So, finally found time to put this to use. The size is incredibly convenient and doesn't tax my 30 gallon compressor too much. I used glass beads and blasted some small metal parts that had rust and welding scale. It cleaned them up nicely and allowed for quick and even polishing once done. The box is pretty tight and there is minimal leakage. I had read that the nozzle was placed to where the media would blast upward towards the glass so I simply unscrewed the nozzle from the back, taped over the screw holes, and used the nozzle as a hand-held gun. This gave me more room to work and allowed me to aim into tight spots much easier. Overall, this is a nice little sandblaster and will suit most of what I need. It stores away easily as I don't have a lot of benchtop space to dedicate to it. Very pleased!
