I agree with Mike, I spent $500.00 on a 60 gallon, 220v, twin cylinder, 7
hp upright Craftsman compressor with sandblasting in mind but it doesn't
push nearly enough air to do good blasting. After internet research I found
that most proffessional blasting suppliers recommend a minimum 26-28 cfm for
a real sandblaster ( not a little siphon toy like I bought). My compressor
is only capable of pushing 9.9 cfm @ 90psi and you don't get good results
till your up around 120 psi anyway's. It's a good setup for a cabinet
blaster and I love it when I'm using my orbital sander or jitterbug but for
real sandblasting work it doesn't cut it. By the way I've heard bad things
about using silica sand ( beach sand), good way to get silicosis. They say
that commercial crushed glass doesn't contain the same silicates and is
safer and has better abrasive quality's although it's more expensive.
