Greetings fellow nerds.
I am troubleshooting an issue with my sandblaster and was hoping for an advice here.
Currently I have a very underpowered compressor, 2.2SCFM at 90 PSI. i know...
Anyhow, i was looking at reducing the flow rate by using small opening on the blaster 5/32nds vs 6mm that came stock. The problem that i am having now is that i have air blowing out of the pick-up tube because my 1/4 inch supply line basically provides more air than can escape through the nozzle opening. While getting a bigger compressor is the long term solution, i am trying to understand what variables i can change to get a small spray pattern at 90 psi and low flow rate? Do I have to reduce the hose size from the regulator to reduce the supply volume to match the smaller nozzle? I'd hate to do that to avoid psi drop in the hose and additional power loss. Do i need to put flow rate choke, basically a 1/8th " tube right next to the nozzle air inlet?
