Yes, one of my main reasons for buying some was to make bends in very small copper tubing I was using for steam piping on a model engine. It worked very well for that purpose.

I hadn't thought of the plating method for making thin shells but I'll certainly keep that in mind for future projects; sounds very ingenious.
