Not to be a jerk at all here, but I seem to live without a dado cutter just fine. Maybe I am missing something, but it always seemed to me to be faster to make my dado's with my radial arm saw or tablesaw by making several cuts with the regular blade installed. I then clean up the bottoms with a shoulder plane and I'm done.
As I said I am not trying to trump your idea Jeff in any way, it just seems like everyone uses these blades but me. Am I missing something? It just seems to take too much time to change blades back and forth all the time when you can get by with multiple passes with a regular blade and finish up with a chisel or shoulder plane.
Maybe its the dado stack I got. Its a cheap set and I always seem to get rippled bottoms on my dado's.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
