I would prefer powered off/normal on, because the operator would get
used to the blade always braking and in the case of a solenoid
failure, the blade would not coast.

I would also think an assembly with wheels applying just a little
pressure to the sides of the blade would make a decent passive
system. It would be just enough pressure to slow down the blade in
a second or two and not enough pressure for the motor to even
register the resistance.
Think about how little pressure it takes with a scrap piece of wood
to stop a coasting blade.

Isn't there an old Indian trick about a spinning piece of wood and
starting a fire?


Point?

Everybody knows that, which is why I'm trying to explain. But everyone's
alive except those who drowned in an adjacent bog.
