Ok I don't have a flat on the arbor so I'm stuck with one wrench and a piece of wood wedged in to get the blade off. I also tried a Quick Clamp on the blade and that works well also.
My problem is tightening a new blade on. The wedge doesn't work in the opposite direction, but the Quick Clamp does. That eliminates blades loosening when the saw is turned off and starts to spin down.
So...what is my problem? Stacked dado heads. If not tight enough, power off the saw any I get a bunch of expensive carbide clacking together. The clamp squeezes them, the wedges slip. Other than grinding a flat on the arbor ... any ideas?
TIA
