The only way I can think of to make this work is to have a separate pressure switch, that controls both compressors, bypassing the orginal switches.

No, it isn't like you're thinking. What you're missing is that if say the syatem is charged up, then you start
drawing it down first compressor A will turn on but since that isn't enough, the system will keep drawing
down until compressor B also turns on, at which point hopefully it will keep up or draw down slower.
Compressor A will run continuously in this scheme while B cycles, assuming the total CFM from A+B is
enough to keep up with a blaster which is a questionable assumption.
Ries, I'm also curious where you source your blasting material. Do you mail order it from Tip?
