Thanks for starting this topic. My setup is very basic,my blaster is one of those cheap 50lb pressure pots (red ,about $100). For air i link two compressors together,one puts out 7 cfm with a 15 gal tank and the other puts out maybe 12 cfm with a 30 gal tank. This is still on the lower side of air needed for doing larger work like mower decks or panels. When im doing those i mostly spot blast the bad spots and leave the good. The compressors do get hot and run alot so i place a box fan right on them to help cool. As for the media i have been using straight sand from the home depot that i screen first to remove any small rocks or junk, I know this is not healthy and " i will start wearing a mask Rhonda i promise"
but i try to do my blasting on a windy day and stand up wind for many reasons. The sand just gets lost in the grass. Hope this helps someone as it took me a while to figure out this setup that works for me. Dave
