After reading the forums here, I figured I'd have trouble finding a 1/16" slot cutting bit locally, but I really wanted to have it for this weekend (short of paying $30 for overnight shipping), so I began the hunt. First place I stopped had a 1/16" bit but no arbor. I tried three other places, no arbor. I haven't tried Lowes or Home Depot (maybe Menard's?) on the other side of town yet.
Is the arbor specific to this bit and to routers or is there something else I should be able to find and make work?
