My biggest issue is that my arbor is too short (a common complaint among middle aged males). My old Craftsman contractor saw is a hassle to mount even one additional blade on. The blades slip down onto the threads and end up slightly out of alignment.

I stack my dados on the bench and clamp them together, then slip the stack on the arbor and tighten down the nut, then release the clamps. It works most of the time. I wish I could find a sleeve to cover the threads and allow me to slide on individual blades, but I feel like the wall thickness would just be way too thin. 

Anyone have any ideas?
