You have more than enough pressure & more importantly, volume to run a small
blast cabinet. I've run a 6.5 HP / 60 gallon rated at 9.4 SCFM for years on a
small blast cabinet. I finally stepped up & added a second 60 gallon air
receiver, and piped my entire shop with 3/4 galvanized pipe. Now my
compressor runs alot less. So I'd say that the increased volume really
stopped my compressor from running all the time. Oh yea, John Blair has my
old bench top blast cabinet, and I'm glad to see he is still using it!

John,
For starters compressors are a lot like computer
memory, disk size, and money;
you never have enough.
That said, I run a blast
cabinet and a pressure blaster (not at the same time)
with my craftsman 30
gal, 5 hp 110psi compressor. I can blow more air than my
compressor can make,
so every 5 to 15 minuites I have to take a break and let
the compressor catch
up.
But one thing no one has mentioned, is the size of the nozzle. For a
hobbiest,
use the smallest (dia.) you can get. Then as it wears, and opens,
you will use
more and more air. You blasting will get slower and slower.
