Very cool. What material are you using for etching the bicycle and
motorcycle. What are the smallest dimensions you are able to etch.
I have given some thought to trying to etch small brass parts like
gears, but have not gotten around to trying.
Also curious about the laser cutter you used. What brand are you
using. Have you tried using it to ablate a resist layer off a metal
layer. Maybe something like black paint on metal.
