However, I picked up a fresh board to resaw today, and as the wood touched the blade, the blade ran "forward" (towards the wood) and climbed up onto the side of the lower wheel (the lip of the wheel), causing the blade to cut into the metal guide (ruining the blade, of course).
I have removed the blade, checked for coplanar alignment, and installed a fre$h blade. When I spin the wheel by hand in the REVERSE direction, all appears to be well. However, when I spin the wheel in the FORWARD direction, the blade seems to creep forward on_the_lower_wheel_only until it has climbed up on the lower wheel's aluminum lip.
I have no clue as to why this seems to be occurring in a single direction of rotation, and why it would begin happening "all of a sudden". There is no obvious changes to the saw, and I do de-tension (a specific count of turns) each night.
Any thoughts? Help!
