Dad had a little portable blaster from Craftsman, amounted to a 5 gallon bucket with a sloped bottom and a copper tube exit out the bottom and a gun with a ceramic nozzle. I know the compressor was 220v single phase but don't remember the hp probably 2 or 3. I made pocket money sand blasting projects for friends with that little gun. It was good that the contractor dad worked for had multiple pallets of silica sand in the yard at work :lol:. I had a trough to put the work in and also recycled the sand.
