Re: sand blasting questions
My compressor is a monster, so I have no input what the minimal size might be, but the required CFM should be listed or recommended with the blast cabinet.
The compressor absolutely needs to be 220vac, and the bigger the tank the better.
Then you'll need a good water seperator/filter/regulator.
I usually blast at around 60psi, and just a quick back and forth dusting is all your need. If you over blast, it'll come out blotchy.
As far as shaking the cabinet to get the blast media down... never had to do that. I keep the hopper pretty full.
