My question is, if I got the aforementioned cabinet, and got a compressor that is rated at 4.2 CFM @ 90 PSI, how will this effect the blasting operation? I will be blasting mostly small parts, so I was also looking into pencil blasting cabinets that only require 1.5+- CFM at low PSI. Should I consider pencil blasting cabinets as solution? Thank you.

As a rule of thumb, the bigger compressor that you buy the higher the volume of air which is what you need to do effective media blasting. You may also consider that at sometime in the future that you may want to use air operated tools on your compressor. Now consider that you have your pencil blaster and now want to start blasting mainfolds or vehicle suspension parts. It will work! BUT because of the low volume of air you will have to continuly wait for the compressor to build up pressure in order to effective blast those parts.
