> Hello;

 Has anyone here done rotor clearancing for an aircraft application?
 I assume this is typically done with a grinding/polishing machine, has
 anyone done using another method?

 Also
 Paul, are you using the stock oil pump and pressure regulator in your
 PPort?

 Cheers
 Cary

Yes on the rotor  clearancing but I think it is unnecessary. We never run over
7500 RPM

I don't know yet. I left that decision up to John at Mazdatrix. Perry Mick
has been flying one of his engines for a couple of years now.
BTW engine parts are at the balancing shop as we speak. If we are lucky
we will have it running before Sun & Fun.

at the tip and taper it off to zero where the bluing is.
   Rob Golden at Pineapple racing told me to do this and considered it
absolutely necessary.
