Thought some people may be interested in this.
As an exercise I ordered a brass lost wax casting from Shapeways. The part is the water scoop operating cock for the tender on the Aspinall class 27. Don Young just says fabricate from brass. So I though I would try a cast one from Shapeways as an exercise. The CAD model was scaled by 3% to allow for shrinkage. Anyway 10 days and 16 euros later the part in the photos turned up. As you can see the part is not very big and the photos show a bit of faceting, but at normal viewing distances the finish is not bad.

For small details parts I may use it again
