Cool! Have you seen the stuff at Twenty Gauge or Sonrisa? Gorgeous stuff. I have a tanker desk sitting in my garage waiting to be refinished -- a double pedestal, with really unique handles. I, too would like to get it down to bare metal. I tried painter stripper, but it didn't work too well on the original enamel finish. You could try an orbital sander, the swirl marks could be an interesting texture. But from what I've found in my research, the best method is sand blasting, then several stages of sanding, followed by a powder coating to protect the metal from rust and corrosion. Good luck with your desk, please post pictures!
