For those of you doing your own engine overhauls I finally found
a source for walnut shells for my Harbor Frieght blaster cabinet. 
I have given up cleaning rotors with chemicals. Smelly, messy 
and they don't work anymore thanks to the EPA.

Walnut shells break down under hot oil and pressure and they 
are less likely to damage the engine in the event some are 
left in there. Can't be said for most other blasting abrasives.

The companies name is Agra Shell 4560 East 26th Street in LA
Phone (323) 261 8128

Unfortunately the minimum is 500 pounds. They don't ship UPS
or deliver. So I need to go down and pick it up. It comes in 
different sizes. The recommended size is 1/3 your nozzle 
diameter. McMaster-Carr gets at least $26.67 per fifty pound
bag plus shipping. I can save about half if I buy 500 pounds.
