I have been wrestling with this arbor all morning and I can't get it free. The blade that came with my SS is rusted pretty badly and I have a shiny new Irwin ready to go, but I can't get the arbor loose. My gut tells me it's reverse thread but I have tried both directions...nothing.
I have soaked it with WD-40 for the last few days and let it sit. It doesn't seem to have helped at all. I think I have plenty of leverage but no go...see my set up.

Any suggestions much appreciated. I may be looking at a new arbor

Peace,
