Thanks guys! It's secured to the stand, Christian. The pole was cut at an angle, and then some velcro holds the bio on there, and there's another piece of wood that comes out from the pole at 90º, and the bio rests on that, just above the visor, to keep it at that angle.
As for the how...well, it's not the scouring pad method in my vids. It's actually quite a bit more involved, and involves a couple of coats of metal coatings (water based paint filled with metal particles), then patina acids, then metal rubs, coloured waxes, and if I feel like it, some airbrushed detail. The airbrushing on this one is minimal.
