I have a Delta table saw (5/8" arbor) and I bought the 8" dado set. The saw and dado blades work fine, until I go to take the dado blade out. The last time it took me about 15 minutes of walking the blade from side to side to get it off the arbor. It would only move a little bit with each wobble from side to side. My regular saw blades from various vendors do not do this, so I am sure the dado blade is the culprit. To fix this I thought of mounting (cole jaws) the two outside blades to a jig on my lathe and then trying to sand the blade hole a bit to give me a little room on that saw arbor. Is this a good idea or bad and am I missing a more simple solution to this.

Thanks
