How to separate magnet from shaft?

[littlegiant]

Oh and by the way i just had to say this. Kb45 owners shouldn't be worrying about the rotor magnet debonding from the shaft at all. The damn magnet just could not be seperated from the shaft no matter what I tried.

my rotor seperated from the shaft in my KB45-8xl. now, i'm debating whether or not i should try grinding the shaft to 5mm on my KB45-12l.

Oh man, I am so jealous of you. How did you seperate your rotor magnet from the shaft? I've been trying to do that. I want a new rotor shaft. I think you got lucky. Did you overheat your kb45? Do the KB XL rotor magnets come in a single piece?

:D

We separate the shafts from the magnets by putting the rotors in one of our ovens at extremely high heat.

This heats the epoxy until the shaft can be pulled out.

Yes. That's why we separate them.

Then we can re-magnatize the magnets.

OoooH I guessed that part right.

Anyway how do you magnetise a demagnetised magnet?
