The wire has resistance, hopefully calculated correctly here, and that should limit the current that it can draw from the PSU.

Your situation is a bit more worrisome (with a fixed supply) than with a variable supply because with a variable you could slowly ramp up and would notice any problem. With a fixed supply, it's a one shot deal, and you're the first to try it as far as I know

Let me double check one thing I've just noticed here -- the current shown is the same for the 16" x 1.5 V bow as it is for the large bow. I just want to make sure that is not a mistake. We haven't tried a fixed supply or anything with wire as thick as yours -- so working with a small range of what is possible.
