Hi, I've got two new rings. This ones are occupied by a snake and a bird ... can be used as pendants instead. Michael
I wish I knew someone who owned some sandblasting equipment - I'd love to see how that would polish the metal!
Sandblasting and other media-blasting do not polish metals. They remove very small amounts of metal and leave a satin finish - coarseness dependent on media type, blasting velocity, and a few other parameters. Shotpeening will do much the same, but doesn't remove any material.
I'm thinking about to buy a sandblaster even if it's not working for polishing... just cause it's such a cool tool. Like this one... https://www.shapeways.com/forum/index.php?t=msg&&th=1 3080&goto=65137#msg_65137 Cheers! Michael
