Metal Mechanical Power Parts

[VaelophisNyx]

Conceptually it'd make some sense to smith mechanical power axles and gears, though no better than their wood variants. Smithing large gear parts would also be likely expensive or otherwise difficult, but interesting

Main gain in my mind is they'd probably not contain any resin, rather using more fat as a lubricant

though it'd be neat if they were able to be made of any hard metal from bronze and beyond, and potentially with a requirement to make inter-meshing gears of differing metals to prevent cold-welding
