As routercnc says, the construction looks a bit flimsy for a good finish on metal but I cannot speak from experience of this type of work.You could use the Trend machine to make a master out of acrylic which you then use as a stamp for moulds. A machined acrylic surface can be given a shiny finish by carefully playing a gas torch over the surface. Alternatively use the machine to cut a mould in pre-made blocks of plaster of Paris. This process is rather messy though and will need a dust extractor, but can be used for making moulds for casting molten silver if that's a route you want to try.
