i have a big ugly instrument idea that is unfolding into reality. it's
a 2' by 5' piece of stainless. bass hardware holds fat piano strings on
one side and on the other i want to weld stays to support a large
spring which i can hit with a metal rod. i will tune the strings to
resonate a certain chord when the spring is struck. i have some old
dimarzio bass pickups for under the strings but im wondering if a
contact mic would work on the sheet metal, or other ideas?

I have a suggestion for you that's completely off the wall:
Use autoharp-style keys and strings tuned chromatically. That
way, when you hit that spring, you can actually change the
chord that resonates afterwards.

If this is relatively thin stainless sheet metal, how are you going to
tension the strings without bending the plate?
