Aside from the depth of cut are there advantages to a larger bleade?
given the same arbor speed the teeth would hit the wood somewhat
faster, how much I don't know, enough to matter I don't know.

I need to buy a dado set for my table saw and my saw has a 1"arbor. I
want to find a used set to save a few bucks. most of the ones I see
are 10" or 12" sets. My saw has a three horse motor. dose anyone see
a problem with buying a large dado set?

Thanks russ
