I’m building the four steam rifles today.
They are supposed to be repeating ball-shot steam rifles with pressurized
backpacks. I was more than a little inspired by The Last Exile but the end result may be more reminiscent of Ghostbusters. Still, here is the basic plan I am working from. We lucked out by finding some recessed lighting fixtures that will make building the entire thing much easier. Still, as I have four identical units to produce, this will be quite a job.
