engine and drivetrain just a note about using abrasive grit blast cabinet

[jerry]

i was reading a post below cautioning against using grit blasting on engine components. as an aside, where i work, we use aluminum oxide and No.13 glass beads and plastic media to clean and remove paint, carbon buildup, corrosion and oxidation on all types of aeroengine parts. these components are made from all types of material such as Nickel-based alloys, aluminum, and magnesium.

additionally, the paint shop will use their own No.13 glass bead cabinet to prep cleaned parts prior to painting, handling only with cotton gloves after the prep.

i only allow cleaning department to use up to 40psi pressure when working on my repair instructions. hasn't been a problem except when folks get sloppy blowing grit out.

btw, for a case of Red Bull, i've been known to avail myself of the cleaning department for my own needs. almost like getting NOS parts.

the 'issue' I have, and thread below is -

NOT where parts are lubricated or related to engine/driveline internals .

Cleaning external parts is fine.
