Nice work, also like the Empty.
Was thinking about doing the opposite arrangement, my stuff is usually bead blasted but wanted logos etc. Apart from etching at a loss?
Sure would be a lot of waste grit, give it time you shouldnt have any water logging issues. Plumes of fine grit lingering in the air, keep an eye out for your neighbours.
Need a blast cabinet and mod it with decent filters, used to have two guns like that p...ed me off keep refilling.
Keep up the good work.
