That looks fantastic! What did you use for the brass overlays? I've been wanting to do an MHS-based build with brass bits but I'm not sure where I can get brass tubes that will sleeve over the MHS parts without too much fuss (other than stripping the chrome off a sink tube, of course).
I ended up finding some raw-brass sink-tubes at Lowes, no chrome! Although, I ended up sanding the outside down to get it pristine, too. I didn't have to worry about stripping the chrome, but that would probably happen through my sanding process anyway.
