How many of y'all have undersized plywood bits?
I have always cut dados for plywood with my dado blade and my table saw.
I have a project which involves cutting dados and rabbets in several long pieces of somewhat wide plywood.
Not something I would care to do on my table saw.
Therefore I can cut the dados w/ a 3/4" router bit and have a little "slop" - or I can buy an undersized plywood bit (or set).
