I started making the following pressure gauges for model steam engines. One of the more challenging parts to this is getting a good polish on the face. The gauge itself is a commercially available pressure gauge which I rip the face off of and place a custom etched face on top of.
Polishing these tiny little things with a traditional buffing wheel and buffing compound can be a real pain to get it perfect. The hardest task is holding them while polishing and they tend to get really hot as you go about it and they never come out just perfect. Perhaps a better wheel special for brass?
Anyone have any good ideas here? What is the best metal finish process to have done to these? I know there is electropolishing, bright dip and other processes that may work here. Any one have any ideas?
I reached out to my etcher and asked if we could start with polished sheet and the reply back was that the photo resist doesn't really stick well to the ultra smooth surface so it seems like a secondary process is still required.
