Hi Paul...

I have been following discussions and feel their maybe a way to improve the
cleaning of the used rotors.

I worked on this process during the GM remanufacturing process of alu blocks
and cast iron heads.  The original process used glass beads.  Quality control
did main bearing checks to determine the glass contamination level during the
assembly process.  The work in process received two hot water washes before
final assembly in two different machines.  The truth of the mater is that
glass beads break down and leave residue inside passages and is very, very,
very hard to get rid of.

We changed the process to use a slinger process where veins rotated on a
shaft and slung the media against the block which rotated also.  The media
was a stainless steel with the ends cut at 45 deg angles.  The length was
.100 as I remember and left no glass contamination.

The removal of the oil was a baking process, 450 deg for 12 hrs with a fan to
stir the oven air.

I think this process may be available in small numbers if anyone is
interested, I will get a price quotation.
