My signet ring arrived yesterday! The metal print was actually a lot more detailed than the WSF I ordered first (the top and bottom fused for that print!) The only foreseeable issue would be the tiny amount of rust that's accumulated in the hard to access nooks and crannies from the past day or so.

Has anyone tried using a rock tumbler on SS? I want to shine it up a bit more, but nothing excessive.

That looks pretty neat!

I've not got a rock tumbler, so can't comment on it's useability for polishing stainless... I use a generic Dremel type tool with a variety of wire wheels and sanding drums along with some Brasso and felt buffing wheels to polish/buff up my stainless models. If you need any pointers, feel free to ask.

Your designs always look really cool! How long does it usually take to get a nice shine on SS? I want to make about 10 of these for my group of friends, and tumbling seems like it would take an extremely long time in my dinky machine if it works at all (an expensive experiment!).

I wouldn't need anything to get between the details, since I'll be filling them in with coloring, just shining for the face of the ring and its body. Do you have any suggestions for a basic setup that would do that? My budget is kind of tight...

Thanks in advanced for your help!

Cheers.
For a real polished, smooth finish I've got the time down to about an hour or so using a Dremel type rotary tool with an 80 grit sanding drum, followed by 400, 800 & 1200 wet & dry sandpaper on a drum (auto spares type stores carry these), then I buff the item up using some Brasso (liquid metal polish) and a felt wheel. If you're on a tight budget, have the time and don't mind ruining your nails, you can do all of the above by hand.

For a buffed up finish, I use a wire wheel in the dremel or a wire brush followed by Brasso. Again, without power tools this can be done by hand, but takes longer.

SS doesn't rust, Shapeways SS is infused with bronze so the pinkish color you see is likely copper.

Many jewelers use tumblers for polishing, they use steel shot with soapy water, it burnishes the surface. If you want to actually refine the surface, you can use any one of a number of abrasives. Either a powder grit with plastic pellets or cer5amic pellets with embedded grits.

It's defiantly rust, since it's a steel/bronze amalgamation. Steel and Bronze aren't rust proof without some sort of coating or treatment. The oxidation showed up in the signet after multiple hand washes over a 2-3 days.
