Ok, so I recently got the big HF blast cabinet. I know I will primarily shoot aluminum oxide. I know I want to swap out the gun for something better with a carbide nozzle.

But I'm a bit confused at how to select the gun/nozzle combo. We have a 10hp/120gal compressor, that I'm assuming puts out somewhere around 35cfm@90psi (it's old and I don't know the real specs). The HF gun comes with ceramic nozzles that are 6 and 7mm, so ~1/4in. And the HF gun supposedly consumes 15-17cfm. Charts for better guns say a 1/4" nozzle at 90psi would take 80cfm.

I want the biggest baddest mammajamma our compressor will handle. Any suggestions? Thanks a ton! -Len
