David,

How close do you hold the nozzle from the media? You might want to try 6" and back off on the pressure.

David,
I tried blasting these with 33psi as recommended by Photobrasive. When I turned the pressure down to 27psi, I got a much nicer etch.....

Probably nothing but the standard inaccuracy of the pressure gage. Minor wear in the nozzle or venturi mixing area can make large differences also.
