Blanchard Ground in metro-NY area, of ship them somewhere?

[gsxrken]

I got too much heat into my two-piece Coleman 13" rotors running Wilwood E pads and now my brakes chatter. I'd rather not throw down a few hundred for new rotors if I can help it.
Stop-tech's website talks about blanchard grinding the rotors to clean them up versus the typical rotor turning that cuts a few thousands off.
Does anyone know who does this (preferably in NYC area, but failing that, really anywhere?)

"The only fix for extensive uneven deposits involves dismounting the discs and having them Blanchard ground - not expensive, but inconvenient at best. A newly ground disc will require the same sort of bedding in process as a new disc. The trouble with this procedure is that if the grinding does not remove all of the cementite inclusions, as the disc wears the hard cementite will stand proud of the relatively soft disc and the thermal spiral starts over again. Unfortunately, the cementite is invisible to the naked eye."

Start calling your local machine shops Ken. They will know exactly what you are talking about. I cannot help you with some one in particular in your area however.

Thomas.net is an ok source. Here is a link for New York metro area shops that have Blanchard grinding capabilities in their profile.

if they are slide on rotors with flat face have a local shop wet grind on flywheel grinder on back side with wheels mounting face side down THEN clamp it down on freshly ground rear face. If they have small enough stone tthey could even grind the inner mounting face.
With good shop all ground surfaces SHOULD be well within 0.001" or less.
