Burgie, I had a Sears Compressor that was very similar to yours. I found it a painstaking process trying to cabinet blast while waiting for the compressor to keep up.
I bought an Ingersoll Rand 5 HP, 2 Stage , with an upright 60 gallon tank. Under constant use with a medium tip in the nozzle, the new compressor will catch up and shut off ..
There are a couple of pictures of my set up on my web page, click on the link below..
