I have an older Sears 10" table saw (1940s-50s) (113.27520). What size
stacked dado blade is safest to use with this saw - 6", 7" or 8"? This is
driven by a 1-1/2 HP motor.

All three sizes will remove fingers with ease; none are "safe". I have
always used an 8 inch dado because it can make a deeper cut.
