Yea, that's what I was afraid of. I did check all the specs. The harbor freight 40 lb pressure pot says something like minimun 6 cfm @ 60psi. My compressor should be about that...but I generally don't like to be at the minimum-seems like a setup for disappointment. The cabinet itself doesn't really say much except to set at 100psi and it will be 10cfm which is definitely too much for my compressor. So...maybe I will just do it the old fashioned way but then save bigger parts if I can ever figure out when I can get over to your place...and once again....really appreciate the offer Steve.
