I recently bought a tool called a Rockwell Blade Runner. It is like a scroll saw turned upside down in a small table, with a blade guide/guard above it. I haven't tried to cut piano wire with it, I just use a hacksaw with a fine blade for that, but it is great for cutting brass strips, even up to 0.0625 thick. I recently also got some 3/4" square brass tubing to make motor brackets, and this tool could cut through the face of the tubing that is also 0.0625 thick. The piece of 1" square may be pushing it a little, but I will try that next. It is also a small enough size for my limited workbench space.
The tool came with blades for wood, metal and ceramic, and cuts cleanly with no wandering. It is quite loud, so if you get one, be sure to wear ear protection and safety glasses. The good thing, no more need to solder 1/2" brass strip pieces together to make a rear bracket that may end up being a bit wonky.
Cheers,
