Dad gave me quite a few of his tools included were a Craftsman 8” HSS stacked dado & 3 carbide toothed wobble Dados one Rockwell & 2 Craftsman all 40 years old or older. The Rockwell is a 6” & not big enough for my saw the 2 Craftsman are about 7”. I tried the one with the most teeth & surprise it works great nice flat bottom & clean square edges.
