What's the minimum setup that i can get away with to do sanblasting? I read all the threads that I could find and it sounds like I won't win any speed records but I can get away with a single stage compressor. I have one now, but it only puts out like 6.5cfm at 90psi. I typically avoid HF tools unless they are throw away items, but this might be a case where I can use them coupons...?

I have seen nice sand blasts with smaller units than yours, it just takes more time waiting on the compressor to catch up. I am using a HF 60 gallon unit and an HF cabinet. My blasts are OK. I think that I am getting about 16CF per minute at 80 #, but am using a 1/2 “ line about 20 ft from the compressor.
I could get a higher pressure with a shorter, larger diameter line.
Both the compressor and cabinet were given to me by my brother.

There's no way to get around this you need an 80gallon 5 or more hp that can deliver 22cfm at 90psi.that's the min.I Know people do it on a lot less but are they satisfied??Many are on a budget I get that too But to save money and spend it on enough to get by or just wait a bit longer and save the money to get something with
No regrets plus when you need more because you're frustrated that the stuff you have doesn't get you to the next level you got to save all that money again After being half a lifetime in the trades I have learned NEVER have tool regret :takethat:
