Wish to "Sandblast" Steam Locomotive 6167, What other material can be used, rather then sand?

Answer 1

Don't blame you for looking for an alternative to sand-blasting. Blasting with sand can remove metal because sand is so abrasive. Try media blasting... they have a variety of materials that will remove the paint and rust, but won't erode the metal. They can use plastic beads, ground up walnut shells, etc. that aren't hard enough to remove or distort the metal like sand will.

Answer 2

Glass beads, certain ceramic media, and then the ones listed above.

The choice of media depends on the result you are trying to achieve. Most mechanical services and machine shops prefer glass beads over sand. It removes paint and rust with less damage to the underlying metal.

Answer 3

these medias require a special blaster, corn cobs, walnut shells

Answer 4

baking soda
