Lets say, for argument sake, that I have 2 or 3 10" blades for my table saw. That would give me just under 3/8 inches, when all mounted together, which I could use to make dadoes.
With what I have available this would be easier than constantly stopping my saw to adjust my fence to enlarge my dadoes.
I could easily see this being a bad idea since the blade kerfs could touch while the saw is operating. Also sawdust might get stuck between the blades. Has anyone tried this before?
