SUBSCRIBED. I wanna see how this unfolds.
I'll throw another wrench into the works. Get some tiny piezo discs, like the ones you can find in some greeting cards. Digikey and Radio Shack sell them, too. A person could probably attach them at various places on the steel and pick up different tones depending on placement. Use a dab of silicone where the wire attaches and maybe solder on so small shielded wire. The impedance on the piezoceramic shouldn't be so far off from what guitar amps expect and could be resistively summed if you used more than one transducer. If the input impedance were an issue a very simple JFET or MOSFET preamp (probably a source follower) would take care of it and drive a cable and DI or guitar amp without capacitive loss that piezo is prone to.
OR...carefully remove the handle from the saw and slightly widen the slot to accept an acoustic guitar saddle transducer. The transducer would pick up any vibration at the wood/steel interface.
I suppose there are a lot of ways to do this. Good fun!
