How the sandcast really turned out

Here's the picture of the finished item. The reason it has taken so long to post it up is that the cold working is really slow and laborious. To get the copper figure to show (hope you can see it at this size), you have to grind it on the flatbed wheel, then hand grind 3 times on 4 different carborundum powders - starting at 180 and ending with the finest at 500. Then, you smooth it further on the cork linisher (about 4 times) and finally on the pumice wheel (also 3-4 times). Finally, it goes shiny and see-through. If I'd known, I'd have designed it better. I'm still quite pleased with it.
