Sandblasting

[Jeff Gordon]

In desperation I bought myself a large petrol powered high pressure washer with sand injection at 1300 PSI. Works a treat and no dust. If you do it in an area where the sand can dry its even recyclable.
Don't forget you need to treat the resultant bare metal straight away with phosphoric acid or similar.

Graeme what sand do you use? I have been using medium river sand after I have sieved it, however I am still concerned about the silica dust after the water has evaporated. Apart from that it is so fast and does not heat the metal.
