube up the gears, etc, and the check for square. The truest test is a test cut, in my opinion. So get everything square, and take some cuts. If your blade is old or worn, this is the time to replace it before your commit an hour to tuning up the saw.
