Who did everyone use for clearancing their rotors?

I hear any good machine shop can do it, but I'm unsure of all of the areas that need to be recessed ~0.3-0.5mm

If someone can provide an illustration of the clearancing area, I'm sure I can get it done for a much lower cost locally.

^ Picture of a rotor clearanced by Paul Yaw... and I STILL can't tell where material was taken off!!

 

I'm pretty sure they remove material from the sides of the rotor, so that during very high rpm, if there is any e-shaft flex, the side of teh rotor won't hit the side housings.

 

so... just to be sure. They just take a couple tenths of a MM off of each side of the rotor? off of the entire side? Damn, I was way off...

 

I thinkthey leave the lands on the rotor, and take material off farther out. Also the tips can be clearenced too.

 

can anyone reccomend a good place to send these bitches to? Or if comeone could friggin get a picture of the size of a rotor, and edit in paint to show the areas of material removal...

...I can't believe I'm so dense...

 

Basically they remove material from the entire side (both sides) from the outter oil control journal right off the tips...

Mazda increased the clearance with their late model FD rotors, but they started about 1/4" from the outter oil journal. Either way would work, but it seems balancing would be easier if you started from the journal...
