TwystNeko wrote to say they were greatly inspired by Mr Von Slatt’s brass engraving tutorials, and has been dabbling with it ever since.  Indeed, they’ve created two cog-featured .psd templates (such as the one above, though without the text) that others may download and use for their own etching!  In particular, it has been designed to use as name plates or book labels – I imagine they’d look particularly fetching on the side of a wooden case filled with all manner of items.

TwystNeko has also done some other good etching stuff, with an etch of the Steampunk version of Optimus Prime (from the Hearts of Steel comic) and a rather insanely detailed cover plate from the film version of Star Gate.  If etching is not your thing, then the .psd’s are fully layered and available to play with – those cogs are lovely and even fit together properly.  Thank you, TwystNeko!
