Dry ice sandblasting for chassis and parts
Has anyone here ever tried this for chassis cleaning or paint stripping?
It is fascinating as it freezes the crud on contact and blows it away at 80psi or so and then evaporates leaving only the crud on the floor. It would be a sizeable $ installation for anyone to try it at home. Let's leave any safety considerations and questions for later. The cleaning would be obvious but the ability to shoot in to tube sockets is interesting. Would ink on cans survive? Would transformer paper insulation survive? There is a demo on the internet where crud on an egg is stripped and the egg is fine. All a process of pressure I presume after testing. I did pick up the Moto 7" Chinese from another thread and it is a perfect candidate for this. 62 years of dust, grease and nicotine. The bakelite is great and some Novus #2 will take care of that. I did call a local contractor to talk to them about this. Hopefully they will give me a demo. Stay tuned, Dave A
