What kind of sandblaster are you using stevec? I have a total of about one hundred gallons of air but not really that much power. I can also borrow another compressor from my brother so I will end up with about 120 gallons of air and about maybe ten horsepower. I am willing to go slow but just nothing ridiculus. How much is a lower end pressurized unit? I am just trying to do the weights and balances thing. Thanks!
