Could one of these run a sand blaster for doing frames
and other heavy items - outside?
EXACTLY my use.
TIP ceramic nozzles START at about 1/8" orifice - but quickly and then more slowly wear out to about 1/4" - and at 1/4" the GS runs maybe half the time.
I.e. indicating some margin still left - but time to start thinking about starting over.
I use a fairly "fine" grit. I have used "beach sand" on occasion simply because it was cheap for me then - and living on Cape Cod as I was I was virtually surrounded by the stuff - it simplified clean up if done in the back corner of my property.
I have tried Black-Beauty left over from the boiler cleaning at the power plant. They use big nozzles and work fast and their NEW BB is not good at the 1/8" hole - although not surprisingly, USED BB is better. The power plant had TONS of used available for the taking.
Here in Cow Hampshire, the major source of Black Beauty was just south of Merrimack Station off Route 93 - which USED to be the source for the Coal slag. They're still around but not likely at that location.

My GS compressor was best between 75 and 100 psi. The lower number would be "better" not only in the ability of the compressor to keep it, but also in not "pulverizing" the grit to dust. When one does body panels, too much pressure can "warp" a panel.
"Impact stress relief" would be the engineering term - you short term "compress" the metal and the "rebound" relative to the surround relieves the stress - and allows the panel to warp.
