I hope you've got a shield for that! 
 
    I run my ASRG to 4000 rpm with a VFD. I'm more  scared of the rotary gap 
than I am of the electricity! I must've done a good  job on it, because it 
takes *10 minutes* to coast to a stop (if I don't use  the drive to brake it).

Your washers are going "against the grain". The  eddy currents are 
unfortunately not going to be terribly mitigated, either.  It'll be interesting to see 
how hot it gets.

I hope those outside terminals don't come too  close to all that pretty wood!
