Nice! :)
Have you thought about motor-driving them and lapping them with abrasive to
automate the smoothing?
They also use a grease with particulate copper in it for Glocks and other such
items - perhaps a quick electroplating or just dumping the iron parts into a
copper sulfate solution (bluestone) to do a non-galvanic plating via a surface
redox reaction would give you slightly copper-plated gears which might run more
smoothly... or not. ;)
